More cooling power for your Yamaha R3 – perfect for road, track & racing

The Yamaha R3 is a popular lightweight sportbike: agile, rev-happy, and fuel-efficient – but with a spirited riding style, high outside temperatures, or track use, the stock cooling system quickly reaches its limits. The result: rising coolant temperatures, power drop, or increased wear.

The H2O Performance auxiliary water cooler effectively expands the R3’s cooling system and creates additional thermal reserves. The engine stays stable within the optimal temperature range, runs more efficiently, and handles higher loads with ease.

Benefits of the auxiliary water cooler

• Significantly increased cooling performance thanks to additional radiator surface area

• More stable coolant temperature, even during intensive sporty use

• More thermal reserve, ideal for trackdays, racing setups, or hot summer days

• Less heat buildup & consistent power – the engine runs reliably and cleanly

• Protection against thermal wear, improved durability of seals & components

• Better rideability, since the engine doesn’t “fall off” even at high RPM

• Perfect for tuned or race-oriented R3 setups

Whether road, daily commuting, sport, or the racetrack – your Yamaha R3 stays noticeably cooler and therefore more powerful.

Who is this kit ideal for?

• Riders of the Yamaha R3 who ride it aggressively

• Trackday riders & newcomers to motorsport

• Commuters, touring riders, and anyone who rides in high temperatures

• Owners of tuned or power-upgraded R3 models
