The Appeal

The Kawasaki H1 500, better known as the Mach III, is one of the most iconic motorcycles of the 1970s. Its 499cc two-stroke triple earned a fearsome reputation for raw, unfiltered performance, and these air-cooled triples remain highly sought after by collectors and riding enthusiasts alike.

This 1975 example was purchased from a Suffolk motorcycle dealer in 2021 and underwent extensive mechanical refurbishment that same year, covering the engine, forks, brakes, carburettors and wheels. The vendor reports it is in good, unrestored condition and states the engine runs well and feels strong. Prospective buyers should note that the engine and logbook numbers are reported as mismatched due to an older H1-D crankcase being used. Offered with its owner's manual, V5C, MOT certificates and invoices, this Mach III presents an opportunity to acquire a usable example of a celebrated two-stroke triple.
