2015 Kawasaki Ninja ZX™-6R 30th Anniversary, THEY ARE HERE! NEW 2015 NINAs - New 30th Anniversary model celebrates three decades of Ninja dominance. Thirty years ago, the Kawasaki 600 Ninja literally invented the 600 cubic centimeter supersport segment, which today remains one of the benchmark performance classes in the world. Now for 2015, Kawasaki celebrates three decades of racing wins and championships with a very special 30th Anniversary Ninja ZX-6R, the ultimate expression of the Ninja’s “Forever Fearless” attitude in the middleweight sportbike class. Building on the current ZX-6R platform, the 2015 edition features exclusive styling touches that uniquely identify it as the powerful descendant of the motorcycle that truly started it all.
