Emergency braking on a motorcycle

Someone will say, they say, when driving in the city, any braking can be called emergency, because you will not slow down for no apparent reason, city traffic is quite dense. So, emergency braking is distinguished from any other by the amount of time it takes to slow down to the required speed, and its you for this it is obscenely little.

The fear of not having time to slow down leads to panic, and that inevitably drags fatal mistakes along with it. Let’s consider the main points.

Position of motorcycle and steering wheel

In case of emergency braking, remember the main axiom, which is undeniable: if you make a maneuver, then the brakes must be released, and if you brake, then you do not steer.

Let me explain. With the brake lever clamped, the wheel is already puzzled by the blockage during movement, and when you are still about to turn it, the motorcycle either stalls or wobbles. Any maneuvers with the brakes applied will only increase the risk of falling and, at the same time, reduce the effectiveness of the braking itself.

When talking about the position of the motorcycle, it is very important that it is in a level, upright position. So that the brakes work with a bang and the manufacturer would not be ashamed in front of your family for the fact that your braking distance turned out to be longer, do not interfere with them doing their job. With any tilt of the motorcycle or maneuver with the body, the steering wheel, you somehow change the contact patch of the tire with the road surface. Now imagine, you put on the gorgeous brakes on your supersport, put it under your knee in the city (which, in principle, is not a fountain), when a car takes off at the intersection, and you are already in the turn. Since you are in a maneuver, the contact patch on the tire moves towards the edge, naturally less grip. You put on the brakes, yes, the wheel is locked, but the speed and angle of the wheel do not give the wheel full grip. In the first case, you simply will not have time to stop, in the second case, braking in a turn will lead to a wheel breakdown and fall.

Wheel break

There is no need to argue for a long time about wheel breakdown. In general, wheel stall is a side effect of cornering braking. In fact, it is possible to call this phenomenon “drift”, it is just that drift is not always caused by the action of the brake. The stall in emergency braking happens so abruptly that you feel like your wheel has actually been blown off. When you first enter a turn, the front wheel often breaks off, since its angle of inclination does not correspond to the vector of movement of the entire motorcycle. But when exiting the turn, the rear wheel suffers, since most of the motorcycle has almost left the maneuver, and the rear wheel did not have time to rearrange itself.

Emergency braking is very dangerous when cornering because you have to either maneuver or brake. And when you break this rule and apply the brake, but try to steer, the wheel locks up or the steering axle turns sharply to the side, the tire grip is reduced to zero and you just fly head over heels along the track.

Brake operation

During emergency braking, working with only one brake is not reasonable, you need to combine it. The fact is that if you brake sharply only with the front brake, then overload the fork and if you do not fly over the steering wheel in the first three seconds, then you will definitely go to the stop. If you emergency brake only with the rear brake, then blocking it will either lead to wheel skid, or to less braking efficiency in general.

The conclusion is to use both brakes.

Let’s summarize

Actions during emergency braking:

  • Align motorcycle and wheelbase
  • Do not maneuver while braking
  • Use both brakes
  • Do not panic
