68. Season of mists and mellow fruitfulness – riding in fog

Fog remains one of the trickiest hazards for motorcyclists, particularly at night or in low-light conditions. Research supports my discussion of visual disorientation and increased reaction time. Modern lighting may help see, high-visibility gear might help others see us — hardly any bikes have a fog light, but the core principles haven’t changed: reduce speed, generous following distances, and riding to what we can actually see, not what we expect. Ultimately, preparation and anticipation remain the rider’s best defences—fog is never enjoyable, but with forethought, it can be managed reasonably safely.

Season of mists and mellow fruitfulness – riding in fog

I’m pretty sure Keats didn’t ride a motorcycle, but it’s not unusual for spells of settled weather to develop during late on in the autumn, and fog can be a major problem. I still remember two trips vividly. Years ago, when I was only a few months into my riding career, I rode from Maidstone in Kent to West Drayton near Heathrow. The ride took twice as long as expected because the fog came down, and I very nearly didn’t make it. Following the kerb along the inside lane of the A40, I didn’t notice I had drifted off the main carriageway into a slip road. I nearly collided with the Armco barrier on the corner. Thankfully because of the thick fog, I was only riding at about 20mph and took some evasive action. A few years later when I was despatching, I took a package from London to GCHQ at Cheltenham. I left in lovely afternoon shine. I got to Cheltenham in time for a beautiful sunset. And the return ride turned into a nightmare of freezing fog, accidents and traffic jams. So riding in fog and particularly in fog at night, is probably my least favourite part of biking. And if I can, I’ll stay put. But sometimes it has to be done. So what are the problems and how best to deal with them?

Fog forms when moist air travels over colder ground. Although we could encounter for at any time of year, the densest fog often forms in autumn – November is a favourite month for fog. Warm air can still make its way up from the near-continent and it holds more moisture than during the winter months. But the nights are long and fog forms more readily than in summer, and it can be slow to clear – it may even persist all day.

Like all other weather-driven hazards, first stop is the weather forecast. Forewarned is forearmed. Find out what the day-long forecast is. Whilst fog may be slow to clear in the morning, it’s pretty obvious when we wake up in it. But if the weather changes and become clear and still during the day, fog can easily be a problem on the dark ride home. Maybe we can change our departure times.

Towns are generally a bit warmer than the surrounding countryside so it’s not uncommon to drive out of town into fog. We can anticipate where we’re likely to find it. It can be low cloud, so worse on tops of hills. Or it can be caused by cold air that’s sunk into low-lying areas after a still, clear day – damp meadows and river valleys are classic places for fog to form on still evenings. Or it can be blown in off the cold sea. Kent, where I lived for many years, used to get all three types. For example, the M2 being near the coast would often be affected with sea-fog. But the M20, being a few miles inland and crossing the North Downs, was often affected by hill-fog. Watch out for patchy fog, because we never quite know where it is, how thick it is, or how long it’ll last. Don’t be tempted to blast into a wispy looking bit of mist drifting across the road. It could be a lot thicker than you think.

It’s often cold riding in fog, thanks to chill air temperatures, but also because the tiny droplets evaporate from clothing and suck away body heat. If riding in leathers, put waterproofs on, and layer up to stay warm.

On the bike, the first problem is simply seeing out the helmet. The visor gets covered with water droplets on the outside and mists up on the inside from your breath.

Wax polish like Mr Sheen on the outside helps the water bead up and run off, often just by turn our head. Try to avoid wiping a finger – the oily crud on the glove gets smeared across the visor and makes it even more difficult, and long term it scratches it. If the visor gets covered in salt spray or road film, a damp cloth kept in a ziplock bag (I spray that with Mr Sheen too) can clean and re-wax the visor.

Holding our breath all the way home is impractical, and I’ve never yet found a helmet that demisted itself from the vents that were supposed to perform that trick. Breath deflectors also help, but an anti-mist treatment is usually needed. Whilst they do seem to work, they need regular reapplication. Quite honestly, I used Fairy Liquid as a courier, applying a dab of the neat stuff, then polishing it on with a clean cloth. The other option is a Fog City-style add-on. It’s effectively double-glazing for the visor, but I’ve found that at night they reduce visibility, partly because they scratch easily. I’ve heard they can be tricky to seal effectively on some visors.

Having sorted yourself out, make sure the bike is in good shape too, with clean and properly adjusted lights. If dip beam is too low we won’t get any forward vision. If it’s too high, even on low beam it will light up the fog – now the light’s bounced back as glare. Extra-bright lights can actually be a disadvantage when this happens.

One of the problems of riding in fog is a sense of ‘dislocation’. A road we’ve ridden dozens will seem totally different in fog, as our normal visual cues will vanish. So use everything available. Reflective posts are red to the left and white to the right, so if we see a line of red posts, we’re approach a right-hander. And vice versa. Triangular warning signs are reflective and are there to flag up hazards. Watch the centre line – longer ‘hazard lines’ indicate just that, and cat-eyes get closer together too when approaching a hazard, and really close – almost a solid line – when the centre line goes solid. Coloured cat-eyes help on multi-lane roads – red to the left, amber to the right, white between lanes, green where vehicles leave or join a carriageway. Ride to what you can see, not what you think you ought to see.

In general I try to follow the centre line rather than the left hand edge of the road – it keeps you further from dangers to the left which will be harder to see – but be cautious entering cross-hatched zones in the middle – there may be unlit traffic islands in the centre of the road.

Unless we meet someone with no lights, it’s usually easy to see oncoming cars, but side-on there’s little to warn us. We can normally see the tail lights of cars ahead, but don’t simply follow the guy in front – if they run off the road, so will we. Fog’s water so it makes the road surface damp, and potentially very slippery, so a good following distance is important.

