Two of Kawasaki’s stand-out A2 licence compliant machines of recent years make a welcome return for the 2023 model year line up.

As the naked style category continues to expand in size and popularity, the Z400 will ably fulfil the need for a Z model for A2 licence holders fashioned in the same style as its Sugomi styled Z siblings. 2022 has witnessed celebrations highlighting 50 years of the famous Z range providing a springboard for the re-introduction of the Euro5 compliant Z400 complete with its 399 cm3 parallel twin water-cooled engine delivering 33.4 kW (45PS) and 37 N.m (3.8kg-m) of torque at 8,000 rpm.

Complete with an assist and slipper clutch and a trellis frame mirroring the chassis of the range-leading Z H2, the Z400 provides a big bike personality in a manageable package for those making their way up the capacity ladder or those who feel the 400cc class is their ideal destination.

A seat height of 785 mm contributes towards admirable manoeuvrability while Kawasaki’s unique ERGO-fit optional seat enhances riding comfort for taller riders, making the Z400 the most logical choice in class.

Track focused fans also have good reason to rejoice in 2023 as the range partner for the Z model will be the highly popular Ninja 400. The base machine for race and Championship winning machinery in the highly competitive WorldSSP300 Championship, the handling and performance credentials of the Ninja need no further amplification. The chosen mount of current champion, Adrian Huertas, the new 2023 Ninja 400 shares its A2 licence compliance with the Z400 along with a tubular trellis chassis and powerful 286mm front disc brake coupled with an equally effective 193mm rear rotor.

Ninja style never goes out of fashion and the Ninja 400 revels in its family resemblance to the mighty Ninja ZX-10R, a machine that has achieved unparalleled levels of WorldSBK Championship success. And like its Ninja big brother, the 400-class machine also features an assist and slipper clutch facilitating smooth gear down changes and a 20% lighter lever pull at the handlebar.

Anticipation for the re-introduction of not one but two A2 licence compliant 400cc class machines in Euro5 specification will build towards their addition to a comprehensive range for the 2023 model year creating a tough yet enjoyable choice for prospective owners. Naked style or Ninja style, Kawasaki has the 2023 mid-capacity class bases covered.

In addition to contributing to the Ninja 400’s sharper looks, slim LED headlamps (each featuring low and high beams, as well as a LED position lamp) are highly visible and offer significantly increased brightness.

Relaxed rider triangle accommodates a wide range of rider sizes and riding situations. Compared to some other models (whose somewhat extreme riding position compromises comfort), the elevated handle position and slightly foot-forward footpeg position put the rider in a position to control the bike while also offering rider comfort.

The Ninja 400’s 399 cm3 engine delivers a balance of performance and controllability. The 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.

While seat height is 785 mm, the slim design of both the seat and the rear of the engine gives riders an unobstructed line for their feet to reach the ground.

The Ninja 400 is equipped with a sophisticated cockpit, featuring a large analogue tachometer flanked by warning lamps on one side, and a gear position indicator and multi-function LCD screen on the other.

Head-turning looks have always been a forte of Ninja models, regardless of displacement. The new Ninja 400 boasts futuristic new Ninja styling inspired by the mighty Ninja H2. The largevolume bodywork attracts attention, and gives the impression of a larger machine. This impression is reinforced by the high-class design and superb fit and finish, which are comparable to bikes from a larger-displacement class.

Measuring ø310 mm (the same disc size used on the Ninja ZZR1400), the Ninja 400's semifloating front disc offers sure stopping power. A rigid new front brake master cylinder helps eliminate ineffective (idle) stroke, contributing to controllability, while carefully selected brake hose dimensions and material contribute to brake touch. Featuring the latest ABS unit from Nissin, the most compact and lightweight available.

The Ninja 400 features a trellis frame similar in design to that of the Ninja H2. Kawasaki’s advanced dynamic rigidity analysis was used to ensure optimum rigidity with light weight. The engine is rigidmounted and used as a stressed member. The frame design contributes significantly to the bike’s low curb mass.
