How much of a motorcycle's total stopping power does the front brake supply?

The front brake typically supplies about one-half of a motorcycle's total stopping power. This is due to the physics of braking and weight distribution when a motorcycle comes to a stop. When a rider applies the brakes, the weight of the motorcycle shifts forward, increasing the traction on the front tire. This additional grip allows the front brake to be more effective than the rear brake in decelerating the motorcycle.

Front brakes usually have larger diameter rotors and more advanced braking systems, such as anti-lock brakes, compared to rear brakes, which allows for more stopping power. Understanding this distribution of stopping power is essential for effective braking strategies, ensuring that riders can stop safely and efficiently while maintaining control of their motorcycle.

The other options, while they suggest varying amounts of stopping power from the front brake, do not reflect the typical performance and dynamics observed in motorcycle braking. Recognizing the importance of the front brake and its role can significantly enhance a rider's safety and handling skills on the road.
