About the Kawasaki EX305B GPz305
A focused EX305B guide for gaskets, friction parts and clutch springs.
The 1983 Kawasaki parts catalog links EX305-B1 with the GPz305 name. Use the B designation when checking parts on this page, particularly if an earlier repair introduced components from another EX305 version. The frame record and fitted assembly should agree before a standard application is used.
An EX305B brake repair order needs separate checks for the rear drum shoes and the disc-caliper pads. Both links below list 1983–1985. Engine resealing and clutch-spring work use different listings with a 1983 application, so keep those limits in view when combining several jobs into one order.

The table contains EX305B applications only. The selected 1983 engine gasket and clutch spring kits should not inherit the brakes’ 1983–1985 coverage. Also check whether a brake product is for the fitted rear hub or disc caliper.

Identify the fitted equipmentConfirm your EX305B repair application
- Confirm EX305B and the year from the frame identification and matching GPz305 model documentation.
- Match the engine gasket set contents to the engine joints being opened and the selected 1983 application.
- For clutch springs, compare free length, dimensions, count and pressure-plate arrangement with the correct service specification.
- Identify rear drum shoes separately from disc pads; compare the fitted hub or caliper and original friction components.
