Which brake provides the majority of stopping power on a motorcycle?

The front brake is the primary source of stopping power on a motorcycle for several critical reasons. When applying both brakes, a significant portion of the motorcycle's weight shifts forward due to the deceleration. This shift increases the traction on the front tire, allowing the front brake to effectively engage more forcefully.

During braking, the front brake can utilize more of the motorcycle's weight and balance, while the rear brake mainly assists in stability control. It's crucial for riders to understand that improper use of the brakes can lead to accidents; over-reliance on the rear brake can cause skidding or loss of control. Thus, mastering the front brake not only enhances stopping efficiency but also contributes to overall riding safety.

Other choices represent elements of braking but do not significantly contribute to the stopping power in the way that the front brake does. For instance, the rear brake provides additional support but plays a lesser role in overall stopping performance. The emergency brake is not typically used on motorcycles like it is on cars, and the anti-lock brake system is designed to prevent wheel lock-up during hard braking rather than serving as a primary braking mechanism. Thus, the front brake is essential for effective stopping.
