Sigma Performance Slipper Clutch (6 Ramp, wet type)

Sigma slipper clutches are designed to allow easier downshifting on the road or track.  Originally a pure race accessory, Sigma slipper clutches smooth gear changes for skilled riders and beginners alike by automatically and seamlessly disengaging the clutch whevever engine braking or rear wheel hop becomes and issue.

Sigma slipper clutches give smoother performance on corner entry and exit, crisper shifting action and increased drive from the engine over OEM slipper units. 

All clutches are supplied with alternative spring preload spacers to allow slip levels to be adjusted.  Each clutch is invidually designed using carefully chosen ramp angles with ball bearings for the smoothest performance possible. 

Uses standard clutch plates (not supplied) and springs (supplied).  Full instructions supplied.
