The Kawasaki Z650 (known as KZ650 in North America) was produced as a 652 cc (39.8 cu in) standard motorcycle by Kawasaki from 1976 until 1983. It had a four-cylinder four-stroke, DOHC, air-cooled, wet sump engine positioned across the frame with two valves per cylinder and a five-speed gearbox. Designed as a middleweight version of the Kawasaki Z900, the similar-styling had "an attenuated version of the traditional Kawasaki tail fairing".[3] It competed in the market against the smaller SOHC Honda CB650. The Z650 was the epitome of the "Universal Japanese Motorcycle" (UJM).[1][4]

It press-debuted in late 1976 when six US-specification machines were air-shipped from the Akashi works to the UK distributor near London, prior to the London Motorcycle Show. The bikes were assembled and road-shipped to Edinburgh, Scotland, by Kawasaki UK's road race transporter, to be road-tested by 30 assembled European journalists.[5][3]
