            Sigma Performance Slipper Clutches From UK Race Support Limited

Now with 60 different clutches, our range incorporates many popular street bikes as well as the race applications that have made our name. Sigma slipper clutches are designed to allow easier downshifting on the road or track. Originally a pure race accessory our 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 an issue. 

During 2011 Team WFR used our clutches to dominate the BSB Evo championship on their Honda CBR1000RR’s while we also had success in Evo with Buildbase BMW using one of our clutches in their S1000RR to win the Thruxton EVO race. In BSS Supersport we won races and got podiums with Kawasaki 600’s, Yamaha R6’s and Triumph 675’s. Riders report smoother performance on corner entry and exit, crisper shifting action and increased ‘zip’ from the motor as major improvements over the 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 on road or track. All are supplied with full instructions.  Most models use standard springs and plates.
