The Kawasaki GPz750 was a sport bike introduced by Kawasaki in 1981/1982. It was more than a warmed-over KZ750, as it was improved in many areas, focusing on high-performance. Changes started at the front, with tapered bearings in the steering head instead of the KZ750's ball bearings, and the upper triple clamp was changed also, giving the GPz solid aluminum clip-on handle grips instead of the traditional handlebar. A bikini fairing almost identical to the one on the GPz550 was added too. The GPz750 boasted increased power, with slightly higher compression, and camshafts designed to get the valves to full lift quicker, and fitting Mikuni 34mm carburetors to it for smoother airflow. The cylinder heads were also given a new combustion chamber with a 'squish zone' and porting & polishing from the factory. To maintain reliability oil passages were installed under the pistons for increased cooling, and an oil-cooler was added. The GPz750 was the quickest factory 750, as Cycle World recorded a time of 11.93 seconds at 109.62 mph (176.42 km/h) in the 1/4 mile.
