Why does the rear wheel of a motorcycle tend to lock when braking rather than the front wheel?

When braking on a motorcycle, the dynamics of weight distribution play a crucial role. The situation can lead to two main factors that influence the behavior of the wheels during braking.

Firstly, when you apply the brakes, weight shifts forward due to inertia. This shift reduces the load on the rear wheel, making it more susceptible to locking up.

Secondly, when the motorcycle is in motion, the rear wheel is still being powered by the engine, which can contribute to it locking up under hard braking conditions.

In summary, both the reduction of load on the rear wheel and the fact that it is still driven by the engine are critical factors. Understanding these dynamics is important for safe motorcycle operation and is reflected in safety regulations and best practices outlined by German traffic laws. Proper braking technique requires the use of both brakes, as this helps distribute weight more evenly and reduces the chance of either wheel locking up, which is essential for maintaining control and stability while riding.