We need to remember that with no fog light, the driver behind us will have difficulty seeing us against the brighter lights ahead in a queue of traffic. If we do a lot of foggy miles it might be worth fitting one – I used to fit a fog light as a courier. I’ve also seen riders using bicycle LEDs and was surprised how effective they were, although technically they are illegal if fixed to the bike. Typically, reflective material on hi-vis vests is too high up when everyone is driving on dip beam or fog lights – it needs to be low down to be seen.

And finally, make sure the bike’s easy to ride. Many riders use ‘rat bikes’ for winter riding, but make sure everything works properly – we need every ounce of attention for riding, not to worry about stiff clutches, dodgy brakes or cheap and nasty tyres.

Riding in fog is never fun, but we can make it less stressful.

66. Riding in hot weather – avoiding dehydration

The article is highly relevant, particularly since summers in the UK are getting hotter and hotter. Riding in extreme high temperatures continues to pose a real risk of dehydration, heat exhaustion, and impaired concentration for motorcyclists. The physiological explanations (sweating, fluid and electrolyte loss, impact on kidney function, early fatigue, and later confusion) are all accurate and still supported by modern sports medicine and physiology research. One correction is that modern research suggests moderate caffeine intake is not strongly diuretic in habitual consumers but energy drinks can be counterproductive due to high sugar content. Heat stress is compounded by full protective gear but modern ventilated jackets can aid air flow and cooling if humidity is not too high. It’s also possible to get sunburn through a visor; packing and using sunscreen is a good idea. Don’t ignore the signs of heat stress. Dizziness, headache, nausea, rapid pulse, or cramps can indicate heat exhaustion before severe dehydration sets in.

Riding in hot weather – avoiding dehydration

It always seems to happen. One week I’m riding around wishing I’d remembered to wear the heated waistcoat, then we get a few days of ‘scorchio’ weather. Riding a motorcycle in protective kit on a hot day sets up a unique combination of overheating and sweating, and a cooling and evaporating breeze. The body’s physiological functions only work in a narrow range and if we get too hot or cold, we get disorientated or worse. So the body tries to maintain temperature of around 37 degrees by sweating. The result is a high risk of dehydration at the same time as we’re struggling to stay cool. So what are the dangers of running short of body fluid?

Body fluid and electrolytes are vital to the function of the body’s organs. If they are lost through sweating and if they are not replaced, we suffer dehydration. In the early stages, we get rapidly fatigued and start to lose concentration. In the later stages more serious confusion sets in, and the body’s metabolic functions start to be affected. Not good. And that’s why I send out a notice to riders to ensure that when they attend a Survival Skills advanced rider training course, that they pack some water.

So what are the symptoms of dehydration? A good sign that we are dehydrated is not “feeling thirsty”, it’s not needing to pee! That tells us kidney function is already shutting down to save fluids. By the time we do feel thirsty, with dry lips and a dry mouth, then we are already well into the early stages of dehydration.

Most UK riders are oblivious to just how real a problem this, even when riding at home in a British summer. In countries like Australia, New Zealand, South Africa and the US where they ride long distances in hot and dry conditions, they are much more aware of the risks. You’ll also see racers taking on board fluids just before the start. But dehydration doesn’t only happen to racers. Whilst we’re not working physically so hard, we’re often exposed to that cooling breeze for longer.

So what can we do to prevent dehydration?

Planning ahead is the answer. We can start by pre-loading with fluid before we go out. For sports like cycling and soccer, it’s recommended that we drink around half a litre (roughly a pint) of fluid a couple of hours before we begin. Then around 15 minutes before setting off, aim to drink another half litre.

On the move, we need to keep replenishing fluids. It’s easy enough to take a bottle of water with us, so we can take a drink when we stop. For sporting activities, it’s recommended that we take around 100-150ml every 15 minutes or so when exercising – that would be around a half-litre bottle of water every hour. Given a particularly hot day, that’s probably not far off what we should be drinking on a bike. I took a Hopp Rider Training day at Cadwell Park on a warm autumn day, and we were reminded to get some water on board before going on track, and regularly reminded to rehydrate between track sessions. Doing it right, we should be making regular loo stops too. If that’s inconvenient, so be it. It’s better than the side effects from dehydration.

Riding alone, we can stop when we like, but on a bike with a 250 mile tank range, don’t wait till refuelling stops. Definitely make intermediate stops – remember, if you feel thirsty, you are already dehydrated. Group rides tend to go on too long, and we’re all dependent on the leader deciding when to pull up. So if you’re organising a group ride and you know it’s going to be a hot day, then factor in short breaks at regular intervals, and try to get people to use the opportunity to top up – you don’t want dehydrated and underperforming riders with you.

There’s a lot of marketing surrounding isotonic fluids – these are basically water plus the electrolytes we lose in sweat, so they have the advantage of keeping the chemical balance of the body right. You’ll find them in most service stations. Isotonic drinks also come in powder form – you can buy tubs of the stuff from any cycle shop and make up a couple of litres for the ride.

Personally I’m not fond of fizzy canned drinks because they are generally sweet and sticky. Coffee is generally considered a diuretic (ie it makes you pee more) but lately there’s been some debate about whether the old advice to avoid caffeine-based drinks is actually correct, although it’s generally accepted that the so-called energy drinks aren’t good for rehydrating. Personally I prefer tea – it’s not nearly so strong a diuretic and I like it!

However, they all cost a lot more than plain tap water!

So what to carry fluids in? I avoid buying plastic bottled water, partly because the plastic is liable to split when wedged into a pannier or under an elastic strap, and partly for environmental reasons. Any cycle shop will sell you a plastic water bottle – they are (just about) unbreakable and will squash – or an aluminium bottle. A little more cash will get you an insulated plastic cycle bottle or a Camelbak which is a plastic bladder that sits in a backpack harness – fill either with ice cubes in it, top up with water and even on a hot day, you’ll have something cool to drink for a hour or so.

