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.

Benefits of the high-performance water cooler

• Massively increased cooling power thanks to a larger surface area and racing fins

• Stable coolant temperature even under heavy load or high ambient temperatures

• Optimal thermal reserve for spirited country roads, long tours, or trackdays

• Consistent engine output without heat-related power dips

• Less thermal wear, increasing engine service life

• More efficient operation, especially at high RPM and aggressive riding style

• Ideal for tuned or race-oriented R3 setups

This upgrade makes your Yamaha R3 noticeably more powerful and more reliable.
