Motorcycle Permit Practice Test

The rear brake provides ___________ of the motorcycle's stopping power.

1. Half

2. One Quarter

3. One Third

4. Three Quarters

The correct answer is: One Quarter

The rear brake plays an important role in stopping the motorcycle, but it does not provide the majority of the stopping power. In fact, the front brake is responsible for approximately 70-80% of the motorcycle's stopping power. This is because when the front brake is applied, the weight of the motorcycle shifts forward, putting more weight on the front wheel and increasing traction. Rear braking alone can cause the motorcycle to skid or lose control, which is why it should always be used in conjunction with the front brake. Therefore, options A, C, and D are incorrect because they overestimate the rear brake's stopping power and do not take into account the role of the front brake. Option B, one quarter, is the most accurate as it reflects the smaller but still significant role of the rear brake in stopping the motorcycle.
