Kawasaki Ninja 400 KRT weight overview
This is neither unusually light nor extremely heavy. For most riders the practical weight question is more about seat height, center of mass and low-speed balance than the scale number alone. The comparison uses dry weight because a usable wet/running figure was not supplied, so the actual ready-to-ride motorcycle will be heavier.

Kawasaki Ninja 400 KRT weight FAQ
How heavy is the Kawasaki Ninja 400 KRT?
