All-New In-Line Four Engine

The new 399 cm3 liquid-cooled DOHC In-Line Four engine pushes technological boundaries to comfortably top the 400cc class*. Developed with know-how gained from other Ninja ZX models, the high-performance engine offers class-leading power and a rev-range that extends beyond 15,000 min^-1.

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 front forks include adjustable spring preload.

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.

Performance & Sound

Header pipes and collector pipe layout were inspired by the exhaust of the Ninja ZX-6R. Joint pipes link the headers, contributing to strong power output and meeting emissions and sound regulations.

High-Performance Supersport Brakes

The 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.

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.

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.

Integrated Riding Modes

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.

MODEL VARIATIONS

The Ninja ZX-4R SE, with original KRT-inspired colour and graphics, higher-grade front fork with adjustable spring preload, and equipped with a number of accessories, is also available in certain markets.

Accessories equipped on the Ninja ZX-4R SE include:

- Dual-direction KQS

- smoked windshield

- USB outlet

- frame sliders

- adjustable spring preload front fork

KAWASAKI QUICK SHIFTER (SE MODEL)

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 quick and easy deceleration.

* During acceleration, the system detects that the shift lever has been actuated and sends a signal to the ECU to cut ignition so that the next gear can be engaged without having to use the clutch.

* During deceleration, the KQS system automatically controls engine speed, allowing riders to downshift without operating the clutch.

* KQS does not function below 2,500 min^-1.

* The system uses a contactless-type sensor, offering very high reliability.