A couple of final warnings. Steer well clear of alcohol. It might be tempting to sink a nice cold pint “because I’ll be well under the limit” but if you’re rehydrating, the alcohol will be absorbed faster and be even more disorientating than normal.

And… DON’T drink ice-cold water. The thermal shock of pouring ice-cold fluids into the stomach fools the body into thinking it needs to shut down the sweating mechanism. That’s definitely not what we want.

46. Six Tips for riding in strong winds

Modern riders benefit from weather apps with real-time wind forecasts, even GPS alerts, and which make planning safer and more precise. But the physics involved in the interaction of motorcycle and windy weather hasn’t. And there’s nothing that modern electronic aids can do either, when the bike’s hit by a sudden gust from the side. Rider knowledge and skill is still the only way to go.

Six Tips for riding in strong winds

Most years, Britain is battered by winter storms, and even in the autumn we’re increasingly being affected by the decayed remains of Atlantic hurricanes that still produce strong gales. Even in mid-summer, a thunderstorms can generate surprisingly strong, if localised winds. And of course it’s always windier on the coast or high in the hills. So what are my Survival Skills tips and the best way to deal with strong winds? As always, the first stage is to plan ahead. Before anything else, watch the forecast. That might seem obvious but what looks like nice morning weather out of the window can change in a couple of hours to a gale-wracked afternoon and it might be a good idea to travel another day. Maybe we can take the car or the train. But what if we have to ride? Here are some handy Survival Skills tips for riding in strong winds.

REMOVE LUGGAGE IF POSSIBLE – don’t forget that luggage on the rear of the machine acts as a ruddy great sail – top boxes can really destabilise a bike in strong winds. A magnetic tank bag can be blow clean off the tank too – don’t ask me how I know (I always tether a tank bag to the keyring fob with a carabiner now). If it’s possibly to take any bags and boxes off, do so. Baggy clothing and rucksacks aren’t a great idea either. If there are cinch straps on sleeves or legs, tighten them up. And if we’re going to carry a passenger, get them to sit as close up as possible so there’s no big gap between rider and pillion.

PLAN THE ROUTE – defore setting off, do some route planning. Try to find roads that are not so exposed. A roads are generally more sheltered than motorways. Roads in the lee of hills will be less windy than roads along the top. It may be possible to plan the route so that on exposed roads the strongest winds are behind us, rather than from the side. And we may need to change route mid-ride. Many years ago on a despatching job to Northampton, a windy Chrismas eve morning turned into a full gale by mid-afternoon. The M1 was a real struggle – I recall a furniture lorry being blown up onto two wheels as I passed it. Rather than attempt the M25, I came back through central London. It turned out the newly-opened Dartford bridge was closed anyway. By the time I was back out on the M20 and heading home in Kent, the wind had dropped.

SPOT THE PROBLEM AREAS – once on the move, do a bit of amateur weather forecasting. The strongest winds often blow around squall lines and thunderstorms, so spotting a tall, dark cloud with a tell tale-rain shadow beneath it should ring alarm bells. Look ahead and figure out where the wind will catch us:

exposed roads, particularly motorways

high bridges

open roads

coastal areas

roads across mountains and along mountain valleys

gaps between buildings and hedges

as trucks pass

below high rises in cities

etc etc – I’ll leave it to you to think of other examples.

WORK OUT WHICH WAY THE BIKE WILL BE BLOWN – usually it’s in the direction the wind is blowing, but there are three exceptions:

passing trucks – if the wind’s coming from the far side, we’re suddenly sheltered and we’re actually sucked in towards the truck, then as we get level with the cab, we’ll be suddenly blown away again

halfway down hills – there’s usually a back eddy where the wind suddenly reverses direction. The M20 halfway down Wrotham Hill is notorious for this

alongside high rise building – the building deflects the wind so it blows in the opposite direction at groundlevel is in the opposite direction, so we can be hit by winds which change direction through 180 degrees in a few metres in city centres

Other problems? Look out for fallen branches and general vegetable detritus blown from trees. Wheelie bins get blown into the road. Fences may come down. I’ve even seen a shed collapse into the road.

STRATEGIES TO SURVIVE – so if we know when and where we’re likely to be blown of course, we can at least prepare:

ride on the side of the lane which gives us the most room to be blown sideways

keep well away from high-sided vehicles, and give a good clearance to those coming the other way – they’ll be pushing the wind in front of them

don’t try to hang onto the bars – instead, keep the shoulders, elbows and wrists as loose as possible but locking the knees against the tank and brace our back. That way when we’re blown around on top of the bike, we won’t take the handlebars with us, and it’s much easier to steer a reasonably straight course

be ready to steer into the wind

remember counter-steering – if the bike is being blown TO the left, we need to steer INTO the wind by pushing on the RIGHT handlebar end.

Strong, sidewinds are knackering. I had to ride 200 miles due south across the Mohave Desert with a 50 mph wind coming from the west. Absolutely NO cover from the wind. My arms, shoulders, and back burned by the end of that ride. The only way I made it was by hanging my backside off the side of the bike facing the wind. Try it, and you’ll find it helps the bike to steer into the wind. And that means a little less effort in holding a constant degree of steering into the wind.

I can’t emphasise how important it is not to ride with stiff arms. If we’re hanging on for dear life, every time our upper body gets buffeted, we feed that straight into the steering and we make all the wobbles and weaves much worse. Keep elbows loose but the wider we hold the bars, the more leverage we have to steer into the wind and the less ‘push’ we have to make which means it’s less tiring.

DO WE SLOW DOWN – there’s often a suggestion that if we slow down, we feel less ‘blown about’. Well, that may be true into a headwind but if the wind comes from the side, we might feel less buffeting on our chest. But the sideways component of the wind remains exactly the same, plus we lose the benefit of how straightline stability increases with speed. There’s a trade-off where too fast becomes a problem because we get blown off the road quicker than we can deal with it but it’s certainly possible to ride too slowly in wind – the clue is we’re wobbling all over the place.

