New York City Motorcycle Permit Practice Test

What percentage of potential stopping power does the front brake supply?

1. About 50%

2. About 60%

3. About 70%

4. About 80%

The correct answer is: About 70%

The front brake of a motorcycle is responsible for a significant portion of its stopping power, typically around 70%. This is due to the weight transfer that occurs when a rider applies the brakes: as the motorcycle slows down, the weight shifts forward, increasing the traction on the front wheel. This enhanced traction allows the front brake to effectively contribute to a majority of the motorcycle's overall deceleration. Using the front brake efficiently is crucial for safe riding, as it not only stops the motorcycle quickly but also maintains stability during the braking process. Riders are trained to apply both brakes together for optimal stopping performance, but understanding that the front brake provides the most force can help in developing effective braking techniques. The figures for the other choices reflect common misconceptions about braking percentages but do not account for the dynamic forces at play when braking. By recognizing the substantial role the front brake plays, riders can be more effective and safer in emergency stopping situations.
