The exhaust system configuration contributes to strong power output and features a long silencer that produces a clear, racy exhaust note that can only come from an in-line four-cylinder Ninja supersport machine.

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.

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.

The Ninja ZX-4R’s two ø290 mm front brake discs and radial-mount monobloc calipers provide sure stopping power, while also offering excellent braking feel to inspire confidence both on the track and on the street.

The Ninja ZX-4R’s ø37 mm inverted fork uses SFF-BP internals to deliver both racetrack performance and everyday usability while the Horizontal Back-link rear suspension offers a progressive character. Offering increased adjustability, the Ninja ZX-4RR’s front forks include adjustable spring preload, and it features a Showa BFRC lite rear shock—the same type seen on the Ninja ZX-10R.

Naturally aggressive riding position (more forward-leaning than the Ninja 400’s, but still slightly relaxed) lets riders take advantage of the Ninja ZX-4R’s nimble handling. The fuel tank feels slim, promoting good contact with the bike, while the shape of the firm seat cushion facilitates rider weight shift during sport riding, and is comfortable for longer rides.

The 4.3” all-digital TFT colour instrumentation with selectable display modes (Normal, Circuit) clearly displays the most pertinent information, whether on the street or on the track. Circuit Mode shows the gear position, lap times, and rpm above 10,000 more prominently.

Bluetooth technology built into the instrument panel allows connection to smartphones via the “RIDEOLOGY THE APP” smartphone application, enabling riders to access instrument functions for an enhanced motorcycling experience.

From its twin headlights to its Ninja ZX-10R-inspired taillight, all lighting on the Ninja ZX-4R is LED.

Four integrated riding modes (Sport, Road, Rain or Rider (manual)) make it simple to select a level of traction control and power mode to suit the current riding conditions.

Allowing riders to take even greater advantage of the Ninja ZX-4R’s exhilarating engine character, the quick shifter enables clutchless upshifts and downshifts for seamless acceleration and easy deceleration.
