Next-level Power

The Ninja 400 engine delivers the perfect balance of high-performance thrills and easy-to-use power.

Class-leading Power

The four-stroke, 399 cc Parallel -Twin is the largest displacement engine in its class and delivers smooth easy-to-use power for maximum rider confidence while also offering outstanding fuel efficiency.

Assist & Slipper Technology

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.

Lightweight & Agile

Similar in design to the unprecedented Ninja H2 hypersport bike, the tube-type trellis frame is light in weight for smooth control and handling.

Progressive & dependable

The class-leading semi-floating front disc brake delivers strong, progressive braking performance and is complemented by an Anti-lock Brake System (ABS) that helps reduce wheel lock-up under certain conditions.

Designed for Comfort

A sporty yet relaxed riding position accommodates a wide variety of riders and riding situations.

Sporty & Comfortable

Clip-on style handlebars offer a raised position for added comfort.

Easy & Accessible

A narrow seat design and low 785 mm seat height allows the rider to confidently reach the ground and creates a lower center of gravity for confident handling.

Added Comfort

Forward-oriented footpeg position contributes to comfortable ergonomics and a confident reach to the ground at stops.

Sharp & Modern

Aggressive Ninja styling boasts high-class modern design with superb fit and finish inspired by the larger displacement Ninja supersport bikes.
