Every component in this kit is manufactured to STM's highest EVO SBK specification, combining precision-machined aluminium with proven anti-hopping technology to deliver a transformation that is as immediately felt through your fingertips as it is heard through the iconic mechanical dry-clutch note.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eComplete dry clutch conversion kit including integrated 48D clutch basket and full friction disc set — everything required in a single package\u003c\/li\u003e\n\u003cli\u003eEVO SBK anti-hopping mechanism dramatically reduces rear-wheel hop under aggressive downshifting, keeping the chassis settled at corner entry\u003c\/li\u003e\n\u003cli\u003eExceptionally direct clutch feel and engagement feedback, giving the rider precise, confidence-inspiring control in all conditions\u003c\/li\u003e\n\u003cli\u003eReduced rotating mass compared to a standard wet clutch assembly, allowing the engine to rev more freely and respond faster\u003c\/li\u003e\n\u003cli\u003eHigher thermal tolerance than a conventional oil-bath clutch, maintaining consistent performance across extended track sessions\u003c\/li\u003e\n\u003cli\u003eAvailable in a choice of standard racing colours (red, black, natural grey, green) at a 10% premium, or fully bespoke custom colour combinations at a 40% premium — ideal for custom builds and show bikes\u003c\/li\u003e\n\u003cli\u003eSTM's EVO SBK platform is their flagship racing line, developed for riders who demand absolute precision and uncompromising performance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eBuild Quality and Premium Materials\u003c\/h2\u003e\u003cp\u003eSTM has built its reputation on the uncompromising quality of its dry clutch systems, and the KTT-04300 represents the pinnacle of that engineering philosophy. The 48D clutch basket is a fully integrated, high-tolerance component machined from premium aluminium alloy, chosen for its exceptional strength-to-weight ratio and resistance to the thermal and mechanical stresses that characterise hard track use. The friction discs are selected to work in harmony with the basket geometry, ensuring consistent bite and progressive engagement regardless of oil temperature — because in a dry clutch system, there is no oil to worry about.\u003c\/p\u003e\u003cp\u003eThe EVO SBK anti-hopping mechanism is the result of years of development in circuit racing. Rather than simply reducing chatter under engine braking, it actively controls the clutch disengagement curve during downshifts, smoothing the drivetrain load spike and allowing the rear tyre to maintain its line with far greater predictability. The result is a corner entry that feels composed and deliberate, not anxious.\u003c\/p\u003e\u003cp\u003eColour choices are not an afterthought. STM anodises and finishes each basket to order, meaning the standard palette — red, black, natural grey and green — arrives with the same attention to surface quality as the mechanical components themselves. If those options do not suit your build, the custom colour programme opens up unique combinations that make the clutch a visual centrepiece as well as a mechanical one.\u003c\/p\u003e\u003ch2\u003eRoad and Track Performance\u003c\/h2\u003e\u003cp\u003eOn the road, the KTT-04300 rewards a confident, sporting riding style. The direct engagement feel sharpens every gear change, and the reduction in rotating mass gives the crossplane four-cylinder engine a noticeably more immediate throttle response. The characteristic mechanical sound that accompanies every shift is the same signature note heard in the Superbike World Championship paddock — a constant reminder of the engineering sitting between the frame rails.\u003c\/p\u003e\u003cp\u003eOn track, the advantages compound. Engine braking forces that would ordinarily destabilise the chassis under late, aggressive braking are absorbed and managed by the anti-hopping system. Lap after lap, corner after corner, the rear wheel behaves predictably, and the rider can focus entirely on line and braking point rather than managing unwanted chassis movement.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThe STM EVO SBK dry clutch kit KTT-04300 is designed for all European-specification Yamaha YZF-R1 and R1M models across the following generations:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eYZF-R1 \/ R1M RN32 (2015–2016)\u003c\/li\u003e\n\u003cli\u003eYZF-R1 \/ R1M RN49 (2017–2019)\u003c\/li\u003e\n\u003cli\u003eYZF-R1 \/ R1M RN65 (2020–2026)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eThis broad fitment range makes the KTT-04300 one of the most versatile EVO SBK kits available for the R1 platform, covering the complete current generation of the model from its crossplane-engine redesign through to the latest production year.\u003c\/p\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eBrand: STM\u003c\/li\u003e\n\u003cli\u003ePart number: KTT-04300\u003c\/li\u003e\n\u003cli\u003eType: Complete dry clutch conversion kit\u003c\/li\u003e\n\u003cli\u003eClutch basket: 48D integrated design\u003c\/li\u003e\n\u003cli\u003eTechnology: EVO SBK anti-hopping\u003c\/li\u003e\n\u003cli\u003eMaterial: Precision-machined aluminium alloy\u003c\/li\u003e\n\u003cli\u003eFitment: Yamaha YZF-R1 \/ R1M RN32 (2015–2016), RN49 (2017–2019), RN65 (2020–2026)\u003c\/li\u003e\n\u003cli\u003eIntended use: Road and track\u003c\/li\u003e\n\u003cli\u003eColour options: Red, Black, Natural Grey, Green (+10%); custom combinations (+40%)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STM","offers":[{"title":"Default Title","offer_id":53169033314570,"sku":"KTT-04300","price":3986.47,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/Screenshot2025-12-11110150.png?v=1780819793","url":"https:\/\/inter-pace.com\/products\/stm-evo-sbk-dry-clutch-kit-yamaha-yzf-r1-m-rn32-rn49-rn65-ktt-04300","provider":"Inter-Pace","version":"1.0","type":"link"}
