Features

Ergonomics

  • 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 30.9” 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.

Handling

  • NIMBLE & AGILE: The Ninja® 400 motorcycle’s chassis dimensions were designed to deliver confident handling with a modern sporty feel at all speeds.
  • 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. (*Model available in ABS and Non-ABS)

Power

  • NEXT-LEVEL POWER: The Ninja® 400 motorcycle engine delivers the perfect balance of high-performance thrills and easy-to-use power.
  • CLASS-LEADING POWER: The four-stroke, 399cc twin-cylinder 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.
  • CONFIDENT ACCELERATION: Best in class roll-on acceleration to confidently accelerate up to speed.

Styling

  • SHARP & MODERN: Aggressive Ninja® styling boasts high-class modern design with superb fit and finish inspired by the larger displacement Ninja supersport bikes.
  • HIGH-TECH: The high-grade cockpit of the Ninja® 400 motorcycle features a multi-function dash meter that includes a gear position indicator.
  • EXCELLENT VISIBILITY: Twin LED headlights produce strong white lighting and include low and high beams as well as position lamps.
