It’s the fourth article in the ‘Core Skills’ series, where I return to the essential riding foundations and rebuild them from the ground up in a fresh way, using a brand-new structure too. Today it’s time for a Fresh Start look at balance.
#freshstart, #coreskills
THE MYTH — “Balance is only for Mod 1 cones.”
Something I have (slowly) come to realise as a rider coach is that thanks to the focus on slow riding as a discreet exercise — for example, as a way to master the Figure of Eight, U‑turn, slalom and slow ride elements on the Module One part of the current UK motorcycle test — it means many riders treat the concept of balance on two wheels as something that only matters at low speed. This unintentionally creates the impression that slow riding is a special technique used only for “riding round the cones” and riders treat slow control as unrelated to ‘normal’ riding, forgetting that it is simply the far end of a balance continuum.
The result is not so much a difficulty with the slow‑speed exercises themselves, since the vast majority of riders learn the necessary techniques to negotiate the test manoeuvres, but a lack of understanding as to why the bike behaves differently at different speeds.
Understanding the theory of motorcycle balance is crucial to the practical application of the skills needed for slow speed control but so is the need to recognise that as speed drops motorcycle moves along a continuum from passive balance (where the machine balances itself) to active balance at low speed — and that it is the transition between the two that causes most riders problems.
THE MECHANISM — “The Stability Handover: From Physics to Pilot.”
Unlike a car or a bicycle fitted with training wheels, a motorcycle has no ‘static’ stability, it cannot remain upright without support from the rider’s leg or a stand — what happens if this support goes missing is referred to as the ‘capsize mode’. But quite obviously once the machine is rolling riders can keep it upright, but just how this ‘dynamic’ support happens still confuses quite a few riders:
1. Some believe that the balancing mechanism is always the rider, who has to constantly steer the front wheel from side to side to maintain balance once the bike is in motion. In fact, this is what I believed when I started riding back in the 1970s.
2. Others hold that gyroscopic force is the sole reason a bike stays upright. I heard that theory a couple of years into my riding career. While spinning wheels do provide some stability, and precession will make a wheel that is turned lean at the same time, it’s not the main mechanism keeping a bike upright.
In fact, understanding balance requires accepting that there is not one single mechanism that keeps a moving motorcycle balanced. In fact, it’s a system that undergoes a fundamental ‘personality shift’ based on velocity.
1. At Speed: Passive Stability
— as speed rises, a typical modern motorcycle begins to exhibit strong self-stabilising behaviour. There is no ‘fixed threshold’ for this transition but as a practical rule of thumb it tends to happen above approximately 15 mph (25 km/h). The transition is gradual rather than absolute. Through a combination of gyroscopic inertia and steering geometry the bike wants to stay upright. If it leans left, the front wheel automatically steers left just enough to move the tyres back under the centre of mass. As speeds increases, what does most of the work in keeping a motorcycle upright is ‘coupled dynamics’:
i. forward velocity
ii. steering geometry (trail, head angle)
iii. mass distribution
iv. tyre lateral force characteristics
The usual example is the humble shopping trolley wheel; it’s designed to follow the direction of travel. On a moving motorcycle, if the bike leans slightly to the left, the geometry of the front fork interacting with tyre forces naturally turn the handlebars into that lean. This ‘self-steer’ effect moves the tyres back underneath the leaning weight, effectively catching the bike before it falls. At speed, the bike is essentially continually self-correcting without you even noticing. The rider doesn’t ‘balance’ the bike, just steers it where they want to go. I’d be the first to admit that some of the bikes I rode in the 1970s and early 80s were less than stable in some circumstances, exhibiting what are termed ‘wobble and weave’. But the appearance of radial tyres around 1983 forced manufacturers to work harder on chassis design through the 1980s, the modern motorcycle with reliable handling emerged. This allows the modern motorcycle to maintain straight‑line balance over a wide speed range with minimal — even no rider input — at normal riding speeds, and to recover from being destabilised by minor bumps or light gusts of wind. It’s possible to ride hands-off. The effects of wobble and weave are minimised.
2. Intermediate Speed: The Grey ‘transition’ Zone
— as the bike slows down, there’s no sudden ‘cut-off point’ where the bike loses all stability. Instead, the passive stabilising effects we feel at speed diminish progressively and the machine transitions along a continuum from predominantly self‑stabilising behaviour to a state in which the rider must actively balance the motorcycle through timely steering inputs. The rider feels this as the zone where the bike’s stability falls away as the machine itself provides steadily less resistance to tipping.
