2013 Kawasaki Ninja 300, 2013 Kawasaki® Ninja® 300 After years of unchallenged domination, the best-selling Ninja® 250R sportbike had finally begun to see competition from other manufacturers. Make no mistake, it still outperformed the challengers by a significant margin on the open road, but why simply outperform them, when you can totally dominate? The new 2013 Ninja® 300 thoroughly dominates its lightweight sportbike competition on the performance front, and it also significantly ups the ante for refinement, ease of use and overall practicality. Thanks to a new digital fuel injection system, and a new F.C.C. clutch with assist and slipper functions, this new 300 is the best lightweight sportbike, by far, when it comes to overall performance and sporting capability.
