Ninja ZX-4RR 2024

Into a category filled with 400cc sport models, Kawasaki introduces a revolutionary Supersport model. The Ninja ZX-4RR mounts a 400cc In-Line Four engine with class-leading performance in a compact chassis. On the track or on the street, experiencing the exhilaration of the Ninja ZX-4RR’s unprecedented power, thrilling high-rpm wail, and its sharp, nimble handing will surely awaken the dormant Supersport within you.

Class-Leading Engine Performance

Kawasaki takes 400cc engine performance to a new level, achieving an unprecedented 57 kW (77 PS)* of power. The howl of the engine as it revs beyond 15,000 min-1 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. *JPN spec homologated figure measured under fixed conditions.

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.

Fierce Ninja ZX Styling

Befitting the most powerful machine in the 400cc class, the Ninja ZX-4R’s aggressive Ninja styling exudes a fierce aura of restrained power and explosive action.

Ergonomics for Control and Comfort

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.

Integrated Riding Mode

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.

Dual-direction KQS (SE/RR)

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.

High-Grade Suspension

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

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.