3. Low Speed: Active Balancing
— from around 5 mph / 8 km/h and below, passive stability decays progressively. The motorcycle is now an unstable system that will fall over unless the rider intervenes. This is where balance becomes active. You must now manually perform the task the bike was doing for itself at 50 mph: maintain balance through continuous steering inputs, turning the front wheel into the fall to bring the contact patch back under the weight of the bike. This process is continuous, which is why slow riding involves a series of small, frequent steering corrections rather than a straight line.
How accurate are the figures? It’s not possible to be exact, since it’s dependent on the specific machine’s design, but studies by motorcycle engineers like Vittore Cossalter (author of Motorcycle Dynamics) provide estimates for modern machines.
Is this ‘new’ knowledge? Actually no. Francis Whipple was a British mathematician and meteorologist who, as an undergraduate at Trinity College, Cambridge, provided the first formal mathematical proof that a moving bicycle could be self-stable. As long ago as 1899, Whipple showed that if a bike has the right geometry (like rake and trail), it will automatically steer into a lean, which drives the wheels back under the centre of mass. He proved that depending on speed and machine configuration, a bike is mathematically capable of balancing itself. Below that range, it is unstable (capsize mode) and above it, it can become unstable again (wobble and weave modes)
The only reason that I can think of for the belief that a motorcycle was inherently unstable, and that the rider had to continually steer the front wheel from one side to the other to create a kind of ‘virtual instantaneous tripod, that was prevalent when I started riding in the mid-70s is that the machines had less advanced tyres and chassis design, and often exhibited more pronounced instability.
THE MISTAKE — “Riding too slowly.”
When space is tight, many riders respond to the growing instability by slowing down even further. In theory, at any particular lean angle, riding more slowly means a tighter turn. It sounds like the obvious solution to manoeuvering in a confined area but since riding ever-more slowly reduces the machine’s passive stability and forces the rider to actively balance it with steering and posture inputs, control becomes ever more difficult and reaches the point where large and coarse steering corrections are needed. As a result, all but the very best riders discover they need more space to stay upright when riding too slowly — which hardly solves the problem when the available space is already limited. Two common situations illustrate this clearly:
1. Slow‑moving traffic
Trying to creep along at slow‑walking pace forces the rider to balance an unstable machine while making constant steering corrections. It is usually easier — and more stable — to stop, let a gap open, then move forward smoothly before stopping again. Each short movement is made at a speed where the bike has some passive stability.
2. Tight turns in confined spaces
The instinct is to slow right down, but this removes stability and forces the rider to use large, late steering corrections. A better approach is to maintain a slightly higher, steady trickle of speed — just enough for the bike to regain some self‑stabilising behaviour — and then lean the bike more to tighten the turn at the higher speed. It feels counter‑intuitive, but it works because the machine is easier to balance when it is moving a little faster.
A related issue is poor posture. Posture will be covered in detail in another article in this series but it matters here because poor posture makes control more difficult at any speed, but at low speed it magnifies the consequences of any instability the rider introduces.

THE METHOD — “Recognise the Continuum and Transition Smoothly.”
Since passive and active balance sit at opposite ends of the same balance continuum, the real skill is transitioning smoothly between the two.
1. Accelerating: the easy transition — when pulling away, the transition is straightforward. There is a brief moment where the motorcycle is dynamically unstable, but this period is short and even novices rarely struggle because as speed increases, the steering geometry and tyre forces gain authority, the bike quickly develops strong self-stabilising behaviour, and the rider feels the machine ‘come alive’ and balance itself.
2. Decelerating: the more tricky transition — the difficulties appear when speed is reducing. As the motorcycle slows, passive stability fades and the rider must take over the balancing task, using active steering and posture corrections. A smooth handover — from the bike doing most of the stabilising to the rider taking primary control of balance — is what makes low‑speed control predictable and repeatable when performed to a reasonable level of skill, and so unpredictable for those riders who don’t understand the mechanisms involved.
Here is a repeatable, road‑relevant control strategy for slow‑speed control that works everywhere: Mod 1, mini‑roundabouts, hairpins, tight junctions, loaded touring bikes, two‑up riding.
1. Set the controls up: Before practising slow control, ensure the clutch and brake levers are correctly adjusted and within easy reach. Fine control of the clutch and rear brake depends on lever position, and poor setup forces tension into the arms and shoulders — exactly what destabilises the bike at low speed.
