Which brake provides about three-quarters of a motorcycle's total stopping power?

The front brake is crucial in providing about three-quarters of a motorcycle's total stopping power due to the dynamics of motorcycle physics. When a motorcycle slows down or comes to a stop, weight shifts forward, increasing the load on the front wheel while reducing it on the rear. This weight transfer allows the front brake to generate significantly more stopping force than the rear brake can.

The design and placement of brakes on motorcycles also contribute to this phenomenon. The front brake typically has larger rotors and a more powerful caliper setup compared to the rear, enabling more effective braking. Additionally, riding techniques often emphasize the use of the front brake for sudden stops or emergency braking, reinforcing its importance in overall stopping efficiency. Knowing how to properly use both brakes together, while primarily relying on the front brake for maximum stopping power, is critical for safe motorcycle operation.
