The Hesterberg-Cad\/Cam chain guard for the Yamaha YZF-R1 and YZF-R1M — covering all RN32, RN49 and RN65 variants from 2015 to 2026 — replaces the factory plastic part with a precision CNC-machined aluminium 7075-T6 component engineered to absorb and deflect the forces of a chain break before they reach the engine casing.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCNC-machined from aircraft-grade aluminium 7075-T6 for genuine impact resistance in the drivetrain area\u003c\/li\u003e\n\u003cli\u003eDirectly replaces the OEM plastic chain guard with a precision-fit, structurally superior alternative\u003c\/li\u003e\n\u003cli\u003eProtects the engine casing against heavy damage in the event of a chain break — critical for track use\u003c\/li\u003e\n\u003cli\u003eCovers all Yamaha YZF-R1 and YZF-R1M variants on the RN32, RN49 and RN65 platforms, model years 2015 to 2026\u003c\/li\u003e\n\u003cli\u003eAvailable in natural aluminium finish or black anodised — both options suit track and road builds equally\u003c\/li\u003e\n\u003cli\u003eLightweight at approximately 0.175 kg, adding meaningful protection without unnecessary mass\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhy This Part Matters for Serious R1 Riders\u003c\/h2\u003e\u003cp\u003eRiders who invest in suspension setup, braking systems, tyres and bodywork on their YZF-R1 often overlook the drivetrain protection area — until something goes wrong. At the power levels the R1 and R1M generate, the forces acting on the chain, front sprocket and engine casing during a chain break are enormous. The stock plastic guard offers only token resistance.\u003c\/p\u003e\u003cp\u003eThe Hesterberg-Cad\/Cam chain guard addresses this directly. Precision CNC machining ensures an exact fit to the R1's chassis geometry, while aluminium 7075-T6 — the same alloy used in aerospace and high-performance motorsport components — delivers the structural integrity to genuinely contain a chain strike. Whether you are preparing for a trackday, competing in club racing, or building a performance road machine, this is a detail that earns its place on the bike.\u003c\/p\u003e\u003ch2\u003eBuild Quality and Finish\u003c\/h2\u003e\u003cp\u003eBoth finish options are carefully executed. The natural aluminium version has a clean, machined aesthetic that integrates well with aftermarket engine covers and exposed alloy components. The black anodised version offers an additional layer of surface hardness alongside a discreet, purposeful look. Either way, the anodising — where selected — improves corrosion resistance and surface durability compared to bare alloy.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eThis chain guard is designed and manufactured specifically for the following models:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eYamaha YZF-R1 — RN32 (2015–2016), RN49 (2017–2020), RN65 (2021–2026)\u003c\/li\u003e\n\u003cli\u003eYamaha YZF-R1M — RN32 (2015–2016), RN49 (2017–2020), RN65 (2021–2026)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eImportant: this part replaces the original OEM plastic component.
