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.
02
TFT Colour Instrumentation with Circuit Mode
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.
03
Dual-direction KQS
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.
04
Ram Air Intake
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.
05
Smartphone Connectivity
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.
