The patented ball-ramp system that controls the anti-hopping function is manufactured to tight tolerances, ensuring consistent, repeatable behaviour whether the clutch is cold on a morning warm-up lap or at operating temperature deep into a race session. The diaphragm spring — a design choice that distinguishes STM units from conventional slipper clutches — actively prevents pressure plate wobble, giving riders a level of lever feel rarely found even on factory-prepared machines.\u003c\/p\u003e\u003ch2\u003ePerformance \u0026amp; Handling Gains\u003c\/h2\u003e\u003cp\u003eThe weight saving of approximately 0.7–0.8 kg in rotating mass is not merely a paper figure. On the MV Agusta F3 675, where the engine sits centrally and its rotational inertia influences chassis dynamics, shedding that mass from the clutch assembly noticeably sharpens throttle response and reduces the gyroscopic effect through direction changes. Combined with the slipper mechanism's ability to modulate rear wheel slip rather than simply cutting it, this clutch lets riders trail-brake deeper and carry greater corner-entry speed with real confidence.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eThis STM slipper clutch is a direct replacement unit specifically developed for the MV Agusta F3 675 across all model years from 2011 through to 2026 (part number FMW-S040).
