The Kawasaki Z650 RS 2022 and the Kawasaki Z900 2021 are both naked bikes from Kawasaki, but they have some key differences in terms of specifications and features.

Starting with the engine and powertrain, the Kawasaki Z650 RS 2022 is equipped with an inline twin-cylinder engine that produces 68.2 HP of power and 65.7 Nm of torque. On the other hand, the Kawasaki Z900 2021 features a more powerful inline four-cylinder engine that generates 125.4 HP of power and 98.6 Nm of torque. This makes the Z900 significantly more powerful than the Z650 RS.

In terms of fueling, both bikes come with fuel injection systems. However, the Z650 RS has a displacement of 649cc, while the Z900 has a larger displacement of 948cc. This larger displacement contributes to the higher power output of the Z900.

Moving on to the suspension, both bikes have a telescopic fork at the front and a monoshock at the rear. However, the Z900's front suspension is an inverted telescopic fork, which is considered to be more advanced and provides better performance compared to the standard telescopic fork on the Z650 RS. Additionally, the Z900's rear suspension offers adjustment options for preload and recovery, allowing riders to fine-tune the suspension according to their preferences.

On the other hand, the Z900 is praised for its powerful four-cylinder engine, intuitive handling, good equipment, aggressive appearance, and good value for money.

As for weaknesses, the Z650 RS has a slightly smoother sound compared to the Z900. On the other hand, the Z900 lacks the option for quick gear shifting and some competitors offer electronic 6-axis IMU technology, which provides advanced riding aids.

Overall, the Kawasaki Z650 RS 2022 and the Kawasaki Z900 2021 are both impressive naked bikes with their own unique strengths and weaknesses. The Z900 offers more power and advanced features, while the Z650 RS provides a more retro-inspired design and a more accessible riding experience. Ultimately, the choice between the two will depend on the rider's preferences and priorities.
