MCN has scooped spy photos of the 2013 Kawasaki ZX-6R, reporting that it returns to 636cc, but is otherwise mostly a restyle of the existing bike. 600cc supersport sales have collapsed in the global market, essentially halting development in the class. But, Kawasaki appears to be attempting to keep the current model fresh with aggressive new styling and that bigger motor. Will it be the first Japanese supersport to come fitted with traction control? That, plus these killer new looks would really set it apart from its other long-in-the-tooth competitors.
