Sigma Slipper Clutch GSXR1000 K1-K4 - GSXR1000 2001-2004

Sigma Performance Slipper Clutch (5 Ramp, wet type) Uses standard clutch plates and Springs (not included). 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 whenever 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 individually designed using carefully chosen ramp angles with ball bearings for the smoothest performance possible. Full instructions supplied. (Ref 015)
