2013 Kawasaki ZX-6R, Bigger is definitely better when it comes to engine displacement in the middleweight supersport class.  Kawasaki is once again convinced that formula is the ticket to sales sucess in a market segment in which only European manufacturers have recently been willing to take risks.  In the case of the 2013 ZX-6R, the modest bump in engine displacement from 599 to 636cc feels like all the difference in the world when you open the throttle.  To help its product stand out in a class inhabited by so many strong contenders, Kawasaki not only bumped up displacement but also totally revised the twin-beam aluminum chassis and introduced the most sophisticated electronics package found on any Japanese supersport.  Check it out at Brennys Motorcycle Clinic in Bettendorf, Ia.  Call 563-359-7222.  Call for current rebates.
