The Kawasaki Ninja 400 is a 399 cc Ninja series sport bike introduced by Kawasaki in 2018, as a successor to the Ninja 300. It launched with the 2018 model year.

The Ninja 300 was struggling through Euro 4 emission standards compliance. Therefore, Kawasaki decided to replace it with the Ninja 400 for the 2018 model year. It also has significant upgrades in engine, frame, suspension, and other parts.
