Motorcycle Permit Practice Test

The front brake is considered the most important on a motorcycle because it provides 70-80% of the motorcycle's stopping power. Although using both brakes is ideal, the front brake is crucial for quickly and safely stopping the motorcycle. Using the back brake alone may cause the motorcycle to skid or lose control, and the left brake option is not a commonly used or recognized brake on a motorcycle. Therefore, the front brake is the most important one to use when riding a motorcycle.
