2020 Kawasaki Ninja 400

What started out in 34 years ago as a 250-class machine with limited freeway capabilities has blossomed into a 400-class motorcycle ready for the track and freeway commuting.

In spite of its small displacement, the 2020 Kawasaki Ninja 400 is a versatile motorcycle that can satisfy a wide number of demands.

Kawasaki Ninja 400 2020 seat heightAs a commuter, the 2020 Ninja 400 is stable on the freeway, with power to spare and a top speed over 100 mph. At the same time, weighing in at just 362 pounds with its 3.7-gallon fuel tank topped off, the Ninja 400 is agile in urban traffic and easy to handle.

The assist and slip clutch helps keep your commute from being arduous, as does the upright seating position behind the angular fairing. If you’re concerned the Ninja 400’s ergonomics might be too tight, an optional Kawasaki seat expands the seat/grip/pegs triangle.

If you have canyons nearby, the 2020 Kawasaki Ninja 400 is a formidable motorcycle on tight canyon roads. The peppy DOHC parallel-twin motor, scrappy Dunlop Sportmax GPR-300 radial tires, 310mm front disc brake, and well thought out non-adjustable suspension units work nicely in concert for optimal performance.
