What is the effect of using only the front brake when stopping?

Using only the front brake when stopping a motorcycle can lead to serious consequences, including the potential for the motorcycle to flip over. This happens because most of the motorcycle's weight shifts forward when braking, particularly when only the front brake is engaged. The front brake has a significantly stronger stopping power than the rear brake, which means that relying solely on it can cause the front wheel to lose traction. If the weight shifts forward too much and the front wheel locks up, it can result in the rear wheel lifting off the ground, leading to a loss of control and an increased risk of a crash. Therefore, it is essential to use both brakes in a balanced manner when stopping to maintain stability and ensure a safe stop.
