Whether you are threading a fast chicane or braking deep into a hairpin, this unit keeps the rear wheel planted and the bike obediently on line — lap after lap, without fatigue.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eEliminates engine over-rev on aggressive downshifts, delivering a smooth, controlled deceleration that keeps your entry line intact\u003c\/li\u003e\n\u003cli\u003eReduces rear-wheel hop to improve traction and stability under trail braking — less drama, more confidence in the saddle\u003c\/li\u003e\n\u003cli\u003eLowers the trigger impulse of a potential highside, significantly reducing risk at high speed and giving the rider a genuine safety margin\u003c\/li\u003e\n\u003cli\u003eAllows controlled rear-wheel slides for a more progressive, predictable handling balance during spirited riding\u003c\/li\u003e\n\u003cli\u003eImproved clutch-closure control through corners prevents the front end from tucking — a critical benefit when carrying speed mid-turn\u003c\/li\u003e\n\u003cli\u003eDiaphragm spring design smooths lever release and eliminates pressure-plate judder, reducing hand fatigue on long track sessions or spirited road rides\u003c\/li\u003e\n\u003cli\u003ePatented ball-ramp mechanism governs the slipper function with precision at high revs, providing consistent, repeatable performance every time\u003c\/li\u003e\n\u003cli\u003eSaves approximately 0.7–0.8 kg in rotating mass, reducing drivetrain inertia and sharpening throttle response across the entire rev range\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eAll-Day Comfort and Ride Quality\u003c\/h2\u003e\u003cp\u003eOne of the most overlooked benefits of a high-quality slipper clutch is how much more comfortable the riding experience becomes over the course of a full day. The diaphragm spring inside the STM unit requires less lever effort than a standard spring-plate clutch, so your left hand is not fighting the lever at every corner entry. Over a long track day or an extended road run, that reduction in effort adds up to noticeably less arm and hand fatigue — leaving you fresher, sharper and able to ride at your best when it matters most.\u003c\/p\u003e\u003cp\u003eThe improved clutch-closure feel also gives you a cleaner mental picture of what the rear tyre is doing, removing the guesswork that a chattering or hopping wheel creates. That clarity translates directly into greater confidence on corner entry, which is where lap times and riding enjoyment are truly made.\u003c\/p\u003e\u003ch2\u003ePatented Ball-Ramp Technology\u003c\/h2\u003e\u003cp\u003eSTM's patented ball-ramp system is the engineering heart of this clutch. Rather than relying on crude friction-based slippage, the ball ramps meter the degree of clutch disengagement in direct proportion to the level of engine braking force being generated. The result is a progressive, linear response that adapts to each downshift situation — aggressive or gentle — without any sudden release or unexpected rear-end behaviour. At race pace, where margin for error is zero, that precision is the difference between a controlled slide and an uncontrolled moment.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThis STM slipper clutch is a direct-fit replacement for the following models:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eKawasaki ZX-6R — 2007 to 2018\u003c\/li\u003e\n\u003cli\u003eKawasaki ZX-6R 636 — 2007 to 2018\u003c\/li\u003e\n\u003cli\u003eKawasaki ZX-6RR — 2007 to 2018\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eBrand\u003c\/th\u003e\n\u003ctd\u003eSTM\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePart Number\u003c\/th\u003e\n\u003ctd\u003eFKW-S050\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eType\u003c\/th\u003e\n\u003ctd\u003eSlipper \/ anti-hopping clutch\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFitment\u003c\/th\u003e\n\u003ctd\u003eKawasaki ZX-6R \/ 636 \/ RR (2007–2018)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWeight Saving\u003c\/th\u003e\n\u003ctd\u003eapprox. 0.7–0.8 kg (rotating mass reduction)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMechanism\u003c\/th\u003e\n\u003ctd\u003ePatented ball-ramp anti-hopping system\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSpring Type\u003c\/th\u003e\n\u003ctd\u003eDiaphragm spring\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"STM","offers":[{"title":"Default Title","offer_id":53168706126090,"sku":"FKW-S050","price":1494000.0,"currency_code":"RWF","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/FDU-S050_cb2bc090-5c5e-4d99-ac6b-abe9a2b4bc28.png?v=1780811745","url":"https:\/\/inter-pace.com\/en-rw\/products\/stm-slipper-clutch-kawasaki-zx-6r-636-rr-fkw-s050","provider":"Inter-Pace","version":"1.0","type":"link"}
