While the chassis has received a few minor alterations, including slightly altered damping in the nonadjustable, 37mm conventional fork, it’s a familiar experience. Kawasaki says 379 pounds ready to ride (4.5-gallon fuel tank full), some 22 lbs. more than the CBR250, but that difference is in the noise: First and lasting impressions are of a delightfully featherweight bike, with a compact riding position and near-instant steering response. If you’ve been riding one of those overweight liter-class supersports, the Ninja feels almost ridiculously small and light. Like you could hoist it over a curb with one hand, maybe clean-and-jerk it over your head. Specs watchers will carp about the greater seat height of the Ninja compared to the Honda (all of 0.4 in., at 30.9 in.) but the cut of the Kawasaki’s seat ensures flat-footing at stops yet preserves comfort.
