Overview[edit | edit source]
Kawasaki Z 400J
The Kawasaki KZ400-J had an air-cooled four-cylinder, four-stroke, eight-valve DOHC engine, and six-speed gearbox derived from the larger Kawasaki Z500/Z550. The KZ400J was produced from 1980-1983. The "West Germany" version was limited to 25 kW. These bikes were electric start only, and the KZ400-J had a single (US model) or double (UK, Western Germany models) disc brake at the front, and a drum brake rear.
The 1980 model was identified as Kawasaki KZ400-J1, while in 1981 the Kawasaki KZ400-J2 was introduced with small differences, like a transistorised ignition system.
