Kawasaki H1 500 Mach III

Kawasaki's Mach III H1 500cc triple hit the streets soon after the CB750 but it wasn't the technology which socked everyone between the eyes, it was its unique combination of raw, bad-mannered power and supposedly homicidal handling. Nearly 60bhp was claimed for the Mach III, most of it crammed into a powerband which bit like a starving Mako shark at 6000rpm and ran out just 2000 revs later.

If the performance was supposed to make your hair stand on end, the handling was said to be enough to make it fall out. Bike dubbed the 1972 H1B The Fastest Camel in the World and refused to go near another Mach III for two years. Those were heady days when it was taken for granted that Japanese motor design was far ahead of chassis, tyre and brake technology — H1 freaks probably took the headline as' a backhanded compliment to their taste in machinery.

1969 Kawasaki Mach III 1969 Kawasaki H1 500 Mach III This was the first triple by Kawasaki and along with Honda’s 750 Four released in the same year…changed motorcycling forever. Articles from Cycle Guide, Cycle and Motorcyclist at the time quoted “Kawasaki has one of the most devastating two-wheelers ever to happen on the scene”, “We all wanted one, Kawasaki built performance, and the H1 was the nastiest yet”, “Kawasaki has something to sell to folks wanting a big, fast and nasty streetbike, a big bike that could outrun anything out there and it did just that”. It had and still has the best power-to- weight ratio (public available) of any motorcycle made.

1974-75 Kawasaki H1 500 Mach III 1974-75 Kawasaki H1 500 Mach III Developed from the earlier HI, the original triple of 1969, the KH500 had a piston-ported two-stroke engine in a steel-tube cradle frame. Conventional if rather insubstantial suspension and braking components were marginal on the earlier HI, but improved in later models. Later models also tended to gain weight over the originals, and the engines were re-tuned for less ferocious power. By the late 1970s, the poor fuel consumption, reliability and handling of the triples made them less popular, and they were replaced by newer four-stroke designs.

Two-stroke triple. This model has been said to be a more civilized version of the earlier "Widow Makers" since the addition of a  steering stabilizer and front disc brake.
