This makes it an excellent choice for daily commuting or long rides where fuel stops may be infrequent.

In terms of maintenance, the Ninja 400 follows Kawasaki’s reputation for reliability. Regular servicing and maintenance, including oil changes and chain adjustments, will ensure that the bike remains in top condition. The availability of genuine Kawasaki parts and a widespread service network further adds to the convenience of owning a Ninja 400.
