How much power does the 2023 Kawasaki Ninja ZX-4RR make?


Kawasaki made headlines with its Ninja ZX-4RR announcement last year. The return to the small-bore four-cylinder brought back memories of Japanese manufacturers who competed in the All Japan TT F3 Championship. This all-new model from Team Green takes inspiration from the unattainable racebikes of the late ‘80s and early ‘90s and applies it to a roadworthy sportbike in an accessible package. The 2023 Kawasaki Ninja ZX-4RR was the winner Cycle World’s Ten Best Lightweight Streetbike for 2023. It’s for a good reason. The 399cc DOHC, liquid-cooled inline four offers a rev range that is unmatched by any other lightweight motorcycle: 16,000 rpm. (Just over 15,000 in the US).

There are four riding modes: Sport (road), Rain (rain), and Rider. The first three ride modes are pre-set for power and traction controls, while Rider allows the user to select between full power or low power as well as three levels of control. A bidirectional quickshifter is also included as standard equipment. The chassis is made up of a high-tensile frame in steel, a 37mm Showa Separate function Big Piston fork, with spring preload adjustment, and an adjustable Showa balance free rear cushion shock. The 2023 Kawasaki Ninja ZX-4RR was 418 pounds before it hit our Dynojet250i dynamometer.
