Hailed as an engineering marvel, the Kawasaki Ninja H2R boasts a 998 cc supercharged motor designed by Kawasaki Heavy Industries' Gas Turbine division. The power output is "in the region of 300 horsepower," making it the most powerful motorcycle ever produced. Needless to say, the machine isn't built for the streets. This is strictly a closed-course motorcycle, featuring carbon-fiber bodywork from Kawasaki's Aerospace division, as well as a trellis frame -- a first for Kawasaki -- and sport bike geometry rather than a long wheelbase for straight-line stability.