Some bikes are better at handling wind than others. Part of the problem is the design of the front wheel. Harleys with solid disc wheels have a bit of a reputation for being unstable in crosswinds, and so did the 80’s Hondas with the ‘Banana Comstars’ – I had an XBR500 and this was an absolute pig in high winds – I could feel the wind blowing the front wheel around and trying to yank the bars out of my hands.

I can’t claim riding in strong winds is fun. If we have to ride – as I had to on that journey back from Northampton – we can’t stop the bike being blown sideways, but like most things, there are strategies for dealing with the problem. It’s hard work, but with a bit of thought and forward planning it need not be quite so scary.

45. Eleven Essential Tips for riding in the rain

The advice is still very relevant, especially the emphasis on spotting slippery surfaces, progressive braking, careful cornering, and anticipating changes in grip. Modern bikes, tyres, and safety aids have slightly shifted the context, but the fundamentals of wet-weather remain the same, with the emphasis on spotting slippery surfaces (manhole covers, white lines, tar seams, leaves) and anticipating how those surface changes will affect traction, remaining critical.

Eleven Essential Tips for riding in the rain

Rain means wet roads, and wet surfaces means less grip than in the dry, and so we’ll have to reduce our throttle openings, lean angles and increase our braking distances accordingly. The question is “how much?”. Unless we have some idea of how much grip there is, we don’t really know how hard we can accelerate or brake, or how much lean we can use. And we can end up being excessively cautious and then we’ll be harrassed by other drivers. There is nothing wrong with taking care in the wet, but too much caution and we start causing ourselves even more problems. So let’s have a think about the issues.

HOW LONG HAS IT BEEN RAINING – this should be our first question. Prolonged rain flushes surface contaminants away and given a decent surface, wet roads usually have plenty of grip. . But if it’s only just started raining, particularly after a prolonged dry spell, expect the surface to be super-slippery. Oil dripped onto the road mixes with the worn rubber on the surface, creating a slick.

KNOW WHERE TO FIND GRIP – a wet surface that is in good repair and clean, modern tyres should have good grip – it’s a bit hard to put a figure on it, but at least 70% of dry grip should be available. And high grip ‘Shellgrip’ style surfaces give near race track levels of grip even in the rain.

AND KNOW WHAT’S SLIPPERY – but what about the road that’s not in good condition or is contaminated? Some surfaces which are fine in the dry are appallingly slippery in the wet. Now the problem is that no matter how good our tyres, they won’t grip if the road surface cannot deliver its half of the deal. And the quality of the surface has been steadily deteriorating for the last three decades and right now finding a perfect surface is now the exception rather than the rule. So be on the alert for surfaces which are slippery when wet:

metal manhole covers
cats-eyes
white lines and road markings
bitumen tar seams where tarmac is sealed
polished and worn road surfaces
oily surfaces
leaves

Here’s a clue. Most things that are shiny when wet – even leaves – are slippery! So treat any shiny patch on the road as potentially slippery and something to be avoided if possible.

KNOW WHERE IT’S SLIPPERY – and then avoid or take care in those places. A big fear for bikers is spilled diesel. Although figures published by FEMA (the European rider rights organisation) claimed that 10% of all motorcycle accidents were caused by diesel, UK figures suggest it’s less than 3%. Whatever the truth, there’s no need for us to become one of the statistics by being cautious where spills of fuel and oil are most common:

roundabouts
near industrial estates
by garages
on bends and at junctions
between the wheel tracks at traffic lights or stop signs

Treat dark shiny streaks or rainbow patterns with care, and use your nose – you will often smell diesel before you spot it. And remember petrol is JUST as slippery as diesel.

SPOT SURFACE CHANGES – as I mentioned, we may ride from a grippy surface onto a less-grippy one, so we need to spot that as early as possible. Look up the road and try to spot a change of colour. It’s almost always a change of surface. We won’t know whether it gets better or worse, but at least we’re on the alert. A visible line often warns of a change. Oblong shapes are usually road repairs. Irregular areas of a different colour could be a damp patch, a pothole or loose gravel. Streaks are often a fuel spill.

BE ALERT FOR SURFACE WATER – there aren’t too many around but on minor roads, we could come across a ford. Take it cautiously and upright and don’t brake or accelerate hard – they are often slippery with algae under the water.

After a thunderstorm, watch out for surface water beyond the norm! After prolonged or heavy rain, expect flooded surfaces. Avoid riding through puddles as a matter of course – they may conceal a pothole or debris. There’s a minor risk of aquaplaning on standing surface water but watch out deeper water which can cause a loss of control if hit at speed. Any depression is likely to be filled with deep water. Underpasses often flood to surprising depths. Look to see where the kerb disappears to get an indication of how deep it might be.

Watch out for mud, gravel or debris carried into the road. I’ve had to dodge a sizeable log before now. Streams may burst their banks and flow into the road, and we not only have to be careful about the depth of water – look at fence posts or the hedge – but there could well be a strong current. It might be wiser to find an alternative route than attempt to ford it.

KNOW WHEN TO SLOW – in wet weather, many riders will slow down unnecessarily, even when it’s safe to maintain a decent rate of progress. It’s stopping distance we mostly need to worry about, and whilst it increases with speed, if we stretch our planning and open up our following distances, then it should be OK to maintain speed to go with the flow to avoid being tailgated by impatient drivers.

AND WHEN IT’S MORE IMPORTANT TO KEEP A GAP – one of the biggest wet-weather faults I see is following the vehicle ahead too close, too fast. Braking distances increase in the wet, but it’s not just stopping distances we need to worry about. We need to understand how changes of surface affect our ability to stop and maintain control. We really don’t want to find we’re braking over a wet metal access cover that just popped out from under the car ahead.

