This 1983 Yamaha YZ125 is being dismantled at Derrimut. It’s a two-stroke motocrosser from the era when Yamaha’s Monocross rear suspension was still setting the pace in the 125 class, built purely for the track with none of the trail-bike concessions you’d find on a road-registered Yamaha of the same period.
Parts off this YZ125
- Cylinder barrel, head, piston and reed valve assembly
- Carburettor and airbox
- Expansion chamber and silencer
- Gearbox internals and clutch assembly
- Forks, triple clamps and wheels
- Monoshock linkage and rear shock
- Front and rear brake assemblies
- Plastics, fuel tank and seat
Early-80s motocrossers like this one are getting genuinely hard to source parts for, with dealer stock long since gone and aftermarket support patchy at best. This donor is a solid option for anyone restoring a YZ125 of this generation to original spec, or keeping one running for vintage motocross competition rather than parking it up in a shed.
