About the Kawasaki KX125
A repair guide spanning distinct KX125 applications, from early chassis parts to later engine gaskets.
A KX125 restoration and a later-bike engine rebuild can produce very different shopping lists. The collection’s early fork seals and clutch plates, 1980s fuel and brake components, and later gasket set reflect those separate service needs. Keep the bike’s identification with the engine, fork and brake details so each assembly can be matched independently.
Keep early chassis repairs separate from the later gasket set
The featured fork seals list 1978–1979 and the clutch plate 1978–1981. The float valve lists 1982–1987, the pads 1985–1986, and the engine gasket set 1998–1999. These examples support distinct repairs with gaps between them; use the linked product range for the job you are planning.
Know your KX125 before choosing partsKX125 repair checkpoints
Use the checkpoints below to prepare the parts list for your repair.
Early machines
Fork and clutch coverage differ
The fork seals list 1978–1979 while the selected clutch plate lists 1978–1981. A clutch application for 1981 does not establish that year’s fork seal.
1980s service
Check the carburetor and brake separately
The float valve lists 1982–1987, but the featured brake pads list 1985–1986. Confirm the caliper and pad position rather than carrying the carburetor range across.
Later engine work
Keep 1998–1999 gaskets with their listed engine
The selected engine gasket set is listed for 1998–1999. Check the product contents and engine identity; this listing does not provide gaskets for earlier KX125 generations.
Identify your motorcycle before orderingKX125 identification checklist
Record the motorcycle’s identification and check for replacement assemblies before choosing service parts.
- Record the complete KX125 identification and model year from the frame and engine information, especially if an engine has been replaced.
- Identify the carburetor, forks and brake caliper independently; race-bike components may have been changed during earlier repairs.
- Compare gasket outlines, clutch plate profiles and brake pad shapes with the relevant parts diagram before ordering.
