This 2005 Yamaha WR450F is being wrecked at Derrimut. It’s a carburettor-fed, liquid-cooled four-stroke enduro built off the YZ450F motocross platform, with wider-ratio gearing, softer suspension and a full lighting kit for trail and enduro riding rather than the moto track.
Parts off this WR450F

- Swingarm, rear shock and linkage
- Front and rear brake calipers, discs and master cylinders

Because the WR450F shares its basic engine architecture with the YZ450F motocrosser, a lot of what’s coming off this bike also suits a YZ450F needing a rebuild, and vice versa. That crossover is worth knowing whether you’re chasing a specific bolt-on part or a full top-end for either bike, and it’s a detail plenty of owners don’t realise until they ask.
