2023 Ninja ZX4RR Launched in USA

The new Kawasaki Ninja ZX-4RR KRT Edition has been officially launched in the U.S. on February 1, 2023. The bike is aimed at riders who crave for high-performance bikes with smaller engine displacements. The ZX-4RR promises to deliver top-of-the-line specifications and features. The New Ninja ZX-4RR is way superior to the old Kawasaki Ninja H2 SX and Ninja ZX 300.

Engine and Transmission

The ZX-4RR is powered by a 399cc liquid-cooled inline-four engine, with a dual overhead cam, four valves, and a compression ratio of 12.6 to one. The engine is capable of producing 26.5 pound-feet of torque at 11,000 rpm and a redline of over 15,000 rpm. The engine is paired with a six-speed gearbox and comes equipped with an assist and slipper clutch.

Suspension and Brakes

The ZX-4RR comes with a 37mm inverted Showa Big Piston Separate Function fork in the front and a horizontal back-link shock in the rear. Both the front and rear suspension have adjustable preload, compression, and rebound damping. The bike is equipped with dual semi-floating 290mm discs in the front and a 220mm petal disc in the rear. The ZX-4RR comes standard with ABS and adjustable brake and clutch levers.

Electronics and Rider Aids

The Ninja ZX-4RR comes with a three-mode traction control system and a power mode that allows riders to choose between full and low power. The bike also comes with four riding modes, a Kawasaki Quick Shifter, and Bluetooth connectivity.

Frame and Dimensions

The frame of the ZX-4RR is inspired by the ZX-10RR and has key dimensions, including the swingarm pivot and center of gravity, taken from the ZX-10RR. The bike is equipped with LED lights, a full-color TFT dash, and a ram air duct. The ZX-4RR has a curb weight of 414.5 pounds, a seat height of 31.5 inches, and a wheelbase of 54.3 inches.
