Hairpins are just a type of corner. True, they go on longer than other bends, and they usually involve a gradient change, but the essentials remain the same. Nevertheless, they throw many riders off their game. The article provides a practical, step-by-step guide, integrating uphill and downhill considerations, braking, throttle control, line choice, and slow-speed balance.
Dealing with hairpins
Whilst we have a lot of interesting technically tricky roads in southern England, a road feature that few of us are likely to experience until we visit Europe is a hairpin bend. In an example of how demand creates supply, after a number of emails asking for help with dealing with hairpin bends, I wrote first of all this article, then put together some routes that include hairpins for practical training purposes. Though there are hairpins in the more rugged parts of the UK, you might be surprised to know that I’ve found ‘secret’ hairpins for my advanced rider training courses in Buckinghamshire, Oxford, Kent and Surrey. Aside from the London-based course, the only location I’ve not yet found a hairpin – and I doubt I will – is Essex. Surprise, that! And of course, I also know a few for my courses in mid-Wales. So if you want a practical follow up to reading the article, I will cover hairpins on my Performance: SPORT two-day course, but can also offer a short two-hour Basics: HAIRPINS course. Hairpins are great fun to ride but can also become a real problem area if we don’t plan how to deal with them.
So, “how should I deal with a hairpin bend?”.
The broad answer is “in the same way as any other corner”. After all, the elements that make up a hairpin – ‘entry’, ‘turn-in’ and ‘exit’ – are common to all corners. A good starting point – once again – is to apply the standard Survival Skills approach, and to understand how, where and why we might make a mess of them. Once we understand that, it’s not difficult to apply the ‘reference point’ approach and my standard ‘Point and Squirt’ cornering technique to any hairpin.
So where to start?
As mentioned, just like any other bend a hairpin has:
- a way in – the ‘entry’ to the corner where we have to steer or run off the road
- a way out – the ‘exit’ where we’re upright again and headed for the next bend
And we can make the standard cornering mistake on hairpin; if we turn in too early then we run wide later.
So you should already have have had a lightbulb moment about the most common problem. The most significant difference between a hairpin and an ‘average’ corner is that the hairpin just goes on a lot longer than normal. Just as on ‘ordinary’ bends, if we ‘turn-in’ too soon, we are guaranteed to run wide on the other side of the hairpin, but with the added problem that if we run wide when we’re on the outside of the corner, we’re unlikely to end up in a hedge but hit a wall of rock or drop over a cliff. The latter is the uniquely scary factor on a mountain road.
But there’s a second problem. A hairpin is – by definition – on a hill. So we’re either cornering uphill or downhill. It all sounds very obvious but unless we’re used to tight corners on hills, we tend to get the balance and timing of our deceleration and throttle inputs in a mess.
And hairpins are often fairly tight so can demand the same sort of slow approach and control we’d apply turning left or right into a junction. If we get the braking / throttle timing wrong AND get on the wrong line AND make a mess of our slow control, we’ve often succeeded in destabilising the bike right in the most awkward part of the corner.
Yet there’s NOTHING about a hairpin bend that should frighten even a CBT trainee, except perhaps the height. (I suffer a bit from vertigo, so I’m in full sympathy with anyone who gets disoriented by looking a 100 metre sheer drop off the edge of the road.)
Mental issues aside, from a technical point of view, what’s a hairpin but a kind of U-turn?
The only significant difference is that we ride into it from speed, rather than start from a standstill (so we need to brake first), and that we accelerate out again rather than come to a standstill (so we need to twist the throttle), but everything else is standard U-turn technique:
- bracing the knees against the tank to maintain a good posture, keeping the upper body loose, avoiding leaning on the tank, and having loose shoulder and neck so we can turn our head easily
- slipping the clutch and balancing the forward drive against the rear brake
- looking as far around the turn as possible
- using a counter-steering ‘nudge’ to initiate lean into the turn
- using counterweighting to keep the line tight whilst maintaining enough speed for balance
- getting the bike upright again at the end of the turn
Let’s break down what we need to achieve stage by stage, and here’s a bit of good news. Unless we already live on top of a mountain, we’ll have to go up before we come down again, so the uphill hairpins give us a chance to practice before we come to the more awkward downhill ones. A second bit of good news it’s unlikely (except in wooded areas) that we cannot see the hairpin coming from some distance. Abroad, make sure you know what the sign for a hairpin is too, just in case it’s not so easy to spot.
