Engineered specifically for the Yamaha YZF-R3 across model years 2019 to 2026, it smooths out every downshift on your favourite back road just as effectively as it does on a circuit, giving you more confidence the moment you tip into a corner.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003ePrevents engine over-rev on downshifts, keeping the rear wheel planted and the chassis composed during braking\u003c\/li\u003e\n\u003cli\u003eReduces rear-wheel hop to deliver improved traction and stability under hard deceleration\u003c\/li\u003e\n\u003cli\u003eSignificantly lowers the trigger impulse of a highside, making spirited riding meaningfully safer\u003c\/li\u003e\n\u003cli\u003eAllows controlled rear-wheel slides — a natural advantage for both track days and flowing road sessions\u003c\/li\u003e\n\u003cli\u003eImproves clutch closure control mid-corner, preventing the bike from tucking the front under load\u003c\/li\u003e\n\u003cli\u003eDiaphragm spring design smooths the feel at the lever and eliminates pressure-plate wobble for a cleaner release\u003c\/li\u003e\n\u003cli\u003ePatented ball-ramp mechanism governs the anti-hopping function with precision at high rpm\u003c\/li\u003e\n\u003cli\u003eApproximately 0.7–0.8 kg reduction in rotating mass, noticeably sharpening throttle response and overall performance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eEveryday Usability\u003c\/h2\u003e\u003cp\u003eWhere many slipper clutches are designed purely for the pits, the STM FYA-S180 is equally at home on a Sunday morning ride. The progressive engagement means town traffic and slow-speed manoeuvring feel natural rather than snatchy, while the weight saving keeps the YZF-R3 feeling nimble and responsive from the moment you pull away. Installation uses the existing basket architecture of the R3, so the learning curve is manageable for a competent home mechanic.\u003c\/p\u003e\u003ch2\u003eTechnology \u0026amp; Build Quality\u003c\/h2\u003e\u003cp\u003eSTM's patented ball-ramp system is the heart of the unit. Under normal throttle-on conditions the ramps lock the clutch pack in full engagement, transmitting drive cleanly. As soon as engine braking forces reverse through the drivetrain — during a rapid downshift or a missed gear — the ramps disengage proportionally, limiting the torque spike that would otherwise spin the rear tyre or snap the chassis sideways. The diaphragm spring replaces the conventional coil-spring stack, producing a more linear lever pull and removing the risk of pressure-plate flutter at sustained high rpm. Every component is manufactured to STM's exacting tolerances, reflecting decades of Italian motorsport engineering applied to a machine that punches well above its displacement.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eThis clutch is a direct-fit replacement designed exclusively for the Yamaha YZF-R3 covering model years 2019 through 2026. No modifications to the engine cases or clutch basket are required. Always verify your specific model year against the part number FYA-S180 before ordering.\u003c\/p\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eBrand: STM\u003c\/li\u003e\n\u003cli\u003ePart number: FYA-S180\u003c\/li\u003e\n\u003cli\u003eType: Slipper clutch (anti-hopping clutch)\u003c\/li\u003e\n\u003cli\u003eFitment: Yamaha YZF-R3 (2019–2026)\u003c\/li\u003e\n\u003cli\u003eOperating 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 reduction in rotating mass\u003c\/li\u003e\n\u003cli\u003eCountry of manufacture: Italy\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STM","offers":[{"title":"Default Title","offer_id":53168706584842,"sku":"FYA-S180","price":1028.05,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/FDU-S050_9e14dd83-34ce-4296-8b13-53bf785570c1.png?v=1780811770","url":"https:\/\/inter-pace.com\/products\/stm-fya-s180","provider":"Inter-Pace","version":"1.0","type":"link"}
