Overview - Kawasaki Z900 2019 vs Kawasaki Z650 2021

The Kawasaki Z900 2019 and the Kawasaki Z650 2021 are both naked bikes from Kawasaki, but they have some key differences in terms of specifications and strengths.

Starting with the engine, the Kawasaki Z900 2019 is equipped with a more powerful engine compared to the Kawasaki Z650 2021. The Z900 has an inline 4-cylinder engine with a displacement of 948cc, producing 125.4 horsepower and 98.6 Nm of torque. On the other hand, the Z650 has a smaller inline 2-cylinder engine with a displacement of 649cc, producing 68.2 horsepower and 65.7 Nm of torque. This means that the Z900 offers more power and torque, providing a more exhilarating riding experience.

In terms of suspension, both bikes have a swing arm rear suspension with a monoshock absorber. However, the Z900 offers more adjustability with preload and rebound adjustments, while the Z650 only has preload adjustment. This allows riders to fine-tune the suspension settings according to their preferences and riding conditions.

Both bikes have a steel frame, but the Z900 has a double cradle frame while the Z650 has a tubular frame. The double cradle frame of the Z900 provides better stability and handling, contributing to a more confident riding experience.

In terms of dimensions and weights, the Z900 has a slightly larger wheelbase of 1450mm compared to the Z650's 1410mm. The Z900 also has a higher seat height of 795mm compared to the Z650's 790mm.

On the other hand, the Z650 2021 has its own strengths. It features an accessible two-cylinder engine that is suitable for riders who prefer a more manageable power delivery. The compact dimensions and low seat height make it easier to handle, especially for shorter riders. The chassis provides stability and confidence, allowing riders to feel in control. The Z650 also comes with a TFT display with connectivity, offering modern features and convenience. Lastly, the Z650 has a grown-up look, appealing to riders who prefer a more mature aesthetic.

However, both bikes have their weaknesses as well. The Z900's TFT display is mounted too low, which can be inconvenient for riders as they have to take their eyes off the road to view it. The menu operation can also be cumbersome. The rearview mirrors on the Z900 offer modest visibility, which can be a drawback in terms of safety.

On the other hand, the Z650 may not be as comfortable for tall riders due to its low seat height. Additionally, some riders may find the adrenaline level in the saddle to be lower compared to the competition, indicating that it may not provide the same level of excitement and thrill.

In conclusion, the Kawasaki Z900 2019 and the Kawasaki Z650 2021 are both capable naked bikes with their own strengths and weaknesses. The Z900 offers more power, adjustability, and stability, while the Z650 provides accessibility, compactness, and a modern look.
