Which brake provides more stopping power on a motorcycle?

Answer: B — Front brake, 70%

The front brake provides more stopping power on a motorcycle because it handles approximately 70% of the braking force. This is due to the dynamics of weight transfer during braking. When a motorcycle decelerates, the rider's weight shifts forward onto the front wheel. This increased weight on the front tire allows it to generate more traction and grip on the road surface, making the front brake significantly more effective. Utilizing both brakes during a stop is important for optimal braking performance; however, relying primarily on the rear brake may not provide the most efficient deceleration. The rear brake has its importance, particularly in controlling slides and maintaining stability during certain riding conditions, but for maximum stopping power, the front brake is crucial.
