The Kawasaki Z900 model year 2017 and the Kawasaki Z650 model year 2021 are both naked bikes from Kawasaki, but they have some notable differences in terms of specifications and strengths.

Starting with the engine and drive train, the Kawasaki Z900 2017 is equipped with an in-line, 4-cylinder engine that produces 125.4 HP of power and 98.6 Nm of torque. On the other hand, the Kawasaki Z650 2021 features an in-line, 2-cylinder engine that generates 68.2 HP of power and 65.7 Nm of torque. The Z900 has a larger displacement of 948cc compared to the Z650's 649cc. This means that the Z900 offers more power and torque, making it a more high-performance option.

In terms of suspension, both bikes have a swing arm rear suspension with a monoshock absorber.
