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!
