When it comes to performance, no class is more competitive than middleweight sportbikes. To stand out in this crowd, a motorcycle needs to do everything better than well it needs to kick serious tail in every department. Hats off to the Kawasaki Ninja® ZX-6R then, winner of 600cc comparison tests in just about every publication and website of note on the planet. With an engine the critics agree feels bigger than 599cc, and a chassis that out handles all others, the ZX-6R returns as the bike to beat in 2010.
