Kawasaki Ninja ZX-4RR 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 ZX-4RR KRT weight FAQ
How heavy is the Kawasaki Ninja ZX-4RR KRT?
Listed dry weight is 366 lb (166 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 36th percentile among 81 compatible Kawasaki motorcycles.
How much does the Kawasaki Ninja ZX-4RR KRT fuel weigh?
The listed tank capacity is 4 US gal (15.14 L). Using approximately 0.745 kg/L gasoline, a full tank is roughly 24.9 lb (11.3 kg). That is an estimate for fuel mass, not an official Kawasaki curb-weight calculation.

What is the Kawasaki Ninja ZX-4RR KRT full-tank weight estimate?
Using the listed dry weight plus the calculated fuel mass, the estimated weight with a full tank is 390.8 lb (177.3 kg). That still may not equal official curb weight because dry-weight definitions can exclude other fluids or equipment.

Motorcycle specifications can vary by model year, market, equipment and the exact dry/curb-weight definition.
