DescriptionThe whole story▼

Keeping coolant temperatures stable across a long commute or a full race day is one of the most effective ways to protect engine performance, and the Febur FE1491S supplementary water radiator kit is engineered to do exactly that for the Yamaha YZF-R6 RJ27. Covering model years 2017 to 2026, this kit slots into your daily riding routine just as naturally as it does on a race weekend, delivering consistent thermal management without drama or compromise.

Key Features

  • Optimised surface area draws heat away from the coolant more efficiently than the standard radiator, keeping temperatures in the ideal operating range during stop-start traffic as well as sustained high-speed running.
  • Precision construction from high-quality materials ensures long service life and reliable performance even under the sustained thermal loads of track use.
  • Stable coolant temperatures prevent the gradual power loss that accompanies heat soak, so the engine delivers its full output lap after lap or mile after mile.
  • Direct fitment for the Yamaha YZF-R6 RJ27 (2017-2026) means no fabrication or modification — a straightforward installation using existing mounting points.
  • Race-proven pedigree: Febur cooling products are trusted by Puccetti Racing, Barni Racing, Go Eleven, MV Agusta Reparto Corse and other top-level teams, making this the same technology available to everyday riders.

Everyday Usability

The FE1491S is not a race-only item. On the road, supplementary cooling capacity pays dividends in summer traffic, on motorway runs at sustained high revs, and on back-road blasts where the engine rarely gets a chance to cool. By expanding the total radiator volume, the kit gives the cooling system a meaningful reserve, reducing the frequency and severity of temperature spikes that gradually wear on engine components over time. For riders who use their R6 as a daily machine or weekend sports tourer, that thermal headroom translates directly into peace of mind and lower long-term maintenance costs.

Race-Developed Engineering

Febur designs its radiator kits in close collaboration with WorldSBK and WorldSSP teams who cannot afford a single degree of thermal inconsistency. That development process refines core geometry, tube density and fin spacing until the cooling efficiency is genuinely superior to the original equipment. The FE1491S benefits from the same iterative process, meaning road riders inherit solutions that were stress-tested in the most demanding conditions motorsport can produce.

Fitment & Compatibility

This kit is specifically developed for the following motorcycle:

  • Yamaha YZF-R6 RJ27 — model years 2017, 2018, 2019, 2020, 2021, 2022, 2023, 2024, 2025, 2026
