We’re wrecking this 1998 Yamaha YZ125 at Derrimut. It’s a liquid-cooled two-stroke motocrosser with upside-down forks, disc brakes and an aluminium-braced swingarm – by the late 90s a thoroughly developed race bike, and the parts coming off it are all built for hard track use rather than trail riding.
Parts off this YZ125
- Cylinder barrel, head, piston and power valve components
- Reed valve assembly, carburettor and airbox
- Expansion chamber and silencer
- Gearbox internals and clutch assembly
- Inverted forks, triple clamps and wheels
- Swingarm, rear shock and linkage
- Front and rear brake calipers, discs and master cylinders

Two-stroke motocrossers this age get raced and crashed hard, which keeps demand for genuine used parts steady from racers who’d rather not pay dealer prices for a bike that’s out of production. Parts off this bike also suit other YZ125 model years from the same design generation, either side of 1998, which widens your odds of a straight-fit replacement.