As with any corner, the first requirement is to match speed to the radius of the bend ahead, with a bit in hand in case it’s tighter than it looks (or we can see).
- Get into position for the turn itself. Just like any other bend, we use a wide approach but here’s my first tip. On the OUTSIDE of the turn (and even if your more experience mate is “showing the lines”) DON’T RIDE RIGHT TO THE EDGE. If we’re on the edge of a sheer drop, our mental focus is on staying ON the road. A couple of metres IN from the edge takes a lot of that pressure off. If we’re on the inside of the turn, using all the road is safer but we do need to watch for other vehicles (and I’ll come back to that in a moment.
Here’s my second tip.
- Once in position, DECELERATE EARLY. Don’t rush up to the bend and brake at the last moment even if your more experienced mate ahead of you is doing that. Slowing early really is a key point. If we’ve sorted our speed early, we won’t be worrying about running out of road, and that means we have the mental freedom to drag our eyes away from the sheer drop and look up and around the curve to see where the hairpin takes us. We need a full turn of the head to do this, so we don’t want to be look round and up the hill just as we’re trying to steer. If the terrain is open, we’ll get an overview of how sharp and steep the turn is, and whether any vehicles are on the way down to meet us at the hairpin – more on that in a moment too.
Third tip.
- Get into a low gear in plenty of time whilst still upright. Second gear is usually right on the wider hairpins, but it may be necessary to select first on really tight, steep corners. But DON’T OVERRELY ON ENGINE BRAKING – even going uphill, we’ll probably need to bring the speed right down so I’d advice using both brakes even if it’s only lightly. There’s a second reason – we’re going to need the rear brake in a moment and it’s far easier to remember to have a foot on the pedal if we’ve applied both brakes on the way up. And there’s a third reason – it’s good practice for downhill.
The fourth tip is this:
- get off the brakes and ON THE THROTTLE whilst still upright. We’re going to need the power to drive us round the bend against the slope.
Now we’ve got the speed right, and we’re about to turn into the hairpin itself. Fifth tip:
- Remember all those U-turns you did on basic training? It’s EXACTLY THE SAME MANOEUVRE, just uphill! Slip the clutch on the really tight ones and remember, the REAR BRAKE balances the THROTTLE to fine-tune our speed just as when we practiced slow control round the cones. With the rear brake ready to control the speed, come off the front brake, look right round the turn, and drive the bike uphill with the throttle.
Sixth tip.
- Apply a counter-steering ‘nudge’ to get the bike to lean and then use counterweighting (where the rider sits UPRIGHT and pushes the bike DOWN) to help maintain speed around the corner itself – don’t try to ride too slowly or the machine will start to wobble. To get the bike to turn tighter, it’s tempting to ride ever-slower. But there’s a point at which any machine ceases to balance itself, and from then on, we’ll struggle to hold any kind of a controlled line. So to keep a tight line on a hairpin, use counterweighting. We lean the machine IN, but keep our body UPRIGHT. The bike’s extra lean has the effect of needing less space to turn but at the same speed.
So that sets us up ready for the most complicated part of the hairpin – it’s halfway round which is nearly always the steepest part of the turn, and most pronounced on the inside of the corner. This is where the engine is likely to bog down if we’re not driving it against the rear brake. If we are holding the bike on the rear brake, we simply ease the brake off to add drive. But be ready – as the bike comes out of the steepest part of the turn, we will need to ease the brake on again to stop the machine picking up speed and running wide. Once upright AND ONLY WHEN UPRIGHT do we ease off the rear brake and accelerate away up the hill.
So the rear brake turns out to be vital to the slow control needed to negotiate an uphill hairpin. For many riders, this use of the rear brake is the missing link.
Here’s the seventh tip.
- In the wrong gear? Don’t try to change gear mid-hairpin because the bike will stop dead and fall over. Instead, slip the clutch – and you CAN slip the clutch in top gear if you have to.
