A motorcycle slipper clutch operates by reducing the pressure on the clutch pack when the rear wheel it trying to turn the engine. Road racing type slipper clutches have no effect on the clutch engagement when the engine is trying to drive the rear wheel.
When the motorcycle is slowing for a turn (Engine Braking) the torque forces the ramps together; The ramps then ride up to each other, and this action lifts the splined part of the hub off of the base. Better Design, Higher Quality Parts. JUST PLAIN WORK,BETTER, and more consistenly. You won't think your bike had a Slipper Clutch in it from the Factory once you upgrade to this one.  OEM Swap Out.  Takes no time to swap out.
