Race proven slipper clutch for the 2009 - 2014 Yamaha R1
Upgrade you stock slipper clutch with one that slips earlier and smoother than the stock clutch. We use ball bearings on the ramps for superior performance to the OEM ramp on ramp design.
Since the clutch weighs less than stock, the motorcycle's performance is improved.
This clutch is complete with new springs, tuning parts, and a new pull lever for better modulation. Testing with pro level riders has shown that this clutch is good for at least 1/2 a second on a typical track.
