Engineered specifically for the 1299 platform, this clutch eliminates rear-wheel hop under hard downshifts, minimises highside risk at high speeds, and shaves approximately 0.7-0.8 kg of rotating mass from the drivetrain — all in a direct OEM-replacement package carrying part number FDU-S050.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003ePrevents engine over-revving on downshifts, keeping the rear tyre planted and the chassis stable through corner entry\u003c\/li\u003e\n\u003cli\u003eReduces rear-wheel hop for measurably improved traction and stability under hard braking\u003c\/li\u003e\n\u003cli\u003eMinimises the trigger impulse of a highside, significantly lowering risk at racing speeds\u003c\/li\u003e\n\u003cli\u003eAllows controlled rear-wheel slide for confident, sport-oriented cornering\u003c\/li\u003e\n\u003cli\u003eImproved clutch closing-phase control in corners prevents unwanted tucking of the front end\u003c\/li\u003e\n\u003cli\u003ePatented ball-ramp technology governs the slipper function with precision at high engine speeds\u003c\/li\u003e\n\u003cli\u003eDiaphragm spring eliminates pressure-plate wobble, delivering a cleaner, more progressive lever feel\u003c\/li\u003e\n\u003cli\u003eWeight saving of approximately 0.7-0.8 kg through reduction of rotating mass improves throttle response and overall performance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eEngineering Behind the STM Slipper Clutch\u003c\/h2\u003e\u003cp\u003eSTM's patented ball-ramp mechanism is the heart of the FDU-S050. Under normal acceleration the ramps lock the clutch basket solidly, transmitting full engine torque to the rear wheel without slip or power loss. The moment the engine begins to over-run on a downshift — a scenario that sends stock clutches into a chattering, wheel-hopping frenzy — the ramps disengage proportionally, allowing the clutch to slip just enough to smooth out the drivetrain spike. The result is a rear tyre that stays in contact with the track surface instead of skipping off it.\u003c\/p\u003e\u003cp\u003eThe integrated diaphragm spring prevents the pressure plate from teetering under high-rpm conditions, translating directly into a clutch lever pull that feels linear and predictable rather than vague or snatchy. Riders stepping from a standard wet clutch to the STM unit consistently report that the feedback through the lever alone justifies the upgrade.\u003c\/p\u003e\u003ch2\u003ePerformance on Track and Road\u003c\/h2\u003e\u003cp\u003eOn the circuit, the FDU-S050 transforms the Panigale 1299's corner-entry behaviour. Carrying more speed deeper into braking zones becomes viable because the chassis remains settled; highside moments that previously lurked at the edge of the envelope are substantially defused. The weight reduction of approximately 0.7-0.8 kg from rotating mass is not a marketing abstraction — lower rotational inertia means the engine revs more freely, responds faster to throttle inputs, and returns to idle more crisply between gear changes. For riders chasing lap times or simply wanting a more connected, less stressful experience in sport riding, the cumulative effect is real and immediately noticeable.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThis slipper clutch is engineered as a direct replacement for the following models:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eDucati Panigale 1299 (2015-2018)\u003c\/li\u003e\n\u003cli\u003eDucati Panigale 1299 S (2015-2018)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eSpecification\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\u003eFDU-S050\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\u003eDucati Panigale 1299 \/ 1299 S (2015-2018)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSlipper mechanism\u003c\/td\u003e\n\u003ctd\u003ePatented ball-ramp 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 (rotating mass reduction)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIntended use\u003c\/td\u003e\n\u003ctd\u003eTrack and sport road riding\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"STM","offers":[{"title":"Default Title","offer_id":53168705798410,"sku":"FDU-S050","price":1028.05,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/FDU-S050_de82b46d-da1e-4e5a-a399-abeba4c977a8.png?v=1780811728","url":"https:\/\/inter-pace.com\/products\/stm-slipper-clutch-ducati-panigale-1299-s-fdu-s050","provider":"Inter-Pace","version":"1.0","type":"link"}