2. Posture: Brace the body, free the bars. Slow control begins with how you sit on the bike. Sit forward up to the tank, knees braced against its sides, and shoulders and elbows loose, and make a conscious effort not to lean on the bars. This “brace position” stabilises your torso so your arms can stay relaxed — essential for steering. As soon as the bike is moving, get your feet on the pegs. Dangling feet remove the brace position, load the bars and destabilise the steering. And keep your eyes looking where you want to go next.
3. Drive through the active balance zone: If you’re moving off, simply ease the clutch out as the throttle rolls on and accelerate into the passive stability zone.
4. Slow through the active balance zone to a stop: When it’s time to stop, roll off the throttle smoothly, gently apply the rear brake to progressively bring the bike to a halt, pulling in the clutch just before the bike stops. Aim to stop with the left leg down because that allows you to keep the right foot on the rear brake.
5. If you have to ride slowly: Clutch + throttle + rear brake is the key to slow control. Slipping the clutch in the ‘friction zone’ breaks the direct connection between engine and rear wheel, preventing bumps or small throttle twitches from causing sudden surges that destabilise the bike. Hold a steady, slightly elevated throttle to keep the bike under drive, then control speed with the rear brake, not the clutch. Keep the ball of the foot on the brake, and it’s best to keep fingers OFF the front brake since a temptation to use it risks upsetting balance. It’s the rear brake that allows fine speed control without destabilising the bike by causing the forks to dive.
6. If you’re going to turn: Move away upright and get ROLLING in a straight line to gain balance, THEN turn. It’s a lot easier than trying to turn directly from a standstill because the straight line pull-away gives the bike the stability it needs before you ask it to lean. Even at low speeds, a small counter-steering input will lean the bike into the turn. To get the bike to turn tighter without slowing, use ‘counterweighting’ by letting the bike lean ‘in’ to the corner while keeping your body upright. Bend at the waist, shift your shoulders to the outside, and twist your torso so your shoulders and arms align with the turned bars. Counterweighting shifts the rider’s mass to the outside, allowing the bike’s mass to move inward, which forces the machine to lean further. The greater lean tightens the turn without decreasing speed. Remember to keep the right foot on the rear brake — if you’re turning and the road slopes downwards, the bike will tend to pick up speed. Now is a bad time for a handful of front brake.
7. Vision: Know the point you want to reach, then search for it: Don’t stare at hazards like a kerb or parked car. Instead pick a positive reference point on inside the turn — it can be a different coloured patch of tarmac, a white centre line marking, even a leaf. This gives you a target to ‘steer around’ rather than a ‘fixation’ to distract you.
8. Progressive Skills Building: Start by practising transitioning between slow control, normal riding and back into slow control in a straight line. Accelerate to a stable speed, then roll off the throttle, slow with both brakes, release the front brake as you enter slow control, stabilise with clutch + throttle + rear brake, then stop smoothly on the rear brake alone. This builds the essential skill of re‑entering active balance without tension or instability. Having mastered that, try riding slowly in a straight line using the clutch + throttle + rear brake approach. To practice slow turns, the best exercise is the Figure 8. Start big and wide, and slowly tighten the Figure 8 and introduce counterweighting. Finally introduce U‑turns.
Each layer here reinforces the last. Remember; as speed rises, steering inputs become smaller and less involved in balance correction and as speed falls increased steering involvement and actively manage balance. This smooth handover — from the bike balancing you to you balancing the bike — is what makes low‑speed control predictable and repeatable.
THE MINDSET — “Expect the Transition, Don’t Fight It.”
Accept that the behaviour of the motorcycle changes with speed and expect the transition from passive to active balance, recognise it early, learn to manage it so it becomes routine rather than something you react to. Stay relaxed, and treat low‑speed balance as a normal part of riding — not a special trick.
THE MARGIN — “Create time.”
The final part of good slow‑speed control is leaving yourself enough time to cope. That means creating time for the transition from passive to active balance, and time to apply the necessary slow‑control skills once you’re in the low‑speed zone.
It works in both directions. Setting yourself up early as you decelerate gives you the space to take over the balancing task cleanly, before passive stability has reduced significantly. Leave it too late, and you are trying to manage both the loss of stability and the external hazards — tight junctions, mini-roundabouts, hairpins — at the same time.
In either case, the enemy is being rushed. When riders arrive late to the transition or late to the hazard, they end up reacting rather than managing, making larger and later steering corrections. Compromised slow control is unforgiving, so make time to allow balance changes to unfold slowly enough to be controlled.