AIM TO BE SMOOTH – what breaks traction in the wet is often a sudden application of brakes or throttle. Whilst modern bikes have ABS and traction control is becoming common too, kicking either in is not a good idea as it’s disconcerting. And without these aids, there’s a risk of a loss-of-control. Aim to be smooth, but also to be minimalist – the fewer control inputs that achieve a particular result, the better.

Aim for progressive braking. Once the suspension has compressed we can build the pressure – most riders are surprised how much grip is available if we don’t grab a big handful of brake.

Don’t make the common mistake of trying to stay off the brakes then finding you need them at the last moment. Brake early and positively rather than late and harshly – it not only improves stability but gives us options. If we brake earlier than necessary, it means we can release the brakes again if we are unable to avoid crossing a wet metal cover or a painted arrow. That takes away the fear of locking a wheel as we ride over it, and we can reapply the brakes on the other side. It’s not very difficult IF we look ahead and think about what we are doing.

Know how to corner in the wet – there’s no real difference in technique, but it’s more important we get it right. Don’t try to turn in on a closed throttle or on the brakes – if we do, we’re loading the front tyre with deceleration forces just as you want all the grip for steering and it’s easy to lose the front if we hit a slippery patch. Instead, get the braking done upright, get off the brakes in a straight line to let the suspension settle THEN turn in smoothly.

Just as in the dry, the best way to enter a corner on a wet road is back on the throttle, keeping steady power on through the turn, which means using the Point and Squirt late apex approach I teach on Survival Skills Performance Courses through the corner. The biggest steering errors are to turn in too early which guarantees we’ll run wide on the exit, then probably touch the brakes mid-corner to try to lose speed – in the wet this is even more a recipe for disaster than in the dry. In fact, mid-corner, we can probably lean over further than we might expect, which is the way to deal with a tightening bend, but try to avoid sudden or jerky motions. We don’t need to corner at walking pace but just a modest reduction in speed means we can make our direction changes a little more gentle, and use a little less lean angle mid-turn. open out your lines a little and make them smoother. Err on the side of ‘slow and smooth in, and faster out’ – it’s not that important to ride fast in the wet.

Don’t try to open out the exit to the turn by taking a wide, sweeping line. We may need to change line to keep off tar seams, access covers or white paint mid-corner. If we’re on a line that gives us no way of changing position should we need to, then we’re potentially in trouble. If we’re on a sweeping line and aiming for the extreme edge of the lane, and we do experience a slide, we’ve no room to recover. In the wet, I avoid extreme cornering lines – so I can compromise my perfect line to avoid slippery areas. I usually ride in the middle third of the lane, so I have some room for error.

If we must brake in a corner – perhaps because the road ahead is blocked – then use BOTH brakes lightly. Remember – if you’ve not already crashed, there is SOME grip at the front. As the speed comes down, our lean angle usually comes up, and so we can brake progressively harder. The important thing is not to grab at the front brake. With no ABS we’ll probably crash (I’ve bought that tee-shirt), with ABS we’ll have a moment to recover. Although it may be easier to catch a rear wheel lock-up, the rear brake alone won’t offer much braking.

Don’t try to accelerate mid-corner when the bike is still leaned over. A surprising number of crashes in autumn, when the roads are first wet and cold, happen when riders accelerate whilst still leaned over, often when turning right at a junction or a roundabout. The combination of lean and throttle breaks grip and the rear. The answer is to get the bike turned completely THEN open the throttle. Even with traction control, it’ll still make for a smoother turn.

UNDERSTAND HOW TO USE THE GEARS – don’t make the mistake of believing the old advice to ride in a high gear on a slippery surface either. Whilst that might have been effective on a low and slow-revving 50s and 60s Triumph, modern sports bikes will spin up the rear wheel the moment it breaks traction. Wheelspin in a straight line is controllable, just a gentle wag from the rear of the bike. If we’ve not got traction control and we wheelspin in the wet whilst leaned over, we may not get the throttle shut again in time to prevent a crash. Let the engine rev, but accelerate gently – don’t open the throttle so far as in the dry.

And one final piece of advice – KNOW YOUR TYRES – if you intend to ride all year round, fit sport-touring tyres for the colder months of the year. The soft compound sporty tyres really only work in warm weather, and will never get hot enough to grip effectively in cold rain. Sport-touring tyres may not have the ultimate level of grip but they’ll work better on wet roads at any time of the year, and they generally slide more predictably than the grippier tyres that just let go suddenly.

Having just listed all the problems of riding in the wet, you may be surprised to know, I actually enjoy riding in the rain. It can be a lot of fun!

38. Staying upright on icy roads

This article remains fundamentally sound. The core message — avoid ice if at all possible; if you cannot, prioritise stability, smoothness, and planning — is still exactly right, and the last update which mentioned less-predictable winter weather continues to be a factor.

That said, a few areas benefit from clarification or modest updating, mainly around modern tyres, electronics, and rider aids, and one or two points where rider folklore still needs firmly nailing down. Many modern motorcycles are fitted with ABS, traction control and sophisticated engine management, and while these systems can reduce the consequences of rider error, they do not change the basic physics of ice. ABS may prevent an immediate front-wheel lock, but it cannot shorten stopping distances on ice and may actually destabilise the bike if it intervenes abruptly. Traction control reacts only once slip has already occurred, and on ice a sideways slip may be unrecoverable. Likewise, modern tyres offer excellent wet-road performance but still provide virtually no usable grip on ice, regardless of compound or tread pattern. Riders should regard electronic aids as a last line of defence, not a licence to continue riding in conditions where grip is fundamentally unavailable.

Staying upright on icy roads

This is another article which has needed a bit of a rewrite, because global warming seems to have spun off some seriously cold winters with snow and ice hanging around for months even in the south east of England. However, just as I wrote when I first put this tip together, the best solution to dealing with ice is to try to avoid it in the first place! I have a ‘bad weather’ clause in my training courses so it’s usually possible two or three days out to get early warning of approaching bad weather – the weather forecasts have improved significantly in the last decade or so. Failing that, take a look out of the window and have a look at car windscreens and the lawn. If it looks grim, take the car, the bus or leave the ride for another day. I was a ‘real biker’ for many years and learned the hard way that two-wheelers and ice don’t mix.

