The Kawasaki GPz750 Turbo was a sportbike manufactured from 1983 to 1985.
Although carrying GPz badges on the engine covers, it was only referred to by Kawasaki as the "750 Turbo" - the GPz tag wasn't mentioned. Development started in January 1981 as a turbocharged 650, then as a 750 from November 1981. When finally released, the stock bike made a claimed 112 hp , had sports bike handling (for the day) and looked good - especially next to the other factory turbo bikes which were already on the market - the Suzuki XN85, Honda CX500 and CX650 turbos, and the Yamaha Seca Turbo. Performance was on a par with the GPz1100 , at around 11.2 seconds at 125 mph for the quarter mile and 148 mph flat out. One magazine even branded it the fastest bike they had ever tested, and Kawasaki ran some ads claiming it to be "The Fastest Production Motorcycle in the World". Jay "PeeWee" Gleason also recorded a 10.71 quarter for Kawasaki to show that the turbo had genuine performance and was ahead of the other factory turbos. It is widely considered to be the "best" factory turbo produced by the Japanese manufacturers.
It is widely perceived that the Kawasaki turbo was simply the addition of fuel injection and a turbocharger to a standard GPz750 motorcycle engine. This is far from the case, as almost every component was changed or strengthened for this bike and almost no major parts are interchangeable.
