STM Slipper Clutch

STM slipper clutches will help eliminate rear-wheel chatter and
reduce chassis instability during aggressive downshifting.
Slipper clutches reduce the engine-braking effect the makes the
rear wheel hop around under heavy downshifting.
  • STM offers the only adjustable slipper clutch on the market
  • The STM slipper clutch brings innovative performance
    improvements to the street market through the controlled engine
    braking system (CEB)
  • Highly effective engine to clutch-to-rear wheel power
    management system decreases unwanted engine braking and
    rear wheel drag when braking hard for a corner
  • Prevents damage to the engine and gearbox by reducing the
    mechanical stress caused by the back-torque of the engine and
    avoiding any chance of over-revving
  • Provides better clutch feel and smoother action
  • Uses original friction plates, drive plates, and basket
