This 1999 KTM 250 SX is being dismantled at Derrimut. It’s a liquid-cooled two-stroke motocrosser with upside-down forks, disc brakes and a chassis built purely for the track – by the late 90s KTM’s motocross range was becoming genuinely competitive with the established Japanese brands, and this bike is a good example of that era of development.
Parts off this 250 SX
- Cylinder barrel, head, piston and power valve components
- Reed valve assembly, carburettor and airbox
- Expansion chamber and silencer
- Gearbox internals and clutch assembly

Two-stroke motocrossers this age get raced hard and crashed often, which keeps demand for genuine used parts steady among racers who’d rather not chase increasingly scarce new-old-stock items through a dealer. This is a common source for a full top-end rebuild or a single bolt-on replacement after a get-off.
Everything is a used take-off, checked over before sale – never new, never boxed as genuine. We freight Australia-wide from our Derrimut yard.
