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 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.
