Kawasaki claims their Ninja ZX-10R is “the middleweight sportbike that won just about every magazine comparo,” so let’s just see what the magazines have to say regarding to it: "...the new ZX-6R blew everyone out of the water this time. Not only did it turn the quickest lap time, but every rider who finished riding the Kawasaki at the end of a session had nothing but praise for the little green Ninja in nearly every aspect of performance." – sportrider
"This extremely capable all-around package proved to be number one in our outright Superpole Session lap times by a tenth of a second over the race-bred Yamaha." – motorcycle-usa
“Strong bottom- and mid-range, together with a screaming top end, makes the Ninja second only to the 675 Daytona in terms of engine satisfaction.” – superbike"The 2009 ZX-6R is the most powerful standard 600 MCN has ever tested with a beasty 115bhp at the back wheel." – MCN
"...the ZX has proved it’s as good as it gets in the 600cc category. Combining class-leading power with a highly responsive and trustworthy chassis are the major elements of the formula for middleweight class success." – motorcycle