The best advice for riding on icy roads is “don’t”. But if there’s no choice, then do a bit of thinking ahead. Although it can stay frozen all day, it’s usually freezing mornings after a clear night that are likely to be the biggest issue, although the roads can freeze again if cloud clears after dark.

Plan the route to take roads that are more likely to have been treated. Back lanes are far less likely to have seen a gritting truck than main roads, and residential roads roads are more likely to be icy than motorways. Where cars have been running over the road, heat from the tyres will usually melt the ice in the wheel tracks, but if all the surface is icy, the least-polished and grippiest bit of the road is generally in the middle of the lane. A good indicator of a slippery bit of road is that it is shiny.

Remember too, that built-up areas are nearly always significantly warmer than country roads and just because the roads in town have been clear, that’s no guarantee there will be no ice on rural roads. Even if the road appears clear, there may be colder frost hollows or exposed areas where it isn’t – this is the ‘microclimate’ effect talked about in the police handbook, ‘Motorcycle Roadcraft’.

We should also look for ice in shaded patches, behind buildings and under trees, even behind parked high-hided vehicles. If water can pool, such as in dips in the road and at bottoms of hills, we should keep our eyes open. Watch out for run-off from springs and fields – a good clue is an anti-skid surface! Car washes in towns can overspill and burst water mains nearly always accompany really cold weather. Be cautious on bridges – they cool from both sides – and metal access covers can be icy when the road surface is still just damp.

One particularly unpleasant riding condition is ‘black ice’. It’s hard to spot because it looks like a wet road but is actually a sheet of ice. The only clue is that it looks ‘wetter’ than usual, if that makes sense. It usually follows a late evening shower and clearing skies and a frost. Years ago, returning from a blood run at 4am on a January morning, I was passing through the town centre thinking it would be warmer than the country lane route home, when I hit a patch. Fortunately I was upright at the time, because what I thought was a missed gear turned out to be wheelspin. If I’d been accelerating coming out of the corner, I’d have been on my ear. As it was, I was able to roll off the ice and back onto some grippy tarmac.

So if we suspect ice, aim to get any braking and gear changing done upright, and get the bike upright before getting back on the throttle. Make brake, throttle and clutch movements slow and smooth. Keep speeds down so as to reduce steering input and lean angle. Posture is important and we need to try to keep weight off the handlebars. This isn’t easy on a sportsbike but sit forward on the seat, grip the tank with the knees, brace the back and keep shoulders, elbows and wrists loose.

If the bike does twitch, don’t try to fight it. There’s a reasonable chance the bike will regain grip but trying to fight the wobble just makes things worse in my experience. If we do hit ice, the most important thing is NOT to touch the brakes. It’s an incredibly strong instinct to overcome, but touch the front on a non-ABS bike and we’ll be on our ear before we know what’s happened. The rear brake will probably lock the back wheel, but we may be able to save the slide if we’re upright. Even with ABS the bike will be destabilised. I’ve been told to “steer into a slide”, but on the couple of times I’ve hit ice mid-corner, I’ve crashed so quickly I’ve had no time even to think about it.

Which gear should we ride in? The old advice was to ride in a higher gear than normal, but I suspect it works best on old bikes. It applies to 1960’s Bonnies and BMWs with low-revving, slow-revving engines. It’s entirely debatable if it should be applied to modern high-revving, fast-spinning bikes. If we ride in an artificially high gear to keep the revs low, we’ll be using more throttle than usual for the speed. Some years back on my GSX-R750, I was in too high a gear when I hit a slippery surface and the rear wheel lost traction. The bigger-than-usual throttle opening caused the engine to rev, that spun up the rear wheel, the rear back end stepped out sideways and I just avoided a high-side… at about 10mph! Counter-intuitively, a lower gear would have needed less throttle to drive the bike forward at the same speed, and so the wheelspin would have been less violent. And even if you have traction control, it’ll kick in and you’ll almost certainly shut the throttle. If you are riding an older machine that’s not so equipped, then the answer is to make your own traction control – drag the rear brake lightly right through the manoeuvre until the machine is upright again. It’s crude but it stops wheelspin… and it works. I’m not saying ride everywhere in first gear but take any advice to ride in a “higher gear than normal” with a pinch of salt if you’re not riding a Royal Enfield.

Take it easy out there, and stay shiny side up!

36. Aquaplaning – what it is and how to deal with it

Not much to say about this other than to add that tyre condition matters more than tyre type; worn centre grooves, squared-off profiles and under-inflation all seem to be factors associated with increased aquaplaning risk. far more than most riders realise whilst electronic aids Electronic aids such cannot restore grip when a tyre is floating on water. If you do detect the “light, floaty bars” don’t attempt to counter the movement aggressively; that’s a common instinctive error and will just destabilise the bike.

Aquaplaning – what it is and how to deal with it

When I originally wrote this tip almost twenty years ago, my main worry was winter weather. But in the last few years, torrential rain and standing water on summer roads has become just as common and it can be a real hazard. I don’t mean just ploughing into standing water and having the bike stop almost dead, or even finding that the puddle is actually a pothole, but the problem of aquaplaning. So this article explains “what is aquaplaning, how likely is it to happen, how do we recognise it’s happening and what do we do about it?”

Let’s start by explaining what aquaplaning is. I think the term has probably been borrowed from ship design. A ship has to push water aside in front of it, and when that vessel’s speed is sufficiently high, the water cannot get out of the way fast enough. So the vessel tends to rises up and ulimately ‘rides’ on the wave it’s created. That’s the basic principle behind high speed ferries.

