The Kawasaki GPZ550 was a in-line four, four-stroke Sport/Touring motorcycle produced by Kawasaki between 1981 and 1990. It could reach a top speed of 122 mph (196 km/h). Max torque was 35.4 ft/lbs (48.0 Nm) @ 8000 RPM. Claimed horsepower was 63.56 HP (47.4 KW) @ 10500 RPM.
Engine
The engine was a air cooled in-line four, four-stroke. A 58.0mm bore x 52.4mm stroke result in a displacement of just 553.0 cubic centimeters. Fuel was supplied via a double overhead cams/twin cam (dohc).
Drive
The bike has a 6-speed transmission.
Chassis
It came with a 100/90-18 front tire and a 120/80-18 rear tire. Stopping was achieved via dual disc in the front and a single disc in the rear. The front suspension was a Telescopic fork while the rear was equipped with a Swingarm. The GPZ550 was fitted with a 4.76 Gallon (18.00 Liters) fuel tank.
History
The ZX550A was marketed in the US as the Kawasaki GPz550.
Kawasaki's first GPz550 of 1981 was not only the half-pint brother to the firm's GPz1100 muscle bike, it was also a mould-breaking machine in its own right. Until then, four-cylinder 550s (which at the time was the preferred middleweight capacity, the vogue for 600s didn't start until 1986) were general-purpose roadsters, with no particular performance emphasis. That changed with the mean and moody, black and red GPz.
When first revealed, it caused quite a stir 53bhp was quite something from a middleweight in those days. And even thought the little GPz relies on air-adjustable forks and twin-shock rear suspension (an even racier Unitrack version followed in 1983), it's still a nippy urban tool that will happily keep up with the more modern stuff if the right hands.

Introduced in 1981, the Kawasaki GPZ 550 was an upgrade of the KZ 550 street bike, with a hot-rodded version of the old machine’s four-cylinder engine, an air-charged fork, adjustable shocks and a bikini fairing. This was the first of the line, with a 500 cc DOHC engine, later bored out to 553 cc's and also available as the 398 cc Z400J (identical to the Z 550).
