About the Kawasaki KZ440
Compare KZ440 models, identify your motorcycle and find parts by repair.
Kawasaki’s KZ440 family combines a SOHC parallel twin and six-speed gearbox with several chassis layouts. The A LTD has cast wheels, a stepped seat and chain final drive. The B is the simpler standard with spoked wheels and drum brakes at both ends. The C has cast wheels and a front disc; the D LTD uses a rear-wheel belt. The 1982 G1 follows the D4 layout with different handlebars, seat and fuel tank.
Start with the model, then the repair
For an intake repair, the featured carb kit lists A/D 1980–1983 and G 1982; the stock-airbox filter lists B 1980–1981 and C 1981. Front-caliper kits split A/D 1980–1982 from A/D 1983 and G 1982. Use the repair links below for these applications and the model guide to compare the chassis.

Record the complete frame marking and engine number. A replacement engine can have a different identity from the frame, while changed carburetors, brakes and forks need their own identification.
How to read this chart: These are reference starts from factory model sheets, with the trailing continuation mark omitted. They are not complete production ranges or a VIN decoder and do not establish part interchange.

Original-market names include Z440 and KZ440. Alternative market and plant entries are not all reproduced here. The B1 frame entry is cropped, and the D5/D6 sheets repeat their starts; use the complete vehicle markings and documents to resolve those cases.
Keep the full suffix, year and original market with your notes. Photograph the fitted component and compare its markings, dimensions and listed application before ordering.
