Kawasaki Ninja 400 weight FAQ
What does the Kawasaki Ninja 400 weigh ready to ride?

Is the Kawasaki Ninja 400 heavy compared with other Kawasaki sport bikes?
It sits fairly close to the middle of the category. Its representative wet weight is around the 54th percentile among 86 compatible Kawasaki sport bikes.
Does the Kawasaki Ninja 400 weight change by model year?
Not every covered year uses the same figure. The page groups identical values together and lists the later model years where the supplied weight specification changes.
How much does the Kawasaki Ninja 400 fuel weigh?
The listed tank capacity is 0.98 US gal (3.7 L) to 4.09 US gal (15.5 L). Using approximately 0.745 kg/L gasoline, a full tank is roughly 6.1 lb (2.8 kg) to 25.5 lb (11.5 kg). That is an estimate for fuel mass, not an official Kawasaki curb-weight calculation.
How heavy is the Kawasaki Ninja 400 with an average-size rider?
A 180 lb rider brings the simple bike-plus-rider total to roughly 640.8 lb (290.6 kg) using the representative wet/running figure. Gear and luggage would add more.

Using the listed dry weight plus the calculated fuel mass, the estimated weight with a full tank is 367.6 lb (166.8 kg) to 374.2 lb (169.8 kg). That still may not equal official curb weight because dry-weight definitions can exclude other fluids or equipment.
