DescriptionThe whole story▼
The Febur FE1586 combined water and oil radiator gives your Yamaha YZF-R1/M RN65 the thermal headroom it needs to sustain peak output lap after lap. Engineered with an expanded core surface and race-proven materials, it holds coolant temperatures firmly in the optimal window so engine performance never wavers — whether you are threading through traffic on a summer commute or pushing hard through the final sector of a circuit.
Key Features
- Combined water and oil cooling in a single race-specification unit, simplifying the cooling system while maximising thermal efficiency.
- Optimised core surface area draws heat away from the engine faster, preventing the gradual temperature creep that robs power on long straights and in heavy traffic.
- Eliminates sudden temperature spikes that cause power fluctuations and accelerated component wear under extreme riding conditions.
- Trusted by leading World Superbike and Supersport teams including Puccetti Racing, Barni Racing, Go Eleven, and MV Agusta Reparto Corse — teams that cannot afford a single degree of thermal instability.
- Precision fitment for the RN65 chassis, allowing straightforward installation without modification to OEM mounting points.
All-Day Performance, Road or Track
Thermal management is rarely glamorous, but it is one of the most consequential upgrades you can make to a high-revving superbike. On the road, a stable coolant temperature means consistent throttle response in stop-and-go traffic and during sustained motorway cruising. On track, where ambient temperatures are higher, brake ducts force hot air across the fairing, and the engine is working near its limit every few seconds, the Febur FE1586 provides a meaningful buffer against the heat saturation that erodes both power and reliability.
Febur's engineering approach centres on increasing effective surface area without compromising flow. The result is a radiator that cools more aggressively without requiring modifications to the coolant pump, fan, or thermostat circuit of the YZF-R1/M RN65.
Race Pedigree
Febur products have been at the heart of competitive paddocks for years. When teams such as Puccetti Racing and Barni Racing need thermal reliability under the most demanding race conditions imaginable, they turn to Febur. That same technology is available for your RN65, giving a road or track machine the thermal stability that professional engineers demand.
