DescriptionThe whole story▼
Born on the World Supersport grid and refined through seasons of hard racing, the Febur FE1579S combined water and oil cooler brings genuine championship-proven thermal management to the Yamaha YZF-R6 RJ27. Trusted by GMT94, Puccetti Racing, Barni Racing, Go Eleven and MV Agusta Reparto Corse, this is the cooler that elite teams reach for when engine temperatures decide race results.
Key Features
- Drops coolant temperature by 15–20°C compared to the standard radiator, keeping the engine firmly in its optimal thermal window throughout a session.
- Weighs just 2.6 kg — a precision-engineered aluminium construction that adds capability without unnecessary mass.
- Enhanced surface geometry maximises heat dissipation even under sustained high-load conditions on track.
- Proven across multiple seasons in the World Supersport Championship with front-running factory-supported teams.
- Eliminates power loss from heat soak, delivering consistent peak output lap after lap rather than a gradually diminishing curve.
- Direct-fit design engineered specifically for the RJ27 chassis — no fabrication or adaptation required.
Heritage & Design
Febur has built its reputation supplying the paddock's most demanding teams, and the FE1579S reflects that lineage at every level. The cooler's core architecture features an expanded heat-exchange surface that goes well beyond the OEM specification, while the overall profile is tailored to sit cleanly within the RJ27's fairing envelope. This is not a universal part adapted to fit — it is a component conceived alongside the motorcycle's thermal and packaging constraints, which is precisely why the world's fastest Supersport squads choose it over the alternatives.
Performance on Track & Road
Maintaining stable coolant temperatures across a full race distance is one of the clearest marginal gains available to any serious R6 pilot. As engine temperatures climb beyond the ideal range, ignition timing is pulled, fuelling richens and power drops — effects that compound over the course of a session. The Febur FE1579S arrests that decline, holding temperatures steady so the ECU never needs to intervene defensively. The result is a motorcycle that feels as strong on the final lap as it did at the start.
Installation Notes
Before fitting, verify oil pressure is within specification. Due to the technical nature of this installation — which involves both the coolant and oil circuits — fitting by a qualified workshop is strongly recommended.
