"High side" typically refers to a specific type of motorcycle crash that occurs during cornering when the rear tire loses traction, regains traction suddenly, and launches the rider off the motorcycle towards the outside of the turn. It's an undesirable situation that can cause serious injuries.
If you meant to ask how to stop a motorcycle safely or how to prevent a high side crash, here are some general guidelines:
Brake smoothly: Gradually apply both the front and rear brakes, using progressive and controlled pressure. Avoid grabbing the brakes suddenly, as it can cause the wheels to lock and potentially lead to a loss of control.
Downshift: As you slow down, downshift through the gears to match the appropriate gear for your speed. This helps to keep the engine in the appropriate RPM range and allows for a smoother transition to a complete stop.
Use engine braking: Utilize the natural deceleration of the engine by downshifting and releasing the clutch gradually while maintaining a light throttle. Engine braking helps to slow down the motorcycle while reducing reliance on the brakes, especially the front brake, which can cause the rear wheel to lift and potentially result in a loss of control.
Look ahead and plan your stop: Pay attention to the road and anticipate when you need to stop. Being aware of your surroundings and maintaining a safe following distance from other vehicles will give you more time to react and apply the brakes smoothly.
Use both brakes: In most situations, it's recommended to use both the front and rear brakes together for effective braking. The front brake provides the majority of the stopping power, so apply it progressively and avoid excessive force. The rear brake helps stabilize the motorcycle and provides some additional braking power.
Remember, it's important to practice safe riding techniques and be familiar with your motorcycle's braking system. Each motorcycle may have slight variations in braking performance, so consult your motorcycle's owner's manual for specific guidance on braking techniques and maintenance.
