About this model
About the Kawasaki KZ 400
The Kawasaki KZ400 is an air-cooled 398 cc parallel twin from the mid-1970s. It was designed as an approachable middleweight: compact, conventional and simpler to maintain than Kawasaki’s larger fours. Depending on market and year it appeared as the KZ400, KZ400D or with differing bars and wheel equipment. The engine has calm power delivery, a five- or six-speed gearbox depending on version, and typical classic Japanese ergonomics.
The KZ400 suits riders who want a light, straightforward classic for back roads and hands-on maintenance. Do not expect modern braking, suspension or motorway comfort; its appeal lies in honest mechanical character. Buy the most complete example possible. Original airbox, exhausts and bodywork matter more than shiny but ill-fitting universal parts. Always confirm that it starts cold and that both cylinders run evenly.

Before you buy
What to check before buying
- Check carburettors, intake rubbers and airbox for air leaks and uneven idle.
- Check charging voltage, regulator and connectors for corrosion.
- Test gearbox and clutch under load; worn chain and sprockets can disguise shifting problems.
- Inspect frame, exhaust and wire wheels for rust, especially on long-stored imports.
- Check front brake, master cylinder and fork for seizure or leaks.
