DescriptionThe whole story▼
The Yamaha R1 RN22 and its legendary crossplane engine are known for producing enormous torque and equally enormous heat. 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.
Key Features
- Significantly increased cooling capacity through additional radiator surface area, directly reducing heat soak on hard runs
- Stabilises coolant temperatures under sustained load, in hot ambient conditions and during stop-and-go riding
- Retains the original OEM radiator — the kit installs as an addition, not a replacement, preserving the factory setup
- Optimised fin geometry engineered for maximum heat dissipation across a wide range of riding conditions
- Race-proven aluminium construction — robust, lightweight and suited to both road and track use
- Precision fit for the Yamaha R1 RN22 (2009–2014): no modification to the frame or bodywork required
- Ideal for modified, tuned or hard-ridden RN22 models where thermal headroom is critical
Built for the Crossplane R1's Real-World Demands
The 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.
The 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.
What You Notice After Fitting
- Lower, more stable coolant temperatures across all riding scenarios
- Fewer temperature spikes under full-throttle acceleration or in slow traffic
- More consistent power output without heat-related drops
- Smoother, calmer engine behaviour and improved rider confidence
- Reduced long-term thermal wear and greater engine longevity
Who This Kit Is For
This upgrade is a sound investment for any Yamaha R1 RN22 owner who rides with intent. Whether you use your R1 for spirited road riding, regular track days, endurance sessions or a tuned street build, the H2O Performance additional radiator kit provides the thermal buffer the crossplane engine genuinely benefits from. It is equally at home on a standard road bike and a race-prepared machine.
