This late-80s Kawasaki KX80 is being dismantled at Derrimut. It’s a liquid-cooled two-stroke minicross bike, built to bridge the gap between a kids’ bike and a full-size motocrosser, with disc brakes and real suspension travel rather than the softer setup you’d find on a trail-oriented minibike of the same period.
Parts off this KX80
- Cylinder barrel, head and piston
- Reed valve assembly and carburettor
- Expansion chamber and silencer
- Gearbox internals and clutch assembly
- Forks, triple clamps and wheels
- Swingarm, rear shock and linkage
- Front and rear brake calipers, discs and master cylinders
- Plastics, fuel tank and seat
Small-capacity two-stroke motocrossers from this era have been out of production for decades, and genuine dealer parts have all but disappeared, so a running donor like this is one of the few realistic sources for period-correct components. It’s a common choice for parents keeping a junior racer competitive, or collectors restoring one to original spec rather than fitting mismatched later substitutes that don’t quite look right. Vintage motocross clubs running dedicated minicross classes are another steady source of demand for this bike’s parts, particularly plastics and cylinder barrels that are otherwise hard to find in good condition.
Everything listed is a used take-off from this actual bike, checked over before it goes out – never new, never boxed as genuine. We freight Australia-wide from our Derrimut yard. Browse the Kawasaki parts category for more from this era, or see the FAQ page for freight details. Vintage minicross racing has a small but dedicated following in Australia, which keeps demand for genuine period parts steady.
