Clutch kit harnesses the centrifugal force of spinning weights to increase the clutch capacity as engine speed increases.

  • Mechanism applies increasing pressure to the stock clutch pressure plate as RPM rises
  • High torque-handling capabilities without increasing clutch lever effort at idle
  • Variable pressure clutch also provides smoother clutch disengagement at lower speed
  • Kit fits behind most stock derby covers with no modifications
  • See installation manual for additional accessory derby cover fitment information
