Kawasaki KDX400 Motorcycle - Dual-Sport (1979-1980)

The Kawasaki KDX400, produced for the 1979 and 1980 model years, was a robust big-bore enduro motorcycle designed for off-road performance. It featured a potent 392cc two-stroke, single-cylinder, air-cooled engine, delivering 39 horsepower (29 kW) at 7000 rpm and 42.2 Nm of torque at 6000 rpm. This engine was paired with a five-speed transmission, a 36mm Mikuni carburetor, and CDI ignition, making it a formidable machine for its era. Both model years were equipped with twin-shock rear suspension and leading-axle air-spring forks. Between its 1979 (A1) and 1980 (A2) model years, the KDX400 saw minimal changes, with core engine specifications remaining consistent. Kawasaki offered the KDX400 primarily as a single model, with the A1 and A2 designations indicating only the model year. There were no distinct trim levels with varying feature sets during its production. The KDX400 was a two-year model, succeeded by larger displacement KDX models like the KDX420 in 1981, marking a generational shift for the KDX line rather than mid-cycle updates for the KDX400 itself.
