2011 Kawasaki Ninja ZX-14, A Pinnacle Performer and Worthy Successor to the Legendary Z-1A Pinnacle Performer and Worthy Successor to the Legendary Z-1 For more than 40 years, Kawasaki has shocked and awed the motorcycle world with its big-bore streetbikes. From the arm-stretching 500 cubic centimeter H1 of 1969 to the legendary 903 cubic centimeter Z-1 of 1973, and from the high-tech Ninja ZX-10s and -11s of the 14680's and 14690's to the sublime ZX-12s and -14s of the new millennium, Team Green has continuously kicked butt and taken names in the large-displacement sportbike category.
