Description

The JM Race Large WSS600 Water/Oil Radiator is engineered for the Yamaha R6 models from 2008-2026, offering superior cooling performance for competitive and hobby circuit riding. Designed for optimal heat management, this radiator ensures your engine operates at peak performance, especially during demanding conditions like Endurance races, NW200, and the TT Isle of Man, as utilized by racers like Michael Dunlop and Sandro Corese. The system integrates a water-cooled upper radiator with a bottom oil cooler, providing significantly higher efficiency than stock water coolers. The main advantage of this integrated design is its ability to maintain stable oil temperatures, crucial for extending the life of engine components such as the head gasket and camshafts, particularly for high-RPM engines frequently used on tracks. This JMRaceradiator kit includes all necessary components for installation: an aluminum adapter with o-rings, stainless steel oil hose connections for self-assembly, fittings, aluminum cooling water tubes, blue silicone hose, hose clamps, and a 1.5 bar radiator cap. Assembly is described as easy, with all mounting parts included. PLEASE NOTE: This radiator is not compatible with the original exhaust system; it requires the Akrapovic Evolution Racingline exhaust. Due to the specialized nature and potential for custom tuning, it is recommended to contact JM Race for advice on selecting the best radiator for your specific driving style, competitive level, and engine modifications. The product comes with a 1-year warranty, and delivery time is approximately 8-16 weeks after payment.
