Kawasaki proudly introduces a new sport model into this highly competitive arena. Clad in sharp new Ninja styling, the new Ninja 400 delivers greater performance than its predecessor care of all new engine and chassis that are more powerful and significantly lighter. But like the Ninja 300 that preceded it, this new Ninja model possesses much more than high performance. The new model takes the winning formula that drove the success of the Ninja 250R and its successors, and amplifies it. Not only does the Ninja 400 offer stunning, high-quality looks, its stronger engine performance, light, predictable handling and relaxed, sporty riding position make it both fun and easy to ride. This duality – the ability to offer excitement and ease of riding to wide range of customers – is sure to make the new Ninja 400 a fan favourite once again.
The Ninja 400 all-new 399 cm³ engine delivers a balance of performance and controllability. The new engine offers increased performance at all rpm compared to its predecessor, with good power feeling. Smooth, predictable response contributes to an easy-to-control engine character. Thanks to its efficient design, the compact, lightweight engine has a size on par with 250cc engines.
Large 310 mm semi-floating petal front disc (effective diameter: ø286 mm) is gripped by a balanced actuation dual-piston caliper. The disc – the largest in its class – is the same size as the ones used on the Ninja ZX-14R
Simplified exhaust system traces a straighter line, contributing to lower weight. Pipe wall thickness of 0.8 mm further contributes to weight savings. The exhaust design features 28.6 mm diameter headers with a connecting pipe enhancing the mid range torque. The stylish muffler provides a high grade appearance.
Radial tyres on the Ninja 400 offer light weight, excellent grip and contribute to both agile handling and riding comfort. Further, the 150 mm rear tyre adds to a more imposing looking rear end.
In addition to contributing to the Ninja 400’s sharper looks, slim dual LED headlamps (each featuring low and high beams, as well as a LED position lamp) are highly visible and offer significantly increased brightness. Chin spoilers at the bottom of the front cowl were inspired by the Ninja H2 and Ninja ZX-10R.
Supersport style downdraft intake provides a shorter, more direct path for intake air to enter the cylinder, improving cylinder filling efficiency and contributing to increased engine power, especially at high rpm. (The downdraft intake also contributes to chassis layout by freeing up space under the seat, facilitating a design that offers an easy reach to the ground.
More compact Assist & Slipper Clutch (ø139 mm >> ø125 mm) with less rigid operating plates offers a 20% lighter lever pull. Complementing the extremely light feel at the lever, the new clutch has a wider engagement range, facilitating control.
A more rigid 41 mm telescopic fork (previously ø37 mm) delivers better suspension action. The front wheel feels really planted, direction changes are made easily (even when the bike is fairly upright – handy when navigating traffic jams), and overall the suspension offers the plushness of a larger model.
