Kawasaki is preparing to launch an exciting new motorcycle that channels the spirit of the 1990s, marking the return of the four-cylinder 400cc sportsbike. The new Ninja ZX-4R, set for release in the autumn of 2023, is a long-awaited model that revives the performance and thrill of the iconic ZXR400, which was last seen nearly 30 years ago. With its sleek design, high-revving engine, and modern features, the ZX-4R promises to be a standout in the sportsbike market.
Powerful 399cc Four-Cylinder Engine
At the heart of the Kawasaki Ninja ZX-4R is a 399cc DOHC (Double Overhead Cam) four-cylinder engine that is capable of producing an impressive 78.9bhp. This high-revving engine can push beyond 15,000rpm, offering a thrilling riding experience for those who love to experience high speeds. The engine’s power delivery is aided by a ram-air system that boosts performance, especially at high revs.
Despite the compact size, the ZX-4R’s engine provides strong low and mid-range torque, making it an ideal bike for spirited riding. The motor is designed to deliver a balance of power across different rpm ranges, but for peak performance, riders will need to push the engine to its limits. This emphasis on revving and performance makes the ZX-4R a bike built for those who enjoy pushing their machines to the edge.
High-Quality Chassis and Suspension
The frame of the ZX-4R is constructed from high-tensile steel, providing an excellent mix of rigidity and flexibility. This construction contributes to the bike’s nimble handling and agility, making it a pleasure to ride both on track and on regular roads. The chassis design is borrowed from the smaller ZX-25R, ensuring that the ZX-4R retains the lightweight and responsive nature of its smaller sibling.
To further enhance its handling capabilities, the ZX-4R is equipped with Showa suspension components, including upside-down separate function big-piston forks at the front and a mono-shock at the rear. These high-performance suspension parts are inspired by those found on Kawasaki’s flagship Ninja ZX-10R, ensuring that the ZX-4R delivers a smooth, stable ride while maintaining excellent cornering ability. The suspension setup is designed to offer riders a comfortable yet sporty ride experience, whether on twisty roads or during track days.
Enhanced Braking and Tyres
When it comes to stopping power, the ZX-4R does not disappoint. The bike is equipped with dual 290mm semi-floating front discs and radially mounted calipers. This setup ensures strong and consistent braking performance, giving riders the confidence to push the limits of the bike while remaining in control. The ZX-4R also comes with 120/70×17 front tyres and 160/60×17 rear tyres, providing plenty of options for high-quality, grippy rubber, which is essential for achieving optimal performance on both wet and dry surfaces.
Models and Features
Kawasaki will offer the ZX-4R in three versions: the standard ZX-4R, the ZX-4R SE, and the ZX-4R RR. Each model has slightly different features, catering to various rider preferences.
- ZX-4R SE: This version includes a Kawasaki Racing Team (KRT) paint job, an up/down quickshifter, a smoked screen, a USB power socket, and frame sliders. It’s an exciting option for those who want a more track-ready bike with a touch of racing style.
- ZX-4R RR: This variant features the same quickshifter and blipper function as the SE, as well as RR graphics, Showa’s BFRC-lite shock, and pre-load adjustable front forks. These additional components further improve the bike’s handling and performance, making it an excellent choice for riders looking for the ultimate ZX-4R experience.
All models also include modern electronics, such as traction control, four different riding modes, and a 4.3-inch LCD display with mobile connectivity. The full LED lighting adds a modern touch to the bike, making it stand out in both appearance and functionality.
Design and Styling
The design of the ZX-4R draws inspiration from Kawasaki’s larger Ninja models, especially the Ninja ZX-10R. It incorporates styling elements such as sharp, angular lines and aggressive looks that are typical of Kawasaki’s sportier bikes. The ZX-4R also features a sleek banana-style swingarm, a component seen on the Ninja 650. The curved rear swingarm enhances the bike’s overall visual appeal while maintaining its lightweight structure.

Additionally, Kawasaki has gone a step further by designing the ZX-4R with enhanced aerodynamics. The lower panels of the bike are specially designed to improve airflow, directing air to crucial components like the alternator and clutch. This cooling system design, borrowed from the ZX-25R, helps maintain optimal engine performance even under demanding riding conditions.
A Global Appeal
The ZX-4R’s primary target market is expected to be Asia, where smaller displacement sportsbikes are in high demand. However, with its larger engine capacity and increased performance, Kawasaki might expand its availability to Western markets, making it an attractive option for riders around the world.
The ZX-4R is designed to offer a perfect blend of everyday usability and thrilling performance. Its engine is powerful yet manageable, and its handling and suspension setup are ideal for both daily commutes and weekend track days. Whether you’re a fan of light, high-revving motorcycles or looking for an entry-level sportsbike with the performance of a big bike, the ZX-4R offers an excellent balance of both worlds.
Conclusion
Kawasaki’s Ninja ZX-4R is an exciting addition to the sportsbike scene, combining a high-revving four-cylinder engine with cutting-edge suspension and braking technology. Its lightweight, agile frame and powerful engine make it a thrilling ride, while the bike’s modern features and stylish design ensure it stands out from the crowd. With three different versions catering to various rider needs, the ZX-4R is set to make waves in the world of sportbikes, particularly for those looking to experience the fun and excitement of a 400cc four-cylinder machine. The ZX-4R may be a modern interpretation of Kawasaki’s legendary ZXR400, but it’s poised to become a new classic in its own right.
