STM Italy: Anti-rebound clutches and racing components for motorbikes

STM Italy is synonymous with Italian engineering applied to high level motorcycling. Specialists in the design and manufacture of anti-rebound clutches, STM develops innovative solutions for racing, sports and custom bikes. At BeRacing1 we offer a wide range of products STM, designed to improve performance, control and reliability on the track and on the road.

What is a slipper clutch? STM

An anti-rebound clutch STM partially disengages the transmission during hard downshifts, preventing rear wheel lock-up, bounce or loss of traction. This technology, derived directly from racing, offers:

• Increased stability under hard braking
• Smoother gear transitions
• Reduced stress on the engine and gearbox
• Increased confidence when driving on racetracks or sporty roads
