The Kawasaki GPz750 was a sport bike introduced by Kawasaki in 1982. It was more than a warmed-over KZ750,[needs context] 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.[1] The GPz750 underwent some significant changes in 1983. The original was based on the 1981 KZ750-E.[2] Kawasaki retired the KZ750 after 1983. The 1983 KZ750L3 was nearly identical to the '82 GPz750, but for different colors, no bikini fairing, and without the porting & polishing in the cylinder head.[3]

What is a Kawasaki NINJA? Kawasaki Ninja ZX-7R Motorcycle: The Kawasaki NINJa ZX-7R sport bike resume speaks for itself. With nine AMA Superbike Championships and a number of victories with Kawasaki Road Racing Eric Bostrom at the helm, the ZX-7R has a history unmatched by any other sport bike. A Rob Muzzy-tuned ZX-7R also carried Kawasaki Drag Racing Rickey Gadson to three AMA/prostar Drag. 1994 Kawasaki ZX7 Ninja L-model rare ZX7R ZX750 ZX-7 ZX-7R - $4000 (Winston Salem) For Sale: 1994 Kawasaki ZX-7 (L-model)Clean and clear NC title in my name.20,098 MilesRare OEM Purple/Black/Pink pain schemeOriginal fairingsExcellent condition for a 23 year old bikeVance and Hines full exhaust system, jet kit, and K&N filterHello all,I am.

In 1983, the engine was modified further, mostly in the combustion chamber, and an all-new frame was used with Uni-Trak suspension. There were also modifications to the suspension, brakes and wheels, as well as the bodywork. The bike became more sport-oriented, but lost some of the versatility of the '82.[needs context]
