Engineered for track and sport riding, part number FBM-S020 eliminates rear-wheel hop and reduces the risk of a highside with a precision that no standard OEM clutch can match.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003ePrevents engine over-rev on aggressive downshifts, maintaining stable power delivery across all riding modes\u003c\/li\u003e\n\u003cli\u003eEliminates rear-wheel chatter for precise traction and control under both acceleration and hard braking\u003c\/li\u003e\n\u003cli\u003eReduces the trigger impulse of a highside, adding a critical safety margin at track speeds\u003c\/li\u003e\n\u003cli\u003eEnables controlled rear-wheel slides for confident, sport-oriented riding\u003c\/li\u003e\n\u003cli\u003eSuperior clutch engagement feel through corners — prevents the front end from tucking as the clutch closes\u003c\/li\u003e\n\u003cli\u003eDiaphragm spring design prevents pressure plate wobble, resulting in a smoother, more progressive lever release\u003c\/li\u003e\n\u003cli\u003eSignificant rotating mass reduction of approximately 0.7–0.8 kg, directly improving throttle response and handling agility\u003c\/li\u003e\n\u003cli\u003ePatented ball-ramp mechanism governs the anti-hopping function with pin-sharp accuracy at high engine speeds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003ePatented Ball-Ramp Technology\u003c\/h2\u003e\u003cp\u003eAt the heart of the STM FBM-S020 sits a patented ball-ramp assembly — the defining element that separates this clutch from simpler slipper designs. Under hard deceleration the ramps separate the clutch plates progressively, metering the degree of engine braking in real time rather than applying a blunt, fixed reduction. The result is a rear tyre that stays planted and steerable rather than locking and skipping, giving the rider meaningful feedback and genuine control through the braking zone.\u003c\/p\u003e\u003ch2\u003eWeight and Rotating Mass\u003c\/h2\u003e\u003cp\u003eShedding approximately 0.7–0.8 kg from the drivetrain's rotating assembly has a disproportionate effect on a high-revving inline-four. The S1000RR responds to throttle inputs more sharply, direction changes feel lighter, and the engine climbs through its rev range with noticeably less mechanical inertia. On circuit, that translates to faster lap times; on road, it means a more alert, involving riding experience.\u003c\/p\u003e\u003ch2\u003eBuild Quality and Engineering\u003c\/h2\u003e\u003cp\u003eSTM manufactures slipper clutches to the standards demanded by professional road-racing teams across Europe. Every component in the FBM-S020 is precision-machined to tight tolerances, ensuring consistent clutch behaviour from the first session to the hundredth. The diaphragm spring eliminates the pressure-plate float that can introduce inconsistency into the clutch feel, so the lever response remains predictable whether the engine is cold or fully up to temperature.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThe STM FBM-S020 is a direct fitment for the following motorcycle:\u003c\/p\u003e\u003cul\u003e\u003cli\u003eBMW S1000RR — K46 chassis, model years 2009 to 2018\u003c\/li\u003e\u003c\/ul\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eAttribute\u003c\/th\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eSTM\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart number\u003c\/td\u003e\n\u003ctd\u003eFBM-S020\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003eSlipper clutch (anti-hopping clutch)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFitment\u003c\/td\u003e\n\u003ctd\u003eBMW S1000RR K46 (2009–2018)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eKey mechanism\u003c\/td\u003e\n\u003ctd\u003ePatented ball-ramp anti-hopping system\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSpring type\u003c\/td\u003e\n\u003ctd\u003eDiaphragm spring\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight saving\u003c\/td\u003e\n\u003ctd\u003eApprox. 0.7–0.8 kg vs. OEM assembly\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"STM","offers":[{"title":"Default Title","offer_id":53168705372426,"sku":"FBM-S020","price":1028.05,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/FAP-S040.png?v=1780811702","url":"https:\/\/inter-pace.com\/products\/stm-slipper-clutch-bmw-s1000rr-k46-fbm-s020","provider":"Inter-Pace","version":"1.0","type":"link"}
