The Kawasaki H2 Mach IV arrived in 1972 as the bigger, faster successor to the already fearsome 500cc H1. Its 748cc 2-stroke triple engine produced around 74 horsepower, delivering it with a notoriously abrupt powerband that earned the bike the nickname 'Widowmaker.' It was one of the fastest accelerating production motorcycles of its time, cementing its legend as a wild and untamed machine.
Collectors prize the H2 for its raw, unfiltered character and its status as a high point for large-displacement 2-stroke street bikes. Before emissions and noise regulations toned things down, the Mach IV offered a sensory experience that's impossible to replicate today. Its reputation for challenging handling only adds to the mystique, attracting riders who want a true 1970s superbike thrill.
