What fraction of stopping power does the front brake provide?

The front brake is responsible for providing a significant amount of the motorcycle's stopping power, typically around three-fourths. This is due to the dynamics of weight transfer that occurs when a motorcycle decelerates. When braking, the weight of the bike shifts forward, increasing the load on the front tire and enhancing its grip on the road. As a result, the front brake is more effective in slowing down the motorcycle compared to the rear brake, which generally only provides about one-fourth of the total braking power.

Understanding this balance is crucial for safe riding; effective use of both brakes can maximize stopping efficiency and control. While the rear brake can assist in slowing down, relying predominantly on it may lead to skidding or loss of control, particularly in situations of sudden braking. Therefore, recognizing the importance of the front brake in stopping power can greatly improve a rider's ability to respond to emergencies or abrupt stops on the road.
