Kawasaki launched in Europe the brand new 2024 Ninja ZX-4R, its 400cc supersport model, which arrives with a 4-cylinder in-line engine and up to 80 hp to dominate the medium-displacement segment.

After the launch of the Ninja ZX-25R (with 250cc, 4-cylinder engine) in Indonesia in 2021, the company invested and created a spicy 400cc version.

In addition to the ‘standard’ ZX-4R version, the ZX-4R SE (with colors and graphics inspired by KRT, Kawasaki’s factory racing team, plus Quick Shifter, smoked windshield, USB port and frame slider) and the ZX-4RR (top of the line model with everything from the ZX-4R SE plus ZX-10R rear suspension and adjustable front suspension) will be offered.

How is the Ninja ZX-4R

The 2024 Kawasaki Ninja ZX-4R is an all-new motorcycle, not based on the Ninja 400, the brand’s 400cc twin-cylinder. In fact, the chassis is based on the structure of the ZX-25R and is inspired by the chassis elements and design concept of the Ninja ZX-10RR.

It features a high-strength steel trellis frame and a long-type curved swingarm, ensuring optimal front-rear weight distribution, as well as an excellent balance of rigidity and flexibility, providing agile handling and excellent feedback.

The design is very similar to the Ninja ZX-6R, the 636cc and 4-cylinder supersport bike, with very similar fairings and angles. It’s aggressive and high-class modern, inspired by the bigger supersport bikes from the Ninja family.

But, the ‘icing on the cake’ of the 2023 Ninja ZX-4R is its 399cm³, in-line 4-cylinder, liquid cooled and with Ram Air engine, which is capable of generating up to 59 kW (80 hp) of maximum power (when the Ram Air is pressurized). According to the brand, this engine is capable of revving up to 15,000 rpm.

In addition, in all versions, the front suspension is an USD Showa SFF-BP (Separate Function Fork – Big Piston), with a preload adjustment mechanism on the ZX-4R SE and ZX-4RR, and the brake system has with dual 290mm semi-floating front discs and radial-mount monobloc calipers.

Finally, technology is not lacking in the new bike. It brings, as standard, assist and slipper clutch, ECO indicator, electronic throttle body, KQS (Kawasaki Quick Shifter), KTRC (Kawasaki Traction Control), Power modes, ABS brakes, Horizontal Back-Link rear suspension, Full-LED Lighting, 4.3″ color TFT digital panel and Smartphone connection.

Anyway, the 2024 Kawasaki Ninja ZX-4R is expected to hit stores in Europe and North America in the fall of 2023. Pricing has not yet been announced.
