Maximum thermal performance for the latest R1 generation

The Yamaha R1 RN32/RN49 (2015–2019) is a high-tech superbike with an extremely powerful engine, fast electronic systems, and high thermal demands. Especially during aggressive street riding, high ambient temperatures, or fast track sessions, the stock water and oil cooler quickly reaches its limits.

The H2O Performance water + oil cooler kit replaces the OEM system with a high-performance combination of an enlarged water cooler and an efficient oil cooler. Result: significantly lower temperatures, maximum stability, and an engine that consistently delivers full power even under extreme conditions.
