In September 1971 the H2 was a direct result of the success of the 500 cc Kawasaki H1 Mach III introduced in 1969. The H2 engine was a 3-cylinder two-stroke with an engine displacement of 748 cc (45.6 cubic inches) which produced 74 horsepower (55 kW) at 6,800 rpm, a power-to-weight ratio of 1 hp (0.75 kW) to every 5.7 lb (2.6 kg) of weight.
The H2 750 was introduced in 1971, the culmination of Kawasaki's two-stroke project. Kawasaki said of the bike, "It's so quick it demands the razor-sharp reactions of an experienced rider."

Kawasaki already had the largest-displacement Japanese machine with their 650 cc four-stroke W series, [1] but it did not fit the niche Kawasaki was aiming for. Honda had introduced its Honda CB450 in 1965 and in 1969, the Suzuki T500 Titan/Cobra appeared. Also in development was the Yamaha XS 650.
