From the Kawasaki Triple Wiki page:

The Kawasaki triples were a range of 250 cc to 750 cc motorcycles Kawasaki exported from 1969 to 1980. The engines were air-cooled, three-cylinder, two-stroke with two exhaust pipes exiting on the right side of the bike, and one on the left. Right from the first triple model, the 1969 Mach III H1 500cc, the motorcycle gained the record for being the quickest for its engine size. Despite having severe handling problems, the machines became extremely popular and fine examples command high prices by collectors today.

Model history

The first Kawasaki triple was the 500 cc H1 Mach III, introduced in late 1968.[1] The original H1 was unique for using a CDI ignition which operated through an automotive style distributor. The H1 offered a high power-to-weight ratio for the time, but had generally poor handling and weak drum brakes front and rear. It was the quickest production motorcycle at the time. When motorcycle journalists[which?] expressed disbelief, Kawasaki suggested they take a new H1 to a dragstrip. Using a regular production model with only 7 miles (11 kilometres) on it, Tony Nicosia, a Kawasaki test rider, ran the quarter mile (402 m) in 12.96 seconds at 100.7 miles per hour (162.1 kilometres per hour) for the press to witness. The official figure was 12.4 seconds by Mike Wenzel—quite believable on a well run in machine.[citation needed] Tony Nicosia set many world records with Kawasaki triples over the following years, including some[which?] land speed records at Bonneville Salt Flats.[citation needed]

In 1972, the 750 cc Kawasaki H2 Mach IV was introduced and was essentially a scaled-up version of the H1 500.[2] A stock H2 was rated at 12.0 seconds for the quarter mile (402 m). Updated with more power and better front disc brakes, the H2 became the undisputed king of the streets,[clarification needed] even beating legendary muscle cars of the era such as the Plymouth Hemi Cuda. It was notoriously dangerous, being prone to up-and-over wheelies and speed wobbles. The dangerous handling characteristics arising from its mediocre frame design caused it to be nicknamed the "Widowmaker" by motorcycle enthusiasts of the 1970s.
