About the Kawasaki KZ305
A KZ305 parts guide organized by model suffix and repair, with the different A- and B-model year applications set out below.
KZ305 engine, brake and fuel-system parts have different application boundaries. The engine gasket set below names KZ305A, KZ305B, KZ305C and KZ305D for 1981–1982. Clutch, caliper and petcock listings then divide into narrower model and year combinations. Start with the repair and complete suffix rather than carrying the gasket set’s range across the motorcycle.
Choose the KZ305 suffix before the repair
Use KZ305A parts for the listed 1981–1982 engine, clutch, caliper and fuel-tap repairs. The KZ305B parts page separates 1987–1988 fuel parts from the clutch plate’s 1982 application and the caliper kit’s 1983 application. Base KZ305 fork seals and rear brake shoes remain available through the repair links on this family page.

Identify your motorcycle before orderingKZ305 identification checklist
Keep the frame and engine records together. Confirm the model year using documentation that matches the motorcycle’s market and full model designation.
- Record the complete frame number and model designation from the motorcycle and its documents. Keep every suffix letter.
- Record the engine marking separately, particularly if the engine has been replaced.
- Photograph the carburetor markings, brake caliper and fuel-tap mounting before comparing parts.
- For fork seals, compare the removed seal markings and dimensions with the product listing. Confirm model year using market-specific documentation.
Contact PartsNMore with clear photos of the frame and engine markings and the component you need. Include any known replacements or modifications.
