Fitment Notes & Exceptions

DD6 (Direct Drive) vs OD6 (Overdrive)

  • DD6 is meant for touring bikes up to 120ft/lbs and offers smoother shifting due to a shallower 1 degree undercut on the clutch dog teeth
  • OD6 is meant for performance and race applications up to 165ft/lbs due in part to a more aggressive 4 degree undercut on the clutch dog teeth
  • Both Gear Sets reduce engine speed by 500 RPM at 80MPH
  • DD6 achieves an overdrive effect on the highway by overdriving the primary with a 28 tooth motor sprocket 
  • OD6 has an overdrive (.86:1) 6th gear that can be used with any sprocket for increased gearing options
