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.

Kawasaki Motorcycle Logo

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.

Know your motorcycle before choosing partsKZ305 model and repair checkpoints

Start with the complete KZ305 designation. The A, B and other catalog entries below have different repair applications.

KZ305A

1981–1982 repair applications

The linked engine gasket set, clutch plate, caliper kit and petcock repair kit list KZ305A for 1981–1982.

Parts checkpoint: Use the KZ305A page to compare those items; check gasket contents and clutch-plate quantity separately.

KZ305B

Different years for different components

The clutch plate lists 1982 and 1987–1988. The caliper kit lists 1983 and 1987–1988, while the float bowl gasket lists 1987–1988.

Parts checkpoint: A year supported by one KZ305B part does not extend the application of another.

Other KZ305 entries

Read the full application line

The fork seal set lists KZ305 for 1981–1988; the brake-pad listing specifies KZ305C for 1981 and KZ305D for 1982.

Parts checkpoint: Match the exact entry and the installed assembly instead of dropping the model suffix.

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.

  1. Record the complete frame number and model designation from the motorcycle and its documents. Keep every suffix letter.
  2. Record the engine marking separately, particularly if the engine has been replaced.
  3. Photograph the carburetor markings, brake caliper and fuel-tap mounting before comparing parts.
  4. For fork seals, compare the removed seal markings and dimensions with the product listing. Confirm model year using market-specific documentation.

Kawasaki KZ305 parts questions

Do KZ305A and KZ305B use the same replacement parts?
Some parts list both models, but the years can differ. The featured petcock kit lists KZ305A for 1981–1982 and KZ305B for 1987–1988. Use the complete suffix and year on each product, including when a replacement engine, carburetor or brake assembly has been fitted.
What size fork seals are listed for the Kawasaki KZ305?
The featured fork oil seal set measures 33 × 46 × 11 mm and lists KZ305 for 1981–1988. Compare those dimensions with the removed seals and fitted fork, especially on a motorcycle with a replacement front end.
Are KZ305 clutch plates sold individually?
The clutch plate featured here is sold individually. It lists KZ305A for 1981–1982 and KZ305B for 1982 and 1987–1988. Match the plate type and stack position, then order the quantity required for your clutch.
Which KZ305 models does the engine gasket set list?
The featured engine gasket set lists KZ305A, KZ305B, KZ305C and KZ305D for 1981–1982. Compare its included-parts list with the joints being opened and identify any additional oil seals or service parts your repair needs.
