The Yamaha R1 has great potential on the race track .. and its standard slipper clutch improves its performance no end.  Improving corner entry stability and helping to limit excess over-revving on corner entry.

Our unit takes the slipper clutch concept one stage further with shallower ramp angles with ball bearings in the mechanism to allow the clutch slip more readily and smoothly going into corners. By reducing the amount of grip ‘used up’ turning over the engine our clutches have the potential to reduce lap times and improve competitiveness.

  • Six ramp, wet type.

  • Clutch centre only.
