2013 Kawasaki Ninja 300, Quick, Strong, and Easy… The Ultimate Lightweight Sportbike - Quick, Strong, and Easy… The Ultimate Lightweight Sportbike 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, when you can totally dominate? The new 2013 Ninja 300 thoroughly dominates its lightweight sportbike competition on the performance front, while significantly upping 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.