Tyres do pretty much the same. When water is sufficiently deep and speed sufficiently high, the tyre cannot displace the water to the side quickly enough. A wave builds up ahead of the tyre’s contact patch and with just a bit more speed and the tyre rides up and ‘floats’ on its own bow wave. And that means it’s lost contact with the road surface, and the tyre has no braking or steering grip!

Here’s the good news. Whilst aquaplaning is quite common when driving a car – the barrel-shaped profile of a car tyre has a broad contact patch that pushes water ahead of it – a motorcycle tyre is U or V-shaped and the relatively long, thin contact patch cuts more effectively through standing water, much like a ship’s bow.

In my experience, aquaplaning is pretty rare on two wheels compared with four. In fact, if we do much motorway driving in wet weather, aquaplaning is quite common. But I can count the times it’s happened on a bike on one hand.

The danger seems to be a road surface just awash with standing water, where we we wouldn’t normally think twice about riding through it at a modest speed. It happened once near Brands Hatch, where the road is wide and flat – it’s an old concrete surface underneath the tarmac skim and so there’s no camber to clear the water, so there was standing water over a considerable length of road. The speed limit is only 40, so it seems that it’s the distance the standing water stretches that matters, rather than flat-out speed. I had a similar incident in the Ardennes in Belgium on a brand-new road that was ‘super-elevated’ – that is, cambered so that the entire road ‘banks’ for each corner. This seemed to trap the rain from a thunderstorm so that rather than flowing OFF the surface, it acted more like a channel of the water.

Hitting a short stretch of deep water doesn’t seem to create the right circumstances for aquaplaning. I suspect this is because the resistance of the water creates a sudden deceleration so there’s no chance for that wave to build. The impact will try to wrench the steering out of our grip, but it’s not aquaplaning. And, let’s face it, if we see a big puddle, it’d be a good idea to avoid it when possible, or slow down when we can’t as we’ve no idea what’s under it.

So watch out for shallow sheets of water, particularly after a thunderstorm or prolonged heavy rain. Look out for places where run-off from a field or an overflowing drain flows into the road. Motorways and dual carriageways are bad because two lane roads like A roads and country lanes normally have a crown that drains water to either side, but the carriageways on a dual carriageway are usually flat, Watch out too for standing water in truck wheel tracks. At speed, and with spray flying around, we may well not see the problem until the last second. So try to keep a good gap, and don’t go excessively quickly.

In my experience, the warning sign that the bike is aquaplaning is that it keeps going in a straight line, but the bars go light and floaty-feeling. They may even move from side to side. It’s a bit like riding on ice, but with one important difference – on ice, the first warning is often wheelspin but when aquaplaning, the rear wheel continues to drive the bike forward, presumably because the rear is often following in the trough cut by the front tyre. It’s front tyre grip that’s compromised.

If we suspect we might be aquaplaning, the best answer seems to be, as is often the case, to keep a relaxed grip on the bars – hanging on for dear life always makes things worse. Lock onto the tank with the knees to keep the weight off the bars and do nothing harsh or sudden. Once again, in my experience, if we simply roll off the throttle gently, the reduction in speed plus the extra loading at the front gets the front tyre to cut back down through the water to regain grip. But don’t apply the front brake – if it’s floating, it could lock. If it’s necessary to brake, use the rear gently. Don’t try to steer until there’s feedback through the bars telling you that the front tyre is back in contact with the road surface.

17. Staying Warm on two wheels

Physics doesn’t change. Only our understanding of the principles does. Given how long ago I wrote this article, it has not just stood up well to the passage of years, I’d venture to say that it was is quietly ahead of its time, at least in the world of motorcycling: the emphasis on core temperature, cognition and risk perception, and decision-making, rather than just comfort, aligns very closely with how cold-weather risk is framed today in both occupational safety and human-factors research. Hypothermia is insidious and often unrecognised and framing getting cold as a decision-making and control problem is crucial, and extends far beyond a comfort issue, something still under-emphasised in mainstream motorcycling advice. That reinforces why riders underestimate cold-related risk. The central insight — cold hands are a symptom of falling core temperature — is the core of the article and scientifically valid as is the explanation of insulation as rate-of-loss reduction rather than heat retention. This is a mistake riders still make even today, relying on layering too much.

Where I writing the article today, I would point out that much of my critique of heated grips is fair, but they are more reliable and somewhat more effective than the ones I struggled with back in my courier days, but they are still more useful as a supplement to heated clothing, but not a solution, particularly on a long ride.

Staying Warm on two wheels

Motorcycles and cold weather aren’t entirely compatible. Whilst the biggest winter risk to riding in the UK is ice, the subtle disorientation caused by hypothermia isn’t that far behind. The wind chill factor is considerable on a bike, and the hands are stuck out in the wind. They also have a large surface area to lose heat from, and so are the first part of the body that we notice getting cold. Unfortunately, because gloves still need to allow us to operate the controls, they are also probably the most difficult part of the body to keep warm. Over the years, I tried all sorts of ways of keeping my hands warm. I tried some pretty expensive kit as well as ideas I knocked up myself for nothing. So have a read, learn from my experience, and before you dash out and spend big cash too, don’t make the same mistakes I did.

In an attempt to keep my hands warm I’ve tried:-

thick gloves
thermal gloves
World War 2 flying gloves (really!)
skiing gloves
silk inner gloves
thermal inners
overmitts
handlebar muffs
cut down milk containers
heated inners
heated handlebar grips

But before I discuss how well they worked – or didn’t work – let’s consider just why hypothermia isn’t uncommon when riding a bike.

Heat is lost from the body by three routes:

radiation
convection
conduction

Fairly obviously, the blood flows out down our arms and legs to hands and feet, and back to the heart. But when it’s cold, the blood passing down arms and legs is cooled by the windblast – their large surfaces act as radiators – and returned to the core of the body. Now it has to be re-heated before being pumped round the body again. The body can cope with mild cooling – it just turns up the heat by burning more fuel – but there’s a limit. Once we start losing heat faster than the body’s self-warming process can cope with, we start losing heat from the body’s core. And the steeper the temperature gradient (ie, how cold it is), the faster we chill.

