High-performance clutches and sprockets
for small racing engines
SMC clutches are typically used on karts, snowmobiles, and mopeds.
Go faster.
SMC discs, levers and springs are carefully engineered to cause lockup in the shortest possible distance. This mechanical efficiency results in less heat, leaving more power for acceleration.
Spend less.
SMC Vortex and Aggressor clutches can be easily and expertly rebuilt at the racetrack by the racer with common hand tools. All parts are factory blueprinted. Stop wasting time and money on clutch "gurus".
