The "Evoluzione SBK" slipper clutch is the spearhead of the Ducati anti-skid systems used by pilots and racing teams competing in the world and national championships.

THE HEART OF THE STM SLIPPER DRY CLUTCH 

PRIMARY SPRING

• pressure action on the DISC PACK through the pressure plate;
• function of coil springs.

SECONDARY SPRING

• pressure action on the DRUM;
• serves to adjust the clutch opening during the anti-skid, then to adjust the engine brake.

HOW THE SPRINGS WORK

The primary and secondary springs are mounted in such a way as to guarantee a preload which generates an initial resilient spring force.

HOW THE PRIMARY SPRING WORKS

When the lever is actuated, the preloading position of the primary spring is varied and reduced. The spring returns an elastic force of contrast to the action of the lever.

HOW THE SECONDARY SPRING WORKS

The torque generated by the rear wheel tends to raise the drum. The secondary spring is compressed with respect to the initial resting position and generates an elastic contrast force.

WHY INSTALL A STM CLUTCH?

• Prevent engine overspeed;
• Avoid hopping the rear wheel;
• Make it possible to climb without using the clutch;
• Allow controlled sliding of the rear wheel;
• Manage the closing phase of the clutch when cornering (to avoid unbalance);
• Allow a better management in the release of the lever (start) thanks to the diaphragm spring.
