What is the best way to stop quickly on a motorcycle?

Using both brakes simultaneously is the safest and most effective way to stop quickly on a motorcycle. This method allows for optimal braking performance because both the front and rear brakes contribute to slowing down the motorcycle. The front brake provides the majority of stopping power, typically around 70-90%, due to the weight transfer that occurs when braking. Engaging both brakes ensures better control and stability during the stop, helping to prevent skidding or losing traction.

Gradually reducing speed, while useful in certain situations like approaching a red light, does not effectively address the need for a quick stop in an emergency scenario. Relying solely on the rear brake could compromise stopping power and stability, as the front brake is essential for effective braking. Shifting to a lower gear can assist with engine braking but is not a primary method for stopping quickly. Hence, for immediate stopping, using both brakes is the recommended technique.
