It replaces the standard wet clutch with a proven dry-clutch system that reduces power loss, sharpens engine response and gives you a noticeably better feel every time you roll onto the throttle or brake into a corner — on the road or on circuit.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReduced power loss compared to the OEM wet clutch, putting more of the engine's output to the rear wheel on every ride.\u003c\/li\u003e\n\u003cli\u003ePrevents engine over-rev on downshifts, keeping the drivetrain stable during aggressive trail-braking and fast gear changes.\u003c\/li\u003e\n\u003cli\u003eMinimises rear-wheel hop under hard deceleration and allows controlled sliding — a clear advantage both on track and in spirited road use.\u003c\/li\u003e\n\u003cli\u003eWeight saving of approximately 0.7–0.8 kg through a reduction in rotating mass, improving throttle response and reducing inertia.\u003c\/li\u003e\n\u003cli\u003ePatented ball-ramp mechanism governs the anti-hopping function for precise, progressive clutch control at high engine speeds.\u003c\/li\u003e\n\u003cli\u003eImproved corner-entry behaviour during clutch engagement: the system actively resists front-end dive, giving a more planted, confident feel.\u003c\/li\u003e\n\u003cli\u003eDiaphragm spring design prevents pressure-plate flutter, delivering a smooth, consistent lever release with no chatter at the handlebar.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eEngineering Detail\u003c\/h2\u003e\u003cp\u003eThe EVO SBK is STM's road-and-track dry clutch, developed directly from their Superbike racing programme. At the heart of the system are STM's patented ball ramps, which self-regulate back-torque limiting without requiring manual adjustment. The diaphragm spring replaces the conventional coil-spring stack, eliminating the mechanical instability that causes pressure-plate judder — something riders notice immediately as a cleaner, more linear lever feel from engagement to full release.\u003c\/p\u003e\u003cp\u003eThe reduction in rotating mass is achieved by moving away from the oil-bath architecture of the original wet clutch. Less spinning mass means the engine revs more freely, responds faster to throttle inputs and is easier to control at the limit. For riders who regularly use their RSV4 on both public roads and track days, this translates into a more usable, communicative clutch in every riding scenario, not just at maximum attack.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eThe STM EVO SBK dry clutch KTT-3600 is a direct-replacement conversion kit designed specifically for the following models:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eAprilia RSV4 (2015–2026)\u003c\/li\u003e\n\u003cli\u003eAprilia RSV4 RF (2015–2026)\u003c\/li\u003e\n\u003cli\u003eAprilia RSV4 RR (2015–2026)\u003c\/li\u003e\n\u003cli\u003eAprilia RSV4 1100 Factory (2015–2026)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eThis kit replaces the complete OEM wet-clutch assembly.
