2013 Kawasaki Ninja ZX-14R, Monster Energy Edition - Superlative Performance: The Quickest and Strongest Sportbike in the World! The massively more powerful, R-designated, Ninja ZX-14R made its debut last year as an almost entirely new motorcycle. It remains on-top for 2013, reigning as the undisputed king of the sportbike world. New optional ABS brakes complement its amazing comfort and usability on the street, and help increase its appeal to a wide range of riders. It has to be tough competing against a machine like the ZX-14R, year after year, and continuous refinements have kept it several steps ahead of the sportbike competition, all while filling enthusiasts’ face shields with wild, ear-to-ear grins.
