What could happen if you grab the front brake too aggressively?

When you grab the front brake too aggressively, the weight of the motorcycle shifts forward onto the front wheel. If the braking force exceeds the friction available between the front tire and the road, it can cause the wheel to lock. A locked front wheel can lead to a loss of steering control, which can be very dangerous as it may result in a skid or crash.

In contrast, the other outcomes mentioned do not accurately reflect the immediate effect of applying the front brake too hard. For example, while the rear tire may lift if the front brake is applied excessively, that situation depends on multiple factors, including the speed and weight distribution of the motorcycle. Simultaneously, the bike will not speed up; instead, it is meant to decelerate when brakes are applied. Furthermore, while a malfunctioning brake light is a concern, it is unrelated to the physical dynamics of braking improperly. Thus, the correct answer highlights a crucial aspect of motorcycle handling and safety.
