| | |
| 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.
| |
| The GPz750 underwent some significant changes in 1983. The original was based
| |
| on the 1981 KZ750-E. Kawasaki retired the KZ750 after 1983. The 1983 KZ750L3 was
| |
| nearly identical to the '82 GPz750, but with different colors, no bikini
| |
| fairing, and without the porting & polishing in the cylinder head.
| |
| 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.