Now, we don’t really feel any of that, but what we feel is the next stage. As our core temperature starts to fall, the circulation of warm blood to the surface capillaries begins to shut down to reduce further heat loss. Skin feels cold to the touch. Go a stage further and the blood supply to the body’s extremities also starts to shut down – now it’s not just skin that’s cold, but our hands and feet, and eventually even our arms and legs.

What are the effects of this chilling? When are arms and legs get cold, the muscles operating our fingers, hands and feet become stiff and unresponsive. And we start to struggle to control the bike. I remember one icy ride from London to Kent when I couldn’t actually change gear for the last ten minutes.

That’s bad enough, but it gets worse. We also lose heat through our neck and head, and that means the brain is affected too. We start losing focus and making bad decisions.

So that’s hypothermia. And it sets in surprisingly easily on a bike. If you’ve ever reached the stage of shivering uncontrollably, you’re in the early stages of hypothermia. . This is not idle speculation – this comes straight from sports physiology research.

So what was the mistake I made? It’s pretty obvious when you read the list above – they were all attempts to keep my hands warm. Unfortunately, that’s treating the SYMPTOMS rather than the DISEASE.

Let’s just recall what thermally-insulated clothing does. We think of it as ‘retaining’ heat, but that’s not actually how it works. It SLOWS DOWN the rate of heat loss.

So here are two points to think about:

thermal insulation only works up to the point where the temperature gradient across the insulation is steep enough for the rate of heat loss to exceed the body’s ability to heat itself. Once temperatures dip low enough, from that point on, we are going to chill. For clothing with good thermal insulation, that threshold temperature is lower.

if we only ride short distances, thermal insulation may slow down the rate of heat less enough that we don’t notice the chilling effect of cold weather. But on a longer ride in the same clothing, we will continue to lose heat for as long as we’re riding, and then all that our thermal clothing can do, no matter how good it is, is to delay the onset of chilling. It prolongs the agony, as it were. This is a serious problem if you are habitually a short distance rider and suddenly do a long trip. It took me years to understand why the clothing that kept me nice and warm on short rides let me get so cold on long runs.

So the key point is that whilst moderately chilly weather may be tolerable for short rides, as soon as the temperature really dips or we take a long ride, we’re going to chill. Circulation to the arms, legs and brain are all reduced, and eventually we’ll lose our mental focus too.

One obvious solution is to keep adding thermal insulation until we stay toasty. That’s the idea behind ‘layering’. But after a bit, thick gloves with inners get too bulky to be easy to use, and we end up looking like the Michelin Man – try looking over your shoulder!

So let’s step backwards a bit, and recall that if we keep the core temperture high, blood keeps circulating. But how can we supplement the body’s own ability to supply enough extra heat?

Well, the obvious solution if hands are cold is to use something to heat the hands – heated grips and gloves . But remember – this is the symptom, not the disease. They might make our fingers feel warm but they are very inefficient – most of the heat produced is lost again, either by conduction down the metal bars or radiation from the back of the glove. My experience is that I still got physically cold even if my fingers felt warm, probably because the warm fingers ‘fool’ the brain into opening up capillaries to blood flow, which then loses heat. And as a secondary problem, I’ve found heated grips and gloves fail very quickly because of the constant flexing. I generally reckoned on a year for heated grips before the wiring failed and one winter for the gloves, sometimes just a couple of months. It’s the heating elements that go in gloves and the feed wire on the throttle side with grips.

So can we heat the core directly? We can, by using heated clothing. A heated jacket or waistcoat adds heat where it’s needed, and given the same insulation, the result is that we push the point where we start to chill to a lower temperature. With core temperature maintained, so is circulation to the extremities and so hands and feet get a constant supply of warm blood.

In my experience of riding through really cold weather – I was a blood runner for several years, being called out at all hours of the night including in mid-winter – a heated waistcoat may not completely overcome the cooling effect but goes a long way towards it – on one 3am ride in January when it was -10c, my fingers still got cold but they didn’t go numb. I would have struggled to complete the ride without the waistcoat. I’ve found that if it’s chilly (10 – 5C) wearing a long-sleeved shirt, a light fleece then my heated waistcoat keeps me warm. If it’s cold (around 0) I wear the fleece over the waistcoatr. Below zero, I put unlined waterproofs over my riding suit, and that is sufficient to deal with a three hour riding down to about -10C.

Heated waistcoats are available for around £100 and my experience is also that they last much longer. My first Gerbing waistcoat lasted a decade, and my replacement from Exo2 is even older. Only the oldest bikes will have problems with a waistcoat – they draw no more than about 30 watts – half a halogen headlight bulb. It’s also possible to daisy-chain heated gloves, socks, leggings and collars from some manufacturers, but make sure your bike’s alternator can cope with all that lot.

Personally, I’d avoid a heated jacket. You can wear a heated waistcoat under several layers of insulation BEFORE putting a jacket on – you can’t do this if the heating element is built in to the jacket.

Final tip – plug the leaks! Keep wind out of your clothing by tightening wrist straps, using a scarf or neckwarmer and zipping jackets to trousers or wearing one-piece suits. Several thin layers are better than one thick one, unless it is a fleece – the idea is to trap air and stop it moving. If you have a separate jacket, bib-and-brace type trousers help keep the kidneys warm. A cheap one piece rain suit over the top will do wonders if you have separate jacket and jeans.

And a word of warning – don’t put the heated waistcoat next to the skin – the heating element can get pretty hot and you will end up looking like you barbecued yourself! You can get inline temperture controllers, or just wire in a simple on-off switch on the bike’s dash. Don’t forget to fit an inline fuse to avoid self-immolation.

If you want to stay warm on a bike this winter, spend some smart money on a heated waistcoat!
