Maximum cooling power for your Yamaha R3 – noticeably more stability & performance
The Yamaha R3 is an extremely popular sportbike—lightweight, eager to rev, and versatile. However, especially with spirited riding, high temperatures, or track use, the stock water cooler quickly reaches its limits. Rising temperatures, loss of output, and thermal stress are the result.
The H2O Performance water cooler kit replaces the OEM cooler with a high-performance aluminum radiator featuring a significantly larger cooling surface and an optimized fin structure. The result: maximum heat dissipation, stable temperatures, and an engine that runs reliably and confidently under all conditions.
