STM Slipper Clutch - KTM 450

Since 1994 the company STM is specialized in the production of high precision mechanical parts for motorcycles. With a fleet of ultra-modern machining centers, it makes such a clutch system called ingenious CEB (Engine Braking Control).

• Eliminates negative effects of engine brake, allowing better grip
• Reduces dribbling effect
• Balls placed between pressure plate and inner hub limit engine brake when it becomes too important
• Enables to downshift from 6th to 1st without blocking the rear wheel
• Developed for Superbike and Supermoto
• R&D made with racing teams
• This slipper clutch system replaces the OE inner hub and pressure plate. This system keeps the OE clutch basket and OE steel plates and friction plates
