A fiercely authentic supernaked, the Kawasaki Z400 exudes fresh street style and is immediately recognisable in a crowd with its compact chassis and aggressive styling. Comfortable, balanced and capable, the Z400 offers a visceral riding experience that’s sure to turn heads.

Predatory Instinct

A fierce, lightweight supernaked built for the streets.

Legendary Sport Performance

Exciting power, smooth response and abundant low-end torque is produced by the same class-leading Parallel Twin engine as the Ninja 400 sportbike.

Assist & Slipper

A compact clutch assists with a light feel at the lever and a wide engagement range for confident control. A back-torque limiting slipper function helps prevent rear-wheel hop when downshifting.

All Eyes on You

Taking cues from its Z brethren, the unmistakable streetfighter styling complements an aggressive attitude.

Aggressive & Agile

Edgy, minimalist bodywork is influenced by Sugomi, a design that inspires sharp styling, dynamic performance and a distinct silhouette.

Sporty Design

The angular design of the front cowl is complemented by a compact, dark meter visor that adds to the aggressive looks.

Modern LED Headlight, Taillight & Brake Light

Quad LED headlamp is highly visible and offers significant brightness and a wide illuminated path.

Exposed Trellis Frame

Similar in design to that of the Ninja H2, the trellis frame design adds to the technical and lightweight image in distinct supernaked style while delivering a balanced riding experience for light and easy manoeuvring with excellent capability at highway speeds.

High-grade & Modern

Stacked instrument cluster features a clean and easy-to-read analogue-style tachometer and multi-function LCD screen with gear position indicator fuel and temp gauges, economical riding indicator and more.

Agile & Precise

The Z400 motorcycle was built to deliver light, predictable and natural handling for a confident riding experience.

Sporty & Stylish

Stylish star-pattern 5-spoke wheels contribute to the Z400’s light weight and feature optimised lateral rigidity that benefits cornering and overall handling.

Fully Adjustable

5-way preload adjustability lets riders adjust the stiffness and ride height to suit body weight or when riding two-up.

Refined & Responsive

Plush suspension comes thanks to a o41 mm telescopic front fork that’s tuned to provide progressive damping with a high level of feedback to the rider and responsive performance.

Superb Stopping Power

Gripped by a balanced actuation dual-piston caliper, the Z400 boasts a large o310 mm semi-floating petal front disc. Nissin’s ABS control unit is compact and lightweight, delivering precise control to help prevent wheel lockup under extreme braking.

Comfort in Every Detail

The upright riding position, low seat height and wide handlebar put the rider in the ideal position for active control, facilitating dynamic, sporty riding.

Comfortable & Sporty

Sporty aluminium footpegs offer direct feel and are positioned slightly forward, offering a comfortable riding position and clear reach to the ground at stops.

Balanced & Wide

The wide handlebar adds leverage for dynamic control and contributes to easy manoeuvrability.
