The H2O Performance supplementary radiator kit adds a high-efficiency cooling surface directly to the OEM circuit, delivering measurably lower coolant temperatures, greater thermal headroom, and the consistent engine behaviour that serious track riding demands.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eSupplementary high-performance radiator that expands the factory cooling circuit without replacing it\u003c\/li\u003e\n\u003cli\u003eRacing-specification fins engineered for maximum heat dissipation and high coolant flow efficiency\u003c\/li\u003e\n\u003cli\u003eRobust aluminium construction — lightweight and fully race-worthy\u003c\/li\u003e\n\u003cli\u003ePrecision fit for Yamaha R1 RN32 \/ RN49 and R1M, 2015–2019\u003c\/li\u003e\n\u003cli\u003eEliminates temperature spikes during long stints, hot laps, and demanding summer road rides\u003c\/li\u003e\n\u003cli\u003eKeeps the crossplane engine operating within its optimal thermal window across every rev range\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eEngineered for the Track, Proven on the Road\u003c\/h2\u003e\u003cp\u003eThe RN32\/RN49 generation R1 and R1M combine a high-revving crossplane inline-four with sophisticated electronics and aggressive chassis geometry — a combination that generates substantial heat under racing conditions. The H2O Performance kit addresses this directly: by supplementing rather than replacing the OEM radiator, it increases total cooling capacity without disrupting the factory architecture. The result is a demonstrably cooler, cleaner-running engine that recovers faster between sessions and resists thermal-induced power drop-off throughout a full track day.\u003c\/p\u003e\u003ch3\u003eReal-World Gains After Fitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eStable coolant temperatures across all load conditions, including full-throttle exits\u003c\/li\u003e\n\u003cli\u003eFewer temperature peaks during extended high-speed stints\u003c\/li\u003e\n\u003cli\u003eMore consistent power delivery and smoother throttle response\u003c\/li\u003e\n\u003cli\u003eQuieter engine behaviour and shorter thermal recovery time between sessions\u003c\/li\u003e\n\u003cli\u003eSignificantly reduced thermal stress on engine internals, seals, and the wider cooling system\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWho This Kit Is For\u003c\/h2\u003e\u003cp\u003eThis kit is the logical next step for any R1 or R1M owner who regularly attends track days, competes at club or national level, runs a tuned or power-upgraded engine, or simply wants the confidence of additional thermal safety on long, fast road rides.