The other common error is to try to ’round out’ the corner with a mid-corner apex and a sweeping line that maximises the radius. The trouble is, even a minor error will have us running wide on the exit, and that’s not great news if there’s a sheer drop under the front wheel. So the eighth tip is that we MUST avoid cutting into the corner too early:
- So under power, stay on the WIDE LINE until we can see BOTH SIDES of the stretch of road leading away from the hairpin. This is our ‘turn-in’ point, where (if clear) we CAN cut across to straighten out the final part of the corner. As I said earlier, it’s exactly the same technique as we’d use on any other blind corner. And if we do encounter another vehicle coming down as we go round, keeping wide is much safer. The deep-in, late-turn ‘Point and Squirt’ line I teach on my Survival Skills advanced motorcycle riding courses absolutely works on a hairpin.
Once we’ve solved uphill hairpins and understood the need to drive the bike right round the turn, but NOT to try to accelerate too early, then suddenly downhill hairpins make more sense too. It’s the same approach. Once again, it’s all about making sure we give ourselves plenty of time to pick our line, set our speed, get the bike turning tight whilst using the rear brake to stop the bike picking up speed and running wide. Rather oddly, it’s going downhill for some reason causes a lot of riders to be very tentative with the brakes. But there’s no run-off on the average hairpin so it’s absolutely vital we are confident to get our speed off because downhill hairpins are all about ‘slow in’.
Whilst there’s nothing wrong with keeping the bike in a low gear, we MUST have sufficient confidence to use the brakes to set our speed. Even if you’re riding a BMW GS with a shed-load of engine braking, once the throttle’s shut there’s no more engine braking left. But even if the brakes are only on lightly, it’s now easy to fine-tune our approach speed, because it’s easy to misjudge deceleration downhill, thanks to gravity.
And don’t forget, whilst gravity also pulls us down around the corner itself, if we were using both brakes down the hill it’s much easier to remember to keep a foot on the rear brake to control our speed round the tightest part of the corner. Just as we did when going uphill, don’t release the rear brake until the bike is all the way round and upright again – let it off too soon and the bike WILL pick up speed and start to run wide. Once again, slip the clutch if needed on a really tight turn but don’t coast round.
Here are tips nine to thirteen:
- whether up or down, try to minimise gear changes between hairpins. It’s less thing to worry about and if we let the engine rev we’ll get good drive up and good engine braking down
- if we have a clear view and other traffic allows, we can cross to the ‘wrong’ side of the centre line to open out the hairpin where it’s really tight, and then pull our line back onto our own side as we exit the bend – it’s better than turning-in too tight and running wide later
- coaches and lorries coming the other way will to need a lot of road to get round the hairpin – if the road’s narrow, it may be best to stop short and let it complete the turn first rather than to try to compete for space
- if we’re being tailgated by another vehicle through the bends, back off on a straight and let the driver pass
- remember we’re dealing with bends. That means polished surfaces, rippled tarmac and fuel spills. After rain (or snow) expect water to run across the hairpin, and watch out for gravel or stone chips torn out of the surface
And tips fourteen to seventeen help if you’re riding in a group:
- ride at YOUR pace, not the leader’s or the rider ahead
- leave sufficient space so that you can look around and see where the road goes, whilst leaving plenty of space in case they make a mess of it
- don’t follow the rider in front, and let them get far enough ahead so that they are not a distraction, hold back and let them finish the hairpin before you get there
- don’t copy the rider ahead but ride your own ride. If you rely on them the guy ahead to get it right and they don’t, so will you.
Eighteen, nineteen and twenty:
- understand that if we are nervous about hairpins, getting the first few wrong will make us REALLY nervous about the rest of them. That means tenseness, and tenseness destroys control. Take the time to get the first ones right.
- we’re heading to the mountains, it’s a very good idea (tip nineteen) to practice a slightly different style of U-turn – ride into them from speed so braking is necessary, and leave them by accelerating away. I use a ‘box’ exercise to help with this. That way we can build in some practice BEFORE we leave.
- don’t forget that building ANY SKILL RIDING SOLO is NOT the same when riding TWO-UP, particularly when it’s loaded with gear – the bike WILL respond differently loaded and the best time to discover this is in Tesco’s car park, not as we hit the first downhill hairpin and wonder why we’re struggling with the turn.
Working your way through those should help you prepare for your first experience of the hairpin bend.
