STM SM 500R Slipper Clutch

This slipper clutch is designed to eliminate rear-wheel chatter/lock-up and the resulting chassis instability that occurs upon aggressive downshifting, STM’s patented ball and ramp slipper clutches reduce engine braking to make tap-dancing gear changers into smooth operators - smoothness being the key to safe and fun riding, both on track and road. In addition the STM slipper clutches offer increased clutch life, reduced clutch-lever effort and greater sensitivity in low-traction conditions.
