1. Kawasaki H2 750
The H2 Mach IV was a 750 cc 3-cylinder 2-stroke production bike built by Kawasaki. It was a Kawasaki triple sold from September 1971 through 1975. A factory produced H2 was able to run a quarter mile from a standing start in 12 seconds and it handled better than the Mach III that preceded it. In September of 1971, the H2 was a direct result of the success of the 500 cc Kawasaki H1 Mach III that was introduced in 1969. Unlike the H1, the 750 had much lower engine speed torque, with a strong burst of power starting at 3,500 rpm and redlines 7,500 rpm.
