What could result in grabbing the front brake too hard?

Answer: B — front wheel lock

Grabbing the front brake too hard can lead to a front wheel lock, which occurs when the brakes are applied with excessive force. This situation can cause the front tire to lose traction on the road surface, leading to a dangerous loss of control of the motorcycle. When the front wheel locks up, the motorcycle can either tip forward or slide, increasing the chances of an accident. This is particularly hazardous, as the front brake is responsible for a significant portion of the motorcycle's stopping power. Proper braking techniques, which include progressively applying the brakes rather than grabbing them suddenly, are essential for maintaining stability and control.
