About this collection
Clutches
Slipper and race clutches from STM and Spider Racing — the components that let you attack corner entry without the rear wheel hopping in protest.
A slipper clutch limits back-torque on aggressive downshifts, keeping the chassis settled where a stock clutch would chatter. STM's Evoluzione units are the benchmark, with tunable spring rates and serviceable plate packs. Engine-specific fitment throughout; plate kits and springs are available separately for units already in service.
