Overview - Kawasaki Z900 2023 vs Kawasaki Z650 2017

The Kawasaki Z900 model year 2023 and the Kawasaki Z650 model year 2017 are both naked bikes from Kawasaki, but they have several differences in terms of their technical specifications and strengths.

Starting with the technical specifications, the Kawasaki Z900 2023 is equipped with a more powerful engine compared to the Kawasaki Z650 2017. The Z900 has an in-line, 4-cylinder engine with a displacement of 948cc, producing 125 horsepower and 98.6 Nm of torque. On the other hand, the Z650 has an in-line, 2-cylinder engine with a displacement of 649cc, generating 68.2 horsepower and 65.7 Nm of torque. This means that the Z900 offers significantly 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 has an upside-down telescopic fork front suspension, while the Z650 has a regular telescopic fork front suspension. The upside-down telescopic fork on the Z900 provides better stability and control during aggressive riding, making it more suitable for sportier riding styles.

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 on the Z900 offers better rigidity and stability, enhancing the bike's overall handling and performance.

When it comes to advanced rider assistance systems, the Z900 2023 offers more features compared to the Z650 2017. The Z900 comes with ABS, riding modes, ride by wire, and traction control, while the Z650 only has ABS.

Additionally, the Z900 is heavier with a kerb weight of 212kg (with ABS), while the Z650 weighs 187.1kg (with ABS).

Moving on to the strengths of each bike, the Kawasaki Z900 2023 offers light and natural handling with high stability. It has a silky engine that delivers full pull from low revs, providing a smooth and powerful riding experience. The Z900 also has a high chassis transparency, offering great feedback to the rider.

Pros and Cons in comparison

Kawasaki Z900 2023

Kawasaki Z900 2023

The Kawasaki Z900 may not be up to scratch when it comes to modern, lean angle-dependent electronic features, but it's relatively cheap and you shouldn't underestimate the fan base of the good old inline four - the Z900 is one of the cheapest ways to own such a great engine with just under a litre of displacement in a sporty naked bike! The higher weight is noticeable, but not massively annoying, because the handling and stability are quite alright. In terms of "outdated" electronics, the most annoying thing is the missing shift assistant, which is not even available as an option. Overall, however, the Z900 is a great naked bike with a great price-performance ratio.

Kawasaki Z650 2017

The Kawasaki Z 650 is the tip of the middle class for small male and female riders. On its compact dimensions, you probably won't feel comfortable as a giant. Heart-warming feelings, however, come from the engine, which delights with a very smooth pull. On the chassis side, a Kawasaki-typical tight set-up was chosen, which finds a great compromise in everyday use. The negative display is very easy to read and is reminiscent of its predecessor, the ER-6n - very nice!
