Kawasaki GPz 750

The GPZ750 was introduced in 1982, and then underwent some significant changes in 1983. The original was based on the 1981 KZ750, which was the quickest machine of that year. For 1982 changes included new carbs, cams and mufflers. In 1983, the engine was modified further, mostly in the combustion chamber, and an all new frame was utilized with uni-track suspension. There were also modifications to the suspension, brakes and wheels, as well as the bodywork. The bike become more sport oriented, but lost some of the versatility of the '82. Power in '83 was Auto bhp|85|0@9500 rpm, with torque of 49.7ft·lbf's@7400 rpm. wet weight was Auto lb|515|0's.
