The Kawasaki Z650 2017 and the Aprilia Tuono 660 2021 are both naked bikes with similar engine configurations and displacement. However, there are several differences between the two models.

In terms of engine power, the Aprilia Tuono 660 2021 has a clear advantage with 95 HP compared to the Kawasaki Z650 2017's 68.2 HP. This means that the Tuono 660 offers more power and potentially better acceleration.

Both bikes have a similar torque output, with the Kawasaki Z650 2017 producing 65.7 Nm and the Aprilia Tuono 660 2021 producing 67 Nm. This means that both bikes should offer good low-end and mid-range torque for a responsive riding experience.

The chassis construction is also different between the two models. The Kawasaki Z650 2017 has a steel frame, while the Aprilia Tuono 660 2021 features an aluminum frame. Aluminum frames are generally lighter and offer better handling characteristics, so the Tuono 660 may have an advantage in terms of agility and maneuverability.

In terms of braking, both bikes have double disk brakes at the front. However, the Aprilia Tuono 660 2021 has larger diameter disks (320 mm) and four-piston calipers, which should provide better stopping power and more precise braking compared to the Kawasaki Z650 2017's double piston calipers and 300 mm disks.

When it comes to rider assistance systems, the Aprilia Tuono 660 2021 offers a more extensive range of features.

In terms of weaknesses, the Kawasaki Z650 2017 is mentioned to be a little too small for tall people. The Aprilia Tuono 660 2021, on the other hand, is criticized for its price-performance ratio not being right and some of its electronic features requiring additional costs.

Overall, the Aprilia Tuono 660 2021 seems to offer more advanced features, better performance, and a sportier riding experience compared to the Kawasaki Z650 2017. However, it is important to consider personal preferences, budget, and intended use when choosing between the two models.

Pros and Cons in comparison

Kawasaki Z650 2017

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!

The Tuono delivers on the bends what the name promises. The sporty naked bike rides precisely and you enjoy the sporty corner chase. At the exit of the bend, however, one wishes for more emotion and adrenaline. The sporty expectation is naturally also created by the Tuono's racy appearance and cheeky demeanour. But this expectation is unfortunately not quite fulfilled in the saddle.
