The U.S.A. was the world’s largest motorcycle market in the mid-1960s, and many American enthusiasts coveted lively, powerful machines with sporty handling. While Harley-Davidson focussed on big, soft cruisers, Japan answered the call. Kawasaki developed the H1 Mach III, an inline three-cylinder two-stroke which it intended should be the king of the 500s; ambitiously, it aimed for a 60hp machine that could run the quarter-mile in thirteen seconds. When it arrived in 1969, Cycle World ran it to 119.14mph and a 13.2sec quarter. The model evolved through the alphabet, culminating in the H1F of 1975, while the H1R racing variant proved formidable in Grands Prix.
This 1975 H1F was imported and registered in Britain in 2018, and promptly sold to the vendor, who began a comprehensive overhaul, including a repaint from Brown to Green, extensive rechroming and a full engine refurbishment by Firefox Racing. The carburettors were reconditioned by Motocarb, the frame was powder-coated, the seat was refurbished and a multitude of new parts were fitted including Higgspeed expansion chambers, electronic ignition units, fork seals, tyres and tubes, stainless-steel spokes, chain and sprockets, shock absorbers and fuel tap. The vendor advises it has only covered thirteen miles since completion, so some final tuning-up will be required, and the chain guard is supplied but requires repairs.
