What percentage of a motorcycle's stopping power is provided by the front brake?

Answer: B — 70%

The correct answer is that about 70% of a motorcycle's stopping power is provided by the front brake. This is crucial information for motorcyclists because the weight of the bike shifts forward during braking, which enhances the effectiveness of the front brake. Understanding this balance is vital for safe riding, as relying solely on the rear brake can lead to longer stopping distances and decreased control. This statistic highlights the importance of practicing proper braking techniques and using both brakes effectively to ensure safety while riding.
