Engineered from the ground up for track and high-performance road use, this unit actively prevents rear-wheel hop under hard downshifts, neutralises the engine-braking spike that triggers highsides, and shaves 0.7-0.8 kg of rotating mass in a single installation.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003ePatented ball-ramp mechanism controls the anti-hopping function precisely, optimising rear-wheel traction at high rpm and under aggressive trail-braking\u003c\/li\u003e\n\u003cli\u003eEliminates over-revving on downshifts, delivering a stable, composed transition through every corner entry\u003c\/li\u003e\n\u003cli\u003eSignificantly reduces the highside trigger impulse, a critical safety benefit when riding at the limit on track\u003c\/li\u003e\n\u003cli\u003eAllows controlled rear-wheel slide for confident, repeatable corner entries in sport riding\u003c\/li\u003e\n\u003cli\u003eDiaphragm spring design prevents pressure-plate flutter, giving a cleaner, more progressive clutch-release feel at the lever\u003c\/li\u003e\n\u003cli\u003eWeight saving of approximately 0.7-0.8 kg through a substantial reduction in rotating mass, improving throttle response and overall performance\u003c\/li\u003e\n\u003cli\u003eBetter clutch engagement control mid-corner prevents unwanted dive, keeping the chassis balanced through the apex\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eEngineering Detail\u003c\/h2\u003e\u003cp\u003eSTM's ball-ramp system is the heart of the FDU-S070. Under normal acceleration the ramps lock up the clutch pack for full, clean drive. The moment engine braking exceeds a calibrated threshold — on a hard downshift or a snap of the throttle shut — the ramps allow the basket to slip relative to the hub, bleeding off the excess torque before it reaches the rear tyre. The result is a rear wheel that stays planted rather than skipping, and a chassis that remains predictable exactly when precision matters most.\u003c\/p\u003e\u003cp\u003eThe diaphragm spring replaces the conventional coil-spring stack, eliminating the oscillation that causes pressure-plate wobble in stock clutches. Lever feel becomes noticeably lighter and more linear, reducing hand fatigue over a full race distance or a long sporting road ride. The reduced rotating mass also lets the engine rev and respond more freely, a noticeable gain on a motor as characterful as the Panigale 959's L-twin.\u003c\/p\u003e\u003ch2\u003eTrack and Road Use\u003c\/h2\u003e\u003cp\u003eOn track, the FDU-S070 transforms the Panigale 959's corner-entry character. Where the stock clutch can allow rear-wheel hop and mid-corner instability, the STM unit keeps the bike settled and the rider focused on the line. On the road, the same anti-hopping action adds a meaningful layer of safety: a momentary over-aggressive downshift no longer risks an unpredictable rear-wheel reaction. This is a component that earns its place whether the Panigale 959 lives in a race paddock or on demanding weekend roads.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eThis slipper clutch is a dedicated fitment for the following model:\u003c\/p\u003e\u003cul\u003e\u003cli\u003eDucati Panigale 959 (2016, 2017, 2018, 2019)\u003c\/li\u003e\u003c\/ul\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eBrand: STM\u003c\/li\u003e\n\u003cli\u003ePart number: FDU-S070\u003c\/li\u003e\n\u003cli\u003eType: Slipper clutch (anti-hopping clutch)\u003c\/li\u003e\n\u003cli\u003eAnti-hopping mechanism: Patented ball-ramp system\u003c\/li\u003e\n\u003cli\u003eSpring type: Diaphragm spring\u003c\/li\u003e\n\u003cli\u003eWeight saving: approximately 0.7-0.8 kg (rotating mass reduction)\u003c\/li\u003e\n\u003cli\u003eFitment: Ducati Panigale 959, model years 2016-2019\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STM","offers":[{"title":"Default Title","offer_id":53168705569034,"sku":"FDU-S070","price":1028.05,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/FAP-S040_bf9d52e1-2953-4fa3-9c86-7bc00203a09b.png?v=1780811715","url":"https:\/\/inter-pace.com\/it\/products\/stm-fdu-s070","provider":"Inter-Pace","version":"1.0","type":"link"}
