More cooling performance for the legendary Crossplane R1

The Yamaha R1 RN22 (2009–2014) is one of the strongest character superbikes ever – the Crossplane engine delivers brutal torque, a unique feeling, and enormous heat generation. During sporty street riding, longer sessions, or track usage, the stock cooling system quickly reaches its thermal limits.

The H2O Performance supplementary water cooler expands the OEM cooling system with an additional, highly effective cooling unit. The result: significantly more stable temperatures, less thermal stress, and consistent performance even when you push your RN22 to the limit.

Your advantages at a glance

• Massively increased cooling performance due to additional radiator surface

• Significantly more stable coolant temperature, even under high loads and hot ambient temperatures

• More thermal reserve for aggressive country road riding, track training, or long stints

• Protection against overheating, less power loss, and reduced thermal wear

• More consistent throttle response & cleaner power delivery, as the engine does not operate at temperature limits

• Higher reliability, especially under Crossplane-typical continuous loads

• Ideal for tuned, racing-oriented, or heavily used RN22 models

This supplementary kit is perfect for these riders

• Owners of a Yamaha R1 RN22 (2009–2014)

• Sport riders, track day enthusiasts & ambitious street riders

• Riders who need stable performance under heat or high loads
