CLASS-LEADING ENGINE PERFORMANCE

Kawasaki takes 400cc-class engine performance to a new level, achieving an unprecedented 56.7 kW (77 PS) of power with Ram Air. The howl of the engine as it revs beyond 15,000 rpm adds to rider exhilaration. A quick-revving nature and direct throttle response are complemented by a flexible character that offers strong low- to mid-range torque for city riding, as well as screaming high-rpm power ideal for sport or track riding.

ULTRA-COMPACT NIMBLE SUPERSPORT CHASSIS

A hallmark of the ZX series is razor-sharp handling with excellent feedback that inspires confidence, and the Ninja ZX-4R is no exception. This stems directly from Kawasaki's WorldSBK racing efforts, and their work in developing the Ninja ZX-10R and Ninja ZX-6R. As a result, the Ninja ZX-4R offers a handling character similar to its siblings.
