Kawasaki Ninja ZX-6R

Kawasaki Ninja ZX-6R is a middleweight supersport bike for riders who want a sharp four-cylinder machine rather than a relaxed street tool. By our assessment, its real appeal is the focused chassis-and-engine package, the kind of thing that makes sense on a twisty road or a track day more than in casual stop-and-go use. The downside comes with that focus: the riding position is committed, the engine wants revs, and slow commuting is not where this class feels generous. In practice it asks for attention and a bit of patience, but rewards smooth inputs with the taut, precise feel people buy a ZX model for. Compared with naked middleweights it is less easygoing and more single-minded; compared with larger superbikes it is a step down in brute force but easier to live with. The number 6 in Kawasaki Ninja ZX-6R is part of the name, and the bike itself is about that in-between supersport space where comfort takes a back seat.
