For riders who use their machine hard on the road or at track days, the stock cooling system can struggle to keep temperatures in check — and that is exactly where the H2O Performance additional water radiator kit earns its place. This is a practical, everyday upgrade that extends the OEM cooling circuit with a high-efficiency supplementary radiator, delivering noticeably more stable coolant temperatures without removing or replacing the original unit.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eSignificantly increased cooling capacity through additional radiator surface area, directly reducing heat soak on hard runs\u003c\/li\u003e\n\u003cli\u003eStabilises coolant temperatures under sustained load, in hot ambient conditions and during stop-and-go riding\u003c\/li\u003e\n\u003cli\u003eRetains the original OEM radiator — the kit installs as an addition, not a replacement, preserving the factory setup\u003c\/li\u003e\n\u003cli\u003eOptimised fin geometry engineered for maximum heat dissipation across a wide range of riding conditions\u003c\/li\u003e\n\u003cli\u003eRace-proven aluminium construction — robust, lightweight and suited to both road and track use\u003c\/li\u003e\n\u003cli\u003ePrecision fit for the Yamaha R1 RN22 (2009–2014): no modification to the frame or bodywork required\u003c\/li\u003e\n\u003cli\u003eIdeal for modified, tuned or hard-ridden RN22 models where thermal headroom is critical\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eBuilt for the Crossplane R1's Real-World Demands\u003c\/h2\u003e\u003cp\u003eThe RN22 generation R1 is one of the most characterful superbikes ever produced. The crossplane crank delivers a riding experience unlike anything else, but it also places sustained thermal demands on the cooling system — particularly during aggressive back-road riding, extended track sessions or slow-speed traffic in warm weather. H2O Performance addresses this directly: the kit expands the cooling circuit with a second high-performance aluminium radiator unit, giving the engine substantially more thermal reserve.\u003c\/p\u003e\u003cp\u003eThe practical result is an engine that runs measurably cooler and more consistently. Coolant temperature spikes under full throttle are reduced, power delivery becomes more linear because the engine is no longer approaching thermal limits, and long-term engine wear is lowered. For RN22 owners who already run a power upgrade, remapped fuelling or track-focused modifications, the additional cooling capacity is not a luxury — it is a sensible prerequisite.\u003c\/p\u003e\u003ch2\u003eWhat You Notice After Fitting\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eLower, more stable coolant temperatures across all riding scenarios\u003c\/li\u003e\n\u003cli\u003eFewer temperature spikes under full-throttle acceleration or in slow traffic\u003c\/li\u003e\n\u003cli\u003eMore consistent power output without heat-related drops\u003c\/li\u003e\n\u003cli\u003eSmoother, calmer engine behaviour and improved rider confidence\u003c\/li\u003e\n\u003cli\u003eReduced long-term thermal wear and greater engine longevity\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWho This Kit Is For\u003c\/h2\u003e\u003cp\u003eThis upgrade is a sound investment for any Yamaha R1 RN22 owner who rides with intent.
