What Causes Speed To Change How You Steer A Motorcycle
I of the greatest tools a motorcycle passenger possesses is the operational technique of "push steering". Too referred to as "counter-steering", "positive steering", or "gyroscopic steering", this manoeuvre is essential and a must for ultimate control on whatsoever single track vehicle – a motorcycle.
There are several primal uses for push steering when decision-making your motorcycle. It's a lifesaver when used in the emergency procedure – "swerving" – to avoid standoff or objects on the road. It'southward also a technique you will use on daily rides for performing sharp turns and navigating corners – deadening or fast. Every bit when push steering is proficient in functioning, it can assist you lot control rear bike slippage in a corner.
Bottom line, leaning the motorcycle is the manner to make it turn and push steering ensures this happens.
Though some rider grooming coaches exclaim that a motorcyclist "naturally" perform push button steering when riding a motorcycle, this is non the case at all. It must exist learned. Push button steering is an essential skill that needs to exist mastered and performed without thinking.
More common than non, motorcycle accidents and mishaps occur due to the passenger steering into the object they're trying to avoid. This is a direct consequence of the rider non comprehending push steering and the ability to implement it.
In the over 38 years I've been instructing riders on the method of push steering, I've utilised various methods to get individuals over the mental roadblocks that forestall them from performing it. It's a heed bough. When a rider is told to "push right to become right, and push left to become left" the brain only wants to resist. Commonly when button steering is first introduced, and explained – information technology is not just hard to believe – only likewise trust that the technique actually works.
Therefore, the very first step is to sympathise the instruction and then just do information technology. In one case the manoeuvre has been felt it volition then exist easier to finesse and master information technology.
WHAT IS PUSH STEERING A Motorcycle?
Push steering is a push forward (or forward force per unit area) applied to your handlebars, at speed. This applies to all handlebars and all single-track vehicles, even a bicycle.
NOTE: This technique does not utilise to conventional multiple-tracked vehicles with three or 4 wheels such as trikes, side-car motorcycles, Tin-Am Spyder models, or Polaris Slingshot vehicles. I echo, it only applies to a "single-rails" vehicle.
And then here's the brain-training:
►Push button forrad on your LEFT handlebar to get LEFT.
►Push forward on your RIGHT handlebar to go Correct.
This is the brain drill echo:
►Push LEFT go LEFT, push RIGHT go Correct.
Repeat this mantra over and over again in your listen.

It'southward the blazon of push button y'all'd use to push open up a door i.e. a revolving door. And while pushing forward, naught changes in speed, gearing or your grip to the handlebars.
We know as we proceeds speed on a motorbike something chosen "gyroscopic inertia" kicks in. This is characteristic once more, of a single-runway vehicle where the inertia (speed/ acceleration) results in the motorcycle standing up and when inertia is reduced, causes it to fall or become hard to balance. Inertia, this forwards forcefulness indeed presents its challenges in a corner, or plough equally you might imagine – the motorcycle wants to remain standing upwards – to go straight. To make this piece of work we need to interrupt this forward moving ability to create a lean, resulting in a plough – button steering.
WHAT Actually HAPPENS WHEN YOU Push?
Push steering interrupts inertia (forward moving power). This gyroscopic inertia is the outcome created by riding a "single track" vehicle as mentioned earlier. You lot and the motorbike must offset exist leaned in the management of the turn, and steering briefly in the reverse direction to cause the lean.
Accept cornering for case. Push steering works by combining the motorcycle and rider's center of mass (or centre of gravity) to exist leaned in the direction of the turn. Push steering briefly in the contrary direction causes that suspension resulting in a lean.
On that point we need to acknowledge the push power or "steering torque" and steering angle necessary to found the lean. Then we need to sustain the push and the steering angle to maintain a constant radius and lean bending until information technology is time to exit the turn. The initial "steer torque" or push and steer angle are both opposite the desired plough direction. The sustained steer bending is usually in the same direction as the turn, but may remain contrary to the direction of the plow, peculiarly at high speeds. The sustained steer torque (push button) required to maintain that steer angle is usually opposite the turn management. The actual magnitude and orientation of both the sustained steer angle and sustained steer torque of a particular cycle in a particular turn depend on: forward speed, cycle geometry, tire properties, and combined bike and rider mass distribution. Whew!
STEP BY STEP + SOME PHYSICS
Let'south get through the steps of wanting to steer our motorcycle left – a left push button steer.
- Nosotros use forward pressure (a push to the left handlebar). The effect of the "push force" interrupts the motorcycle's turning move (inertia) and causes the forepart bike in its rotation, to turn right. This occurs apace and is rather unseen or undetected.
