KAWASAKI GPZ 750 (1983-1985) Specs, Performance & Photos

The Kawasaki GPZ 750 was a sports motorcycle that debuted in 1982, replacing the KZ750, and manufactured until 1985, when it was replaced by the GPZ 750 R, a liquid-cooled version.

Compared to its predecessor, the GPZ 750 featured several updates that focused on performance. Some changes included tapered bearings in the steering head, a different upper triple clamp with an aluminum clip-on handlebar, and a bikini fairing similar to the one of the GPZ 550.

The bike also got more power with higher compression, valves developed to lift quicker, 34 mm Mikuni carburetors, a new combustion chamber for the cylinder heads with porting and polishing from the factory, and an additional oil cooler.

In 1983, the Japanese motorcycle manufacturer launched the Kawasaki GPZ 750, a sports bike further modified in the combustion chamber. It also received a new frame, Uni-Trak suspensions, and revised brakes, wheels, and bodywork.

In the performance department, the 1983 Kawasaki GPZ 750 had installed underneath its fuel tank a 738cc four-stroke four-cylinder air-cooled engine fed by four Mikuni carbs, delivering 78 hp at 9,500 rpm and 58 Nm (43 lb-ft) torque at 7,000 rpm.

The bike's power was handled by a five-speed manual transmission with a wet multi-plate clutch linked to the rear wheel through a final chain drive, pushing the motorcycle to a top speed of 2017 kph (135 mph).
