1974 Kawasaki H2 Mach IV

This 1974 Kawasaki H2 Mach IV was purchased by the seller in 2016, and its odometer now shows 2,900 miles. Finished in Candy Lime, the bike is powered by a 748cc two-stroke triple paired with a five-speed transmission. Equipment includes 19″ and 18″ wire-spoke wheels, a front disc brake, preload-adjustable shocks, a kick starter, a trio of Mikuni carburetors, oil injection, a chrome three-into-three exhaust system, a black two-up seat, and both center and side stands. Service in 2026 included rebuilding the carburetors and front brake, refurbishing the switchgear, and replacing the battery as well as repairing the side stand and rear wiring harness. This H2 Mach IV is offered with a service record and a New Jersey title in the seller’s name that lists the model year as 1975. The bodywork is finished in Candy Lime and is mounted over a black-finished double-cradle frame. Details include a black vinyl-upholstered two-up seat, a chrome front fender and rear grab bar, a 4.4-gallon fuel tank, handlebar-mounted mirrors, and both center and side stands. There is an upholstery repair at the rear of the seat, along with a ding in the front fender. A crack in the side stand was repaired in March 2026. Wire-spoke wheels with 19″ front and 18″ rear chromed steel rims wear Dunlop Gold Seal tires. Braking is from a single disc up front and a drum at the rear. Suspension consists of a conventional telescopic fork as well as dual preload-adjustable shocks mounted to the swingarm. A front-brake overhaul in March 2026 included rebuilding and refinishing the master cylinder and the caliper. Nippon Seiki instrumentation ahead of the chrome handlebar consists of a 140-mph speedometer, a tachometer with a 7,500-rpm redline, and indicator lights. The handlebar switchgear was refurbished in March 2026. The five-digit odometer shows 2,900 miles, approximately one of which was ridden under current ownership. The 748cc two-stroke triple was factory rated at 71 horsepower and 57 lb-ft of torque and features triple Mikuni carburetors, oil injection, a kick starter, and a chrome three-into-three exhaust system. A 2016 overhaul is said to have included rebuilding the crankshaft, and service in March 2026 involved replacing the battery, repairing the rear wiring harness, and rebuilding the carburetors in addition to trimming and cleaning the ends of the float bowl oil return hoses. Scrapes on the lower right-side muffler are depicted in the gallery. Power is routed to the rear wheel through a five-speed transmission and a drive chain. The gearbox oil was changed in March 2026.