- The front tire will generate forces to the right.
- The motorcycle "car" equally a whole steers to the right briefly.
- The rear tire too generates forces to the correct.
- Because this forcefulness is applied at "ground zero", this pulls the wheels "out from under" the mass. Gravitational force steers the motorbike to its correct.
- The resulting roll bending to the left causes the tires to generate "camber thrust". (Camber force are terms used to depict the force generated perpendicular to the direction of travel of a rolling tyre due to its camber angle and finite contact patch). The left providing the centripetal "force that makes a body follow a curved path"- forces required to plough left.
- The geometry of our motorcycle's steering system provides the forces needed for our front wheel to prefer an angle turned into the plow in a predictable way.
- The motorcycle goes left!
WHAT'S ALL THIS MASS STUFF?
The eye mass of a body, in our instance, is the motorcycle. The big engine mounted mid section is where the unabridged mass, your motorcycle's body, is concentrated. It'south mutual to refer to this also every bit the motorcycle'south "centre of gravity". This is considering the weight of a body (the motorcycle) acts every bit if it were full-bodied there in a uniform gravitational field. Information technology's rather rigid torso, the centre of mass is fixed in relation to the trunk.
Generally speaking, the mass middle obeys elementary equations of movement. That's physics again and applications such equally – "push button steering".
It works considering the handlebar section is non the inert mass. That'southward the engine expanse; the surface area you're usually sitting on or over. And for any organization with no external forces, the centre of mass moves with constant velocity.
Have YOU EVER FRIGHTENED YOURSELF WHILE CORNERING?
It'due south important to distinguish betwixt:
- push button steering equally a physical occurrence and;
- push steering equally a witting passenger technique to your initiation of a lean.
The physical occurrence happens because there is no other way to cause the bike and rider to lean. Nevertheless absolutely in corners, where everyone seems to complain of fear and anxiety, you lot'll need to brand the witting try of pushing. At lower speeds such as at 10km per hour (walking speed), inertia is absent and you lot'll exist able to turn your motorcycle by steering or turning the handlebars – simply as you exercise on your bicycle.
Many riders can get past without knowing push steering by shifting body weight in something called a counter-lean. Withal, documented physical experimentation shows that on heavy bikes shifting body weight is of petty result and has no guarantee at initiating leans. This is further evident in higher speeds i.e. motorcycle racing. Your trunk weight is no lucifer for the inertia generated.
MORE Push button STEERING FAQS
THAT'Due south HOW WE Coil. Motorcycles steer past controlling "roll" bending. However, roll[ing] angle is not directly manipulated by the handlebars in the same way every bit steer bending in an automobile by the steering cycle. It is influenced indirectly past applying "gyre moments" to the machine. These roll moments in turn come from side forces at the wheels, which are closely related to steering torques (pushes). Thus the bike is a "force-controlled" organisation in which the actual position of the handlebars is free. Slant thrust is how we lean. The lean of a bike'south wheels causes a turning force in the management of the lean. Camber thrust enables the bike to negotiate turns with substantially less steering angle of the forepart cycle than an automobile for the same turn radius.
WILL I Autumn OVER?A unmarried-track vehicle such as a bicycle or a motorcycle is an inverted pendulum. It will fall over unless balanced.
Can SHIFTING WEIGHT OFF THE MOTORCYCLE MAKE THE BIKE TURN? It is frequently claimed that 2-wheeled vehicles can exist steered using just weight shifts. While this is true for small inputs to direction (i.e. when trail riding, weighting the pegs to turn in off-roading, etc.), complex manoeuvres are not possible using weight shifting alone considering even for a light automobile, there is insufficient command authority. Although on a sufficiently light cycle (especially a wheel), the passenger tin can initiate a lean and turn by shifting trunk weight, there is no evidence that complex manoeuvres can exist performed past torso weight alone.
Tin I Practice THIS IN THE RAIN OR ON A Slippery SURFACE? Push steering a motorcycle has best results when on a clean dry surface with ample grip. Push steering, depending on the strength of your push and the lean required, makes demands of grip. You can push steer on a wet surface it'southward merely that the push or forrad pressure needs to exist administered more steadily rather than harshly. Once again, grip is required then doing this on a loose surface such as gravel requires inputs adjustments or an alternative manoeuvre choice.
