The fastest production motorcycle in the world, the Kawasaki Ninja H2 R, had some pretty humble origins. Given the look of this 1973 H2 Mach IV, it can make you wonder, “how the heck did it manage to pull off a 12-second quarter-mile?”
This lot is a 1973 year model Kawasaki H2 Mach IV, the successor to the brand’s H2 Mach III. Unlike the Mach III, this model came 250 more cubic centimeters but it still kept the three-cylinder layout all done up in a two-stroke package that was all-new and not a bored-up version of the 500cc motor found in the Mach III.
