Without doubt, this supercharged machine—in track-only H2R form or as a street-legal H2 model—is at the top of our must-ride list. Simply put, no other production motorcycle is supercharged, and we absolutely need to feel the otherworldly accelerative effects of that chain- and gear-driven blower, which spins at 10 times the speed of the crankshaft and transforms this new-from-the-ground-up Kawasaki into a bona fide 200-plus-mph machine. A full suite of electronics will keep that front wheel on the pavement, while top-notch suspension and brakes will undoubtedly do their best to give these heavy H2s an agility that suitably complements their insane straight-line abilities.
