2023 Ninja 400 - Special

The Ninja 400's 399 cc engine delivers a balance of performance and controllability. Strong performance at all rpm is complemented by good power feeling. Smooth, predictable response contributes to an easy-to-control engine character.

The engine's strong performance can largely be credited to its downdraft intake, which is accompanied by a large airbox that contributes to intake efficiency. The performance is complemented by a rider-friendly character; the smooth response and abundant low-end torque facilitate throttle control for new and experienced riders alike.

Developed based on feedback from racing activities, the Assist & Slipper Clutch uses two types of cams (an assist cam and a slipper cam) not available on a standard clutch. The assist function provides an exceptionally light clutch pull and produces a wide clutch engagement range for comfort and confidence. The slipper function reduces the effect of back-torque for smooth and seamless downshifts.

Innovative Kawasaki technology like the patented radiator fan cover located behind the radiator directs hot air out to the sides away from the rider, contributing to rider comfort.

With its light weight, the chassis delivers a balance of stability and light, easy manoeuvrability. Its slim design facilitates both control and ease of riding, making the Ninja 400 an easy choice for both new and experienced riders

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 rigid-mounted and used as a stressed member. The frame design contributes significantly to the bike's low curb mass.

Rigid ø41 mm telescopic fork delivers excellent 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 displacement bike. At the rear, 5-way preload adjustability lets riders adjust the stiffness and ride height to suit body weight or when riding two-up.

Measuring ø310 mm, the Ninja 400's semi-floating front disc offers sure stopping power. A rigid front brake master cylinder helps eliminate ineffective (idle) stroke, contributing to controllability, while carefully selected brake hose dimensions and material contribute to brake touch.

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.

Head-turning looks have always been a forte of Ninja models, regardless of displacement. The Ninja 400 boasts futuristic Ninja styling inspired by the mighty Ninja H2. The large-volume 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.

In addition to contributing to the Ninja 400's sharp looks, slim LED headlamps (each featuring low and high beams, as well as a LED position lamp) are highly visible and offer significant brightness

The Ninja 400's sophisticated instrument cluster contributes to the high-grade feel of the tidy cockpit. The instrumentation features a large analogue tachometer flanked by warning lamps on one side, and a gear position indicator and multi-function LCD screen on the other.