COULDN'T I Merely Plough THE HANDLEBARS? A bike can negotiate a curve only when the combined center of mass of bike and passenger leans towards the inside of the plough. This, at an angle appropriate for the velocity and the radius of the plough. College speeds and tighter turns require greater lean angles. If the mass is non first leaned into the turn, the inertia of the rider and wheel will cause them to go along in a straight line as the tires track out from under them along the curve. The transition of riding in a straight line to negotiating a turn is a process of leaning the wheel into the turn, and the but fashion to cause that lean (of the combined centre of mass of bike and passenger) is to motility the back up points in the reverse direction first. You can shift your weight of course, simply whatsoever force used to motility one way laterally pushes the bike laterally the opposite management with equal force. That makes the bicycle lean (and tin touch the steering), but it does not modify the combined centre of mass of wheel and rider.
IS THERE More I Need TO DO WHEN EXITING A CORNER OR Plow? Once in a turn, push steering is again required to make changes to its shape. The only fashion to decrease the radius at the same speed is to increment the lean angle, and the only way to increase the lean angle, is once again to momentarily steer opposite to the direction of the bend. To an untrained passenger, this tin be extremely counter-intuitive. To exit a turn, push steer by momentarily steering farther in the direction of the turn. This tilts the cycle back upright.
DOES Button STEERING Piece of work WHEN I'M RIDING AT Low SPEEDS? At low speeds fifty-fifty then, yes, your single rail vehicle has gained gyroscopic inertia. But button steering is then subtle that it is hidden by the ongoing corrections made in balancing the bike. Push steering at low speed may be farther concealed by the ensuing much larger steering bending possible in the management of the turn. It really works all-time on a motorbike when inertia is increased using about 10km per hour.
DOES THIS WORK IN MY FOUR WHEELED VEHICLE? No, it's a method used for a single track vehicle. However, the term is referred to when explaining the four-bicycle auto driving technique of drifting.
WOULD I Apply Push STEERING ON MY PIAGGIO MPS OR MY YAMAHA NIKEN? Yes as these types of models take two front parallel wheels. The wheels are linked mechanically and are push steered in the same manner as a ii-wheeled motorcycle.
Tin I Push button STEER THE Three-WHEELED CAN-AM SPYDER OR MY TRIKE? No, these type of 3-wheelers utilise steering. There is no leaning required beingness that you are on three wheels, so yous turn it as an car or 4 tracked vehicle.
IS THIS THE SAME AS "POSITIVE STEERING"? Yep, "postive steering" refers to the push steering. It is often used as a psychological term to foreclose the rider from becoming fearful in learning to practice push button steering.
To be very clear about this skill, if you are reading this and accept not felt the furnishings of push steering on your motorcycle – you have not learned the technique – nor the fine art and arts and crafts of button steering.
EXERCISES FOR Push button STEERING ENLIGHTENMENT
When learning and discovering push steering, y'all really just have to feel one successful push button steer to exist enlightened. It is best discovered under supervision of an expert motorbike teacher. However, if you don't have the ability to discover a coach, try the post-obit. Note: put your safety get-go and foremost.
PART ONE: Go to a spacious parking lot or a individual route where you accept ample uninterrupted space and where the surface is concrete or paved; is dry, polish and gratuitous of route debris. A space which has enough room to ride in a straight line at higher mid-range public route speed.
PART TWO: Accelerate in a direct line taking your motorcycle upwardly to a depression average traffic speed this could be 2nd gear mid to loftier range (depending on your motorcycle type, this may vary). If y'all are travelling at besides depression of a speed, such as walking step, push steering volition not be every bit effective, noticeable or will not occur at all. Inertia is required.
You lot just accept feel one successful push steer to be aware.
Part Iii: With hands on handlebar grips, and at constant speed, push forward on either your left OR right bar. Not both. Determine which one you will push forwards on before yous advance from a stop – and focus on that direction. Be mindful during your "push" taht you lot do non roll off your throttle, or utilize braking – continue constant speed. You will find as a result, when you employ forwards pressure to the handlebar, your motorcycle will motility to the management you lot pushed! Voila – push button steering.
PUSH STEERING WRAP UP
Push steering is absolutely necessary for motorcycle steering. Mastering the skill of consciously push-steering is crucial for safe motorcycle riding. The art of motorcycle cornering is learning how to effectively "push" on the handlebar grips into corners and how to keep up proper lean angles through the plough. When the demand for a quick swerve ( to avoid collision or an object) all of a sudden arises, information technology's essential to know the handlebars must be purposely pushed away on that side instead of being pulled or steered.
Eventually when practises, and rehearsed, this manoeuvre volition become embedded into musculus memory and you will naturally, without thinking, use push steering.
Push steering adds a confident, masterful and super fun rider component to your motorcycle riding!
