Kawasaki H2 MACH 4 750CC TRIPLE 1972 Parts & Accessories

Introduced in 1971 for the 1972 model year, the Kawasaki H2 Mach IV stands as one of the most legendary, high-performance two-stroke motorcycles ever produced. Engineered with a single objective—absolute acceleration dominance over the quarter-mile—the Mach IV was built around an air-cooled 748 cc piston-port inline three-cylinder engine delivering an unprecedented 74 HP at 6,800 rpm. Known for its explosive powerband, distinct three-pipe exhaust, and high-speed wheelie tendencies, the H2 earned a permanent place in motorcycle lore alongside a fierce reputation for extreme handling characteristics that tested even expert riders. Produced through 1975 across four distinct model years (H2, H2A, H2B, and H2C), the Mach IV defined the golden era of Japanese multi-cylinder two-stroke performance before strictly enforced emissions regulations brought the open-class two-stroke era to a close.

Key technical specifications and engineering characteristics of the Kawasaki H2 Mach IV include:

• High-Output 2-Stroke Triple: 748 cc air-cooled, piston-port 3-cylinder two-stroke engine producing 74 HP @ 6,800 rpm and 57.1 lb-ft (77.4 Nm) of torque @ 6,500 rpm
• Quarter-Mile Performance: Capable of standing quarter-mile times in the 12.0-second range at over 110 mph (177 km/h) off the showroom floor, with a top speed exceeding 126 mph (203 km/h)
• Ignition & Fuel Delivery: Capacitor Discharge Ignition (CDI) system paired with three 32 mm Mikuni VM32SC carburetors and Kawasaki's "Injectolube" automatic oil injection system
• Chassis Evolution (1972–1975): Tubular steel double-cradle frame with gradual geometry tweaks across iterations (H2B/H2C extended the wheelbase by 2 inches and modified engine mounts to improve high-speed stability)
• Running Gear & Ergonomics: Single 296 mm hydraulic front disc brake, rear 200 mm internal expanding drum, 5-speed manual transmission, and dual friction/hydraulic steering dampers
