More cooling performance for your Yamaha R3 – perfect for street, track & racing
The Yamaha R3 is a popular lightweight sportbike: agile, rev-happy, economical – but under sporty riding conditions, high ambient temperatures, or track use, the stock cooling system quickly reaches its limits. The result: rising water temperatures, loss of power, or increased wear.
The H2O Performance auxiliary water cooler effectively expands the cooling system of the R3 and creates additional thermal reserves. The engine remains stable in the optimal temperature range, operates more efficiently, and easily withstands higher loads.
