The middleweight sportbike that won just about every magazine comparo! 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 600 cubic centimeter comparison tests in just about every publication and website of note on the planet. With an engine the critics agree feels bigger than 599 cubic centimeters, and a chassis that out handles all others, the ZX-6R returns as the bike to beat in 2010.
