High-revving Performance
With a redline beyond 15,000 rpm indicating its screaming potential, this engine features racing-inspired technology also found on the Ninja ZX-10R. The high revs deliver a distinctive, exhilarating engine sound characteristic of a high-performance Kawasaki In-Line Four.
Enhanced Power. Distinctive ZX Look
Complementing the centrally positioned Ram Air intake, the side Ram Air duct, designed with feedback from the Ninja H2, routes air to the air cleaner box and contributes to stellar performance. Its aggressive look and intake sound add to the screaming In-Line Four experience, and visually identify the bike as one of Kawasaki's Ninja ZX models.
World Superbike Inspired Chassis Design
Key chassis dimensions (centre of gravity position, swingarm pivot position, engine axis positions, caster angle, etc) were inspired by Kawasaki's World Superbike Ninja ZX-10RR racer, bringing WorldSBK chassis design thinking to the 400cc class.
Trellis Frame with Optimised Rigidity Balance
Designed using Kawasaki's advanced dynamic rigidity analysis, this trellis frame made from high-tensile steel delivers the required balance of strength and chassis flex to achieve the Ninja ZX-4R's nimble supersport-style handling.
