Kawasaki Ninja 400 Performance 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 Performance weight FAQ
How heavy is the Kawasaki Ninja 400 Performance?
Listed dry weight is 370.4 lb (168 kg). Because no usable wet/running figure was supplied, treat that as a lower starting point rather than the exact on-road weight.

It sits fairly close to the middle of the category. Its representative dry weight is around the 48th percentile among 21 compatible Kawasaki sport bikes.
How much does the Kawasaki Ninja 400 Performance fuel weigh?
The listed tank capacity is 3.7 US gal (14 L). Using approximately 0.745 kg/L gasoline, a full tank is roughly 23 lb (10.4 kg). That is an estimate for fuel mass, not an official Kawasaki curb-weight calculation.
How heavy is the Kawasaki Ninja 400 Performance with an average-size rider?

Can I treat the Kawasaki Ninja 400 Performance dry weight as curb weight?
No. The usable figure is dry weight, so it excludes at least some operating fluids. Dry weight plus the estimated full fuel load is about 393.4 lb (178.4 kg), and oil/coolant or definition differences may add more.
What does the Kawasaki Ninja 400 Performance weigh with a full tank?
Based on the available dry-weight and tank-capacity data, a full-tank estimate is 393.4 lb (178.4 kg). Oil, coolant and market-specific equipment can still make actual ready-to-ride weight different.
How much torque does the Kawasaki Ninja 400 Performance have per 100 lb?
The calculated torque-to-weight range is 7.37 lb-ft per 100 lb. It is useful for comparing bikes with very different overall weights.
What is the Kawasaki Ninja 400 Performance displacement per pound?
Engine displacement relative to bike weight is 1.08 cc per lb. It can help compare motorcycles from very different displacement classes without relying on cc alone.
Will the Kawasaki Ninja 400 Performance feel heavy at low speed?
It is most likely to feel heavy while stopped, backing up or on a slope rather than once settled at normal riding speed. Seat height and center of gravity matter a lot.
Motorcycle specifications can vary by model year, market, equipment and the exact dry/curb-weight definition.
