Finding the right balance between displacement, affordability and performance is a tough game to play but with the 2018 Ninja 400, Kawasaki may have just rolled the dice right. Don’t be fooled because even though the Ninja 400 has the same aesthetic as the rest of the Ninja family, Kawasaki completely went all out with this one. First, they bumped the engine displacement to 399 cc, nearly a 35 percent increase from its predecessor the Ninja 300.  The engine has new bore and stroke measurements, an updated intake and exhaust system, lighter forged cams, a lighter and smaller slip/assist clutch, higher compression ratio, and many other tech updates.

Even though it packs more power, can you believe that the Ninja 400 is also 17 pounds lighter than the 300 it replaces? Yes, you read that right. The bodywork also saw a major improvement as it now has an uncanny resemblance to the beauty that is the Kawasaki Ninja H2,  Kawasaki’s “supercharged supersport” class motorcycle in the Ninja sportbike series.

The Ninja 400 also received new brakes, suspension, chassis, rider geometry, wheels and bodywork, making this a ground-up new model for 2018. It may strike as a thoroughbred supersport at first glance, but Kawasaki made sure that it is still practical and approachable from an ergonomic standpoint. With a narrow seat design and low 30.9″ seat height for confident reach to the ground and lower center of gravity, the Ninja 400 couldn’t get more comfortable making it super ideal for everyday commute, and perfect even for riders who are just getting started.
