About the Kawasaki KX250
Find the right generation of Kawasaki’s two-stroke motocross parts.
The KX250 name covers decades of Kawasaki motocross development. This guide focuses on classic two-stroke applications, including the liquid-cooled J and K series. Earlier KX250 fork parts and later two-stroke carburetor kits also appear here, so the parent page is a starting point for several generations.
KX250J, KX250K and KX250L parts by year
The J branch covers the 1992 J1 and 1993 J2. Featured K-model clutch, petcock and rotor applications run from 1994–1998; the corresponding L applications run from 1999–2002. Fork bushings have narrower coverage. Use the branch comparisons below to keep those differences visible while building a repair order.
