Its lightweight-optimised construction delivers noticeably more direct response, smoother gear changes and real-world stability that you feel on the very first hard stop into a corner.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eLightweight wet slipper clutch design reduces rotational mass for quicker, more responsive engagement\u003c\/li\u003e\n\u003cli\u003eControlled back-torque management minimises rear wheel hop under aggressive downshifting\u003c\/li\u003e\n\u003cli\u003eMore stable corner entry — improved confidence when late-braking and leaning hard\u003c\/li\u003e\n\u003cli\u003eSTM Racing technology maintains consistent performance under sustained thermal load\u003c\/li\u003e\n\u003cli\u003eEngineered specifically around the CP4 inline-four of the RN65 generation\u003c\/li\u003e\n\u003cli\u003eEqually suited to spirited road riding, trackdays and club-level competition\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eEveryday Usability Meets Racing Technology\u003c\/h2\u003e\u003cp\u003eThe FYA-S171 sits in STM's SBK Racing Light range — a line designed to bring Superbike Championship-derived slipper clutch technology within reach of serious road and trackday riders without demanding a full race-team budget. The wet clutch architecture means it runs reliably in the standard oil bath of your R1, so there is no need for additional hardware or exotic lubricants. Installation follows OEM mounting points, keeping the upgrade accessible even outside a professional workshop.\u003c\/p\u003e\u003cp\u003eWhere many slipper clutches focus purely on outright track performance, the SBK Racing Light series is calibrated to remain predictable and manageable in mixed-use conditions. The result is a clutch that earns its keep on a Sunday morning canyon run just as readily as it does on a circuit pit-lane exit.\u003c\/p\u003e\u003ch2\u003ePerformance on Road and Track\u003c\/h2\u003e\u003cp\u003eThe reduced rotational inertia of the lightweight basket and plate assembly translates directly into a more agile-feeling machine — the R1 responds crisper to throttle inputs and feels noticeably lighter to flick between direction changes. Under hard braking and rapid downshifts the slipper function progressively releases excess back-torque, smoothing the transition and keeping the rear tyre planted rather than skipping. The outcome is a measurable gain in braking stability, corner-entry confidence and the ability to get on the throttle earlier and with greater precision.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eYamaha YZF-R1 RN65 (2020–2026)\u003c\/li\u003e\n\u003cli\u003eYamaha YZF-R1M RN65 (2020–2026)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eBrand: STM\u003c\/li\u003e\n\u003cli\u003ePart number: FYA-S171\u003c\/li\u003e\n\u003cli\u003eSeries: SBK Racing Light\u003c\/li\u003e\n\u003cli\u003eType: Wet slipper clutch (anti-hopping clutch)\u003c\/li\u003e\n\u003cli\u003eFitment: Yamaha YZF-R1 \/ R1M RN65, 2020–2026\u003c\/li\u003e\n\u003cli\u003eEngine compatibility: CP4 inline-four\u003c\/li\u003e\n\u003cli\u003eMounting: OEM mounting points, direct replacement\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STM","offers":[{"title":"Default Title","offer_id":53169032888586,"sku":"SY-STMANTIH-65C156-01","price":2218000.0,"currency_code":"MWK","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/FDU-S050_bac7c3b0-1a7f-4c94-bb6d-778fd36d5353.png?v=1780819777","url":"https:\/\/inter-pace.com\/en-mw\/products\/stm-sbk-racing-slipper-clutch-yamaha-yzf-r1-r1m-rn65-fya-s171","provider":"Inter-Pace","version":"1.0","type":"link"}
