More cooling performance for your Yamaha R6 – ideal for sporty riders
The Yamaha R6 RJ15 (2008–2016) is known for its rev-happiness, high engine power, and uncompromising sportiness. However, with intensive use – sporty country roads, narrow mountain passes, hot summer days, or track sessions – the stock cooler quickly reaches its limit. The result: rising temperatures, power loss, or thermal stress.
The H2O Performance auxiliary water cooler provides a solution here. It expands the cooling capacity of the stock cooler, drastically improves heat dissipation, and ensures that your R6 remains reliably within the optimal temperature range even under extreme conditions.
Advantages of the auxiliary water cooler
-
Massively increased cooling performance thanks to enlarged cooling surface and optimized fin structure
-
Significantly more stable coolant temperature, even with intensive sporty riding
-
More thermal reserve for hot days, high RPMs, or long sessions
-
Protection against overheating & heat buildup, ideal for aggressive riding styles and track use
-
Improved engine performance & smoother power delivery, as the engine does not hit the temperature limiter

If you push your R6, this upgrade is a real performance boost.
