This 1975 Kawasaki H2 Mach IV was acquired in 2025 by the seller, and subsequent service included rebuilding the air-cooled 748cc two-stroke triple with machined cylinder heads, overbored cylinders, and 73.5mm pistons as well as servicing the five-speed transmission. Finished in Candy Red with white, black, and red accents, the motorcycle also features a kick starter, oil injection, a trio of Mikuni carburetors, a chrome three-into-three exhaust system, a front disc brake, wire-spoke wheels, a two-up seat, a rear grab bar, chrome-finished fenders, and both center and side stands. This H2 Mach IV is offered in Canada with an owner’s manual, service records, a handwritten maintenance summary, and Ontario registration in the seller’s name.

The motorcycle is finished in Candy Red with white, black, and red accents. Additional features include an upswept two-up seat, a rear grab bar, a tail cowl, folding passenger foot pegs, chrome-finished fenders, and both center and side stands. The seller notes that a boxed set of Kawasaki mirrors is included in the sale.

Wire-spoke wheels measuring 19″ up front and 18″ out back are wrapped in IRC tires. Suspension consists of a telescopic fork in addition to a pair of preload-adjustable shocks attached to the swingarm. Braking is from a disc up front and a drum out back. The seller states that the front brake master cylinder has been replaced and the brakes have been serviced.

The chrome handlebar is mounted aft of a 140-mph speedometer, a tachometer with a 7,500-rpm redline, and warning lamps. The five-digit odometer shows 4,200 miles, approximately 25 of which have been ridden under current ownership.

The air-cooled 748cc two-stroke triple is equipped with a kick starter, oil injection, triple Mikuni carburetors, and a chrome three-into-three exhaust system, and it produced 74 horsepower when new. A 2025 engine rebuild carried out by Fast by Gast of Grand Island, New York, included replacing the connecting rods, bearings, and various seals as well as machining the cylinder heads, port-matching the intakes, and overboring, honing, and chamfering the cylinders before installing Wossner 73.5mm pistons. The seller notes that the carburetors were synchronized in April 2026, at which time the fuel petcock was serviced, and the oil pump was reportedly overhauled in July 2026.

Power is routed to the rear wheel through a five-speed transmission and a drive chain. A 2025 transmission service by Fast by Gast of Grand Island, New York, is documented in the gallery below.

An owner’s manual is included in the sale along with service records and a handwritten maintenance summary.

This Kawasaki is being sold on its Ontario registration, which serves as the ownership document in Ontario, Canada.
