It could reach a top speed of 217 km/h / 135 mph. 
 
==Engine==
The engine was a Air cooled cooled Four stroke, transverse four cylinder, DOHC, 2 valve per cylinder. The engine featured a 9.5:1 [[compression ratio]]. 
 
==Chassis==
It came with a 100/90 -19 front [[tire]] and a 130/90 -16 rear tire. Stopping was achieved via 2x 260mm discs in the front and a Single 260mm disc in the rear. The front suspension was a  36mm Air assisted forks while the rear was equipped with a Dual shocks spring preload and rebound damping adjustable. The GPz750 was fitted with a 24.5 Litres / 5.8 US gal fuel tank. The bike weighed just 217 kg / 478.5 lbs. The wheelbase was 1500 mm / 59 in long.

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.
