DescriptionThe whole story▼
Born from collaboration with championship-winning teams including Puccetti Racing, Barni Racing, Go Eleven and MV Agusta Reparto Corse, the Febur FE1258S Racing Kit radiator for the BMW S1000RR K46 carries genuine motorsport heritage into every session. Its refined surface architecture and premium construction keep coolant temperature locked in the optimal 75–80°C window, eliminating the thermal drift that robs the S1000RR inline-four of its peak output.
Key Features
- Holds coolant temperature in the ideal 75–80°C range, preventing overheating and power loss under sustained track conditions.
- Engineered surface structure maximises heat dissipation area for consistent, stable thermal regulation lap after lap.
- Premium materials selected specifically for racing durability — built to endure the thermal cycling and vibration of competition use.
- Developed alongside and proven by leading World Superbike and Supersport teams: Puccetti Racing, Barni Racing, Go Eleven and MV Agusta Reparto Corse.
- Direct replacement fitment for the BMW S1000RR K46 across the full 2009–2018 model range — no modification required.
Race-Proven Design and Heritage
Febur's reputation has been forged in the most demanding racing series in the world. The FE1258S is not an aftermarket upgrade dressed in motorsport language — it is the product of genuine data gathered by factory-supported teams pushing S1000RRs to their absolute limits. The improved core geometry draws on that experience, moving coolant more efficiently and shedding heat faster than the OEM unit even when ambient temperatures or engine load spike during close racing.
At the heart of the Febur philosophy is temperature stability rather than simply lower temperatures. Sudden thermal swings are as damaging to consistent power delivery as outright overheating. By maintaining the coolant in the narrow 75–80°C band, the FE1258S allows the engine management system to operate with the precise, predictable inputs it was mapped for — translating directly into repeatable, exploitable power on every exit.
Build Quality and Finish
Febur radiators are constructed from high-grade materials chosen for both thermal conductivity and long-term resilience. The finish is purposeful and track-focused, consistent with the aesthetic language of a machine built for the circuit. Every unit is assembled with the attention to detail demanded by teams where a single DNF due to overheating is unacceptable.
Fitment and Compatibility
The Febur FE1258S Racing Kit radiator is designed exclusively for the BMW S1000RR (chassis code K46) across all model years from 2009 to 2018. It is a direct-fit component requiring no cutting, drilling or bracket fabrication.
