Kawasaki Ninja ZX-4RR KRT Edition

Kawasaki is introducing a game-changing addition to the 400cc supersport motorcycle category – the all-new Ninja ZX-4RR KRT Edition. This highly focused bike offers riders a thrilling and confident riding experience, with the ability to excel on both the track and the road. The Ninja ZX-4RR KRT Edition is aimed at those seeking a new level of exhilaration on two wheels.

At the heart of the Ninja ZX-4RR KRT Edition is a brand new 399cc in-line four-cylinder engine that delivers an impressive audible signal with its high-performance output, setting it apart from other bikes in its class. The engine was developed with input from the Kawasaki Ninja ZX supersport machines, and offers quick-revving performance with direct throttle response, featuring strong low-to-mid-range torque for city riding and high-end power for track use. The distinctive intake and exhaust notes of a Kawasaki in-line four-cylinder engine add to the overall riding experience.

In addition to the powerful engine, the Ninja ZX-4RR KRT Edition features a lightweight trellis frame that provides a compact and agile ride, enabling exciting cornering performance. Dual front disc brakes, a high-performance Showa SFF-BP front fork, and BFRC Lite rear shock have been fitted to ensure that the bike delivers a superior level of performance from the ground up.


The Ninja ZX-4RR KRT Edition comes equipped with a powerful all-new 399cc liquid-cooled, 4-stroke, in-line four-cylinder engine that is designed to deliver thrilling performance and a fun-to-ride experience. This engine has been developed with feedback from other Kawasaki Ninja ZX supersport machines and boasts a quick-revving nature, along with a direct throttle response that combines strong low-mid range torque for city riding and high-rpm power for track use. The result is an exhilarating surge of acceleration that is accompanied by the unique intake and exhaust notes of a Kawasaki in-line four-cylinder engine.

The liquid-cooled, DOHC, 16-valve engine features a bore and stroke of 57.0 x 39.16mm, which contributes to its impressive top-end power. The engine also packs a punch with its strong torque output. The high-spec ECU, similar to that found on the Kawasaki Z H2, allows for the use of Kawasaki’s latest electronics, including Electronic Throttle Valves (ETV) with 34mm throttle bodies that provide smooth, natural engine response. This is achieved by enabling the ECU to control the volume of both the fuel (via the injectors) and the air (via throttle valves) delivered to the engine.

The ETV also facilitates the use of Kawasaki’s electronic rider support systems, including integrated riding modes with traction control, selectable power modes, and a dual-direction Kawasaki Quick Shifter (KQS) that allows riders to seamlessly shift up or down without using the clutch. With these features, riders can feel at one with their machine and enjoy a thrilling ride every time they hit the road or track.


The Ninja ZX-4RR KRT Edition is equipped with high-performance suspension components that are designed to deliver exceptional handling and stability. At the front, it features a 41mm Showa SFF-BP fork that uses separate functions for each fork leg – one side controls compression damping and the other controls rebound damping. This design allows for easy adjustment of the suspension settings to suit the rider’s preferences and riding style. The fork is also fully adjustable for preload, compression, and rebound damping, providing a wide range of options for fine-tuning the suspension to match different riding conditions.

At the rear, the Ninja ZX-4RR KRT Edition uses a high-performance BFRC Lite (Balance Free Rear Cushion Lite) shock that provides excellent control and stability. The shock uses a unique design that separates the compression and rebound damping circuits, which allows for precise adjustment of the suspension settings. The shock is also fully adjustable for preload, compression, and rebound damping, providing the rider with a wide range of options for tuning the suspension to their preferences.


The Ninja ZX-4RR KRT Edition is equipped with dual 310mm front disc brakes that are gripped by radial-mount monobloc calipers for exceptional stopping power. The rear brake uses a single 220mm disc and a single-piston caliper. Both the front and rear brakes are controlled by a high-performance Nissin master cylinder that provides excellent feel and feedback to the rider.

Wheels & Tires

The Ninja ZX-4RR KRT Edition features lightweight 17-inch wheels that are designed to reduce unsprung weight and improve handling. The wheels are shod with high-performance Bridgestone Battlax Hypersport S22 tires that are specifically designed to provide exceptional grip and handling in both wet and dry conditions. The tires are 120/70ZR17 at the front and 160/60ZR17 at the rear.

Ergonomics & Styling

The Ninja ZX-4RR KRT Edition features aggressive, aerodynamic styling that is inspired by Kawasaki’s Ninja ZX supersport models. The bodywork is designed to reduce drag and provide optimal aerodynamic performance, while also creating a bold and aggressive look that is sure to turn heads.

The riding position on the Ninja ZX-4RR KRT Edition is designed to provide a balance between sporty handling and rider comfort. The footpegs are positioned high and rearward, putting the rider in a sporty and aggressive riding position that is ideal for track riding. The handlebars are positioned lower than on a standard sportbike but are still high enough to provide comfortable ergonomics for street riding.

The Ninja ZX-4RR KRT Edition also features a 4.3-inch TFT color instrumentation that displays a wealth of information to the rider, including speed, rpm, gear position, fuel level, and much more. The instrumentation is also smartphone-compatible, allowing riders to connect their phone to the bike via Bluetooth and access features such as turn-by-turn navigation and music playback.

The Kawasaki Ninja ZX-4RR KRT Edition is a high-performance supersport motorcycle that is designed for riders who demand the best in terms of performance, handling, and style. With its powerful 399cc engine, high-performance suspension, and advanced electronics, the Ninja ZX-4RR KRT Edition is sure to provide an exhilarating riding experience both on the street and on the track. Whether you’re a seasoned track rider or just looking for a high-performance sportbike for weekend rides, the Ninja ZX-4RR KRT Edition is a top contender in the 400cc supersport category.
