Kawasaki Motors Australia has confirmed that it will release the new Ninja ZX-4R and Ninja ZX-4RR to local showrooms in the third quarter of 2023, following the all-new model’s reveal overnight.

Both versions are motivated by a 399cc inline four-cylinder engine that can rev beyond 15,000rpm, and weigh in at a healthy 188 kilograms (wet). Kawasaki has yet to officially confirm engine outputs, however, INFO MOTO understands that it produces more than 58kW (78.9hp) of power.

The base Kawasaki Ninja ZX-4R and its higher-spec ZX-4RR sibling do not meet LAMS certification in Australia despite falling under the maximum 660cc displacement limit. Pricing for Australia has yet to be confirmed.

The use of a four-cylinder engine represents a return of the high-performance low-capacity sportsbike segment, making it the only of its kind locally. The bike builds on the brand’s ZX-25R, which is not available in Australia, with increased output and complimenting chassis and electronic upgrades.

In standard guise, the bike features four rider modes to toggle three-level traction control and power mode settings, a colour dash with smartphone connectivity and twin LED lighting.

Suspending the front-end is a set of 37mm upside down front forks, however, stepping up to the range-topping ZX-4RR variant brings preload adjustable Showa forks and a higher-spec rear shock derived from the ZX-10R litre-class sportsbike.

Also unique to the top-spec variant is a standard-fit up/down quickshifter, a TFT dash and racey ‘KRT’ graphics. The base ZX-4R is exclusively finished in Metallic Black paint.

Both the ZX-4R and ZX-4RR feature 290mm front brake discs and a 220mm disc at the rear, a 15-litre fuel tank and have a seat height of 800mm.

The standard fitment of 17-inch wheels measuring 120/70 and 160/60 front-to-rear should provide access to a strong selection of sports and track tyres.

Learner riders will continue to have access to the LAMS approved Ninja 400 and Ninja 650 models in Australia.
