2003 Kawasaki Ninja ZX-6R User Ratings

Indeed, the new Kawasaki ZX-6R isn't a 600 at all. While other manufacturers build middleweight sportbikes to fit Supersport regulations, the brain trust at Kawasaki figured a street rider has no such limitations. An extra 37cc may not sound like much, but the new 636cc Kwacker provides a dose of power that will likely surpass the other contenders in the class.
