What is a slipper clutch?

A slipper clutch, also known as a back-torque limiter or anti-hop clutch, is a device used in motorcycles and some high-performance cars to prevent wheel hop or skidding during aggressive downshifting.

When a rider downshifts gears at high speeds, the rear wheel can lock up due to the compression braking effect of the engine. This can cause the rear wheel to slide or hop, leading to loss of control. A slipper clutch helps to mitigate this effect by allowing the clutch to slip slightly when the engine revs are higher than the wheel speed, reducing the braking force on the rear wheel.

Slipper clutches typically consist of a set of specialized friction plates and springs that engage and disengage the clutch under certain conditions. They can help improve stability and control during aggressive riding or racing, as well as reduce wear and tear on the transmission components.

Overall, slipper clutches are a valuable addition to high-performance vehicles, providing a smoother and safer riding experience for the rider.
