DescriptionThe whole story▼
The K&N KN-204-1 racing oil filter is engineered specifically for the Yamaha YZF-R1 and YZF-R1M across chassis codes RN32, RN49 and RN65 (2015–2026). Whether you are covering daily miles on the road or pushing hard on track, this filter delivers reliable, high-flow filtration and the structural integrity your crossplane four-cylinder deserves — without complicating your service routine.
Key Features
- 17 mm hex nut allows fitting and removal with a standard socket — no strap wrench or specialist tools required, keeping service intervals quick and straightforward.
- Hex nut includes a safety-wire drilling, meeting scrutineering requirements for closed-circuit and track-day use.
- Pre-lubricated O-ring seals correctly from the first fitting, reducing the risk of leaks and cutting workshop time.
- Anti-drain-back valve prevents dry starts after the engine has been sitting, protecting bearings at every cold start.
- New overpressure relief valve combined with a reinforced base plate and double-rolled seam ensures the filter holds its integrity under the sustained high oil pressures generated at racing speeds.
- Wall thickness increased by 50% over standard filters, giving outstanding resistance to stone strike damage and deformation on track.
- Advanced synthetic filter media offers high flow rate alongside excellent filtration efficiency, and is fully resistant to racing fuel contamination.
Built for the Road, Ready for the Track
K&N designed the KN-204-1 to serve riders who use their YZF-R1 or R1M in more than one environment. On the road, the anti-drain-back valve and pre-greased O-ring mean every cold start is properly protected and every oil change takes minutes rather than a messy struggle. On track, the safety-wire hole in the hex nut satisfies the wire-locking requirements common at circuit events, and the reinforced casing shrugs off the debris and pressure spikes that would compromise a standard filter. The synthetic media keeps oil clean under sustained high-rev running, so your crossplane engine stays protected lap after lap.
