{"product_id":"stm-fya-s190","title":"STM Slipper Clutch for Yamaha YZF-R7 (2021–2026) – FYA-S190","description":"\u003cp\u003eSTM has built its reputation on motorsport-derived clutch engineering, and the FYA-S190 slipper clutch for the Yamaha YZF-R7 is the definitive expression of that heritage. Designed from the ground up for aggressive street and track use, its patented ball-ramp anti-hopping mechanism and diaphragm spring pressure plate bring genuine race-class clutch feel and protection to one of the most exciting middleweight sportsbikes on sale today.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003ePatented ball-ramp technology controls the anti-hopping function precisely at high engine speeds, giving you confidence under hard trail-braking and aggressive downshifts.\u003c\/li\u003e\n\u003cli\u003ePrevents rear-wheel hop and reduces engine over-rev on downshifts, dramatically lowering the risk of a highside and keeping the chassis settled mid-corner.\u003c\/li\u003e\n\u003cli\u003eControlled rear-wheel slide capability — rear-end movement stays managed and predictable rather than sudden, improving corner-entry handling.\u003c\/li\u003e\n\u003cli\u003eDiaphragm spring pressure plate eliminates pressure-plate judder on clutch release, delivering a smooth, progressive feel at the lever that is noticeably more refined than the OEM unit.\u003c\/li\u003e\n\u003cli\u003eSignificant rotating-mass reduction of approximately 0.7–0.8 kg, freeing up engine response and improving overall performance of the YZF-R7.\u003c\/li\u003e\n\u003cli\u003eBetter management of clutch closure in corners prevents the bike from tucking the front under deceleration, adding an important layer of active safety.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eDesign, Finish and Heritage\u003c\/h2\u003e\u003cp\u003eSTM has been supplying slipper clutches to World Superbike and Moto2 teams for decades. The FYA-S190 carries that racing DNA into a bolt-on kit engineered specifically for the YZF-R7 platform. Every component reflects the company's Italian precision manufacturing — close-tolerance machined basket and hub geometry, carefully selected friction and steel plate compounds, and an anodised finish that holds up to repeated high-temperature cycling without degrading. This is not a universal kit adapted to fit; it is a model-specific design matched to the YZF-R7's engine character, gearbox ratios and chassis balance.\u003c\/p\u003e\u003ch2\u003ePerformance on Road and Track\u003c\/h2\u003e\u003cp\u003eOn track the benefits are immediate. Braking deep into corners with the throttle closed, the ball-ramp mechanism progressively disengages drive, preventing the rear tyre from locking and launching the rider over the bars. On the road the same technology translates into a more forgiving, fatigue-free clutch action — useful during technical mountain-road riding where rapid downshifts are frequent. The weight saving from reduced rotating mass sharpens throttle response and improves the revving character of the CP2 parallel-twin engine without any engine modifications.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThe STM FYA-S190 is a direct, model-specific fitment for the following motorcycle:\u003c\/p\u003e\u003cul\u003e\u003cli\u003eYamaha YZF-R7 — model years 2021, 2022, 2023, 2024, 2025, 2026\u003c\/li\u003e\u003c\/ul\u003e\u003cp\u003eNo chassis modifications are required.
