DescriptionThe whole story▼
For riders who demand total control over every gear change and corner entry, the STM EVO SBK dry clutch conversion for the Ducati Panigale V2 955 is an engineered step-change. Replacing the standard wet clutch with a purpose-built SBK-specification dry unit, it delivers measurably reduced power loss, a significant saving in rotating mass, and a level of clutch feel that makes long track sessions and spirited road riding considerably less fatiguing on the hand and the mind.
Key Features
- Reduced power loss through dry clutch operation for sharper, more responsive acceleration out of every corner
- Prevents engine over-rev on downshifts, maintaining a stable, composed drive line under hard braking
- Suppresses rear-wheel hop for improved traction and stability in demanding conditions
- Lowers the trigger impulse of a highside event, adding a meaningful safety margin at speed
- Enables controlled rear-wheel slides, giving experienced riders the handling nuance to exploit track conditions
- Patented ball-ramp mechanism governs the slipper/anti-hopping function with precision at high rpm
- Diaphragm spring design eliminates pressure-plate judder, delivering a smoother, more progressive clutch release that reduces hand fatigue over long stints
- Weight saving of approximately 0.7–0.8 kg through reduction of rotating mass, directly benefiting acceleration and engine response
Engineering & Build Quality
STM's EVO SBK unit is built to the same standard as the components the Italian brand supplies to World Superbike teams. The patented ball-ramp slipper system is the core of its advantage: ramps engage progressively under engine braking to modulate back-torque precisely, preventing the abrupt rear-wheel locking that can unsettle a bike mid-corner. The diaphragm spring replaces the conventional coil-spring stack, removing the tilting motion of the pressure plate that causes the grabby, inconsistent feel many riders notice with standard clutches. The result is a lever action that feels natural and consistent whether you are threading through traffic or threading through a chicane.
Performance on Road and Track
The shift from wet to dry operation eliminates the viscous drag that a wet clutch generates even when fully disengaged. On the Ducati Panigale V2 955 this translates to a cleaner power delivery from the moment the lever releases, and a more direct connection between throttle input and rear-wheel response. The weight reduction of roughly 0.7–0.8 kg comes almost entirely from rotating components, meaning the engine revs more freely and responds faster to throttle changes — a benefit that is felt immediately and compounds with every gear change throughout a lap. For riders who use a slipper clutch to manage corner entry, the controllable rear-wheel slide characteristic of the dry unit adds a dimension of adjustability that the stock setup simply cannot offer.
