The Mach IV was Kawasaki's 750 cc two-stroke triple, the big sibling of the 500 cc H1 and the fastest production road bike of its era. This 1971 bike was loud, smoky and vibration-prone, with short wheelbase handling that was known to tankslap at speed. It was built for acceleration and outright speed rather than comfort.
