Kawasaki Z900 2021

In terms of price-performance, the Kawasaki Z900 is hard to beat at the moment. With the perfectly tuned engine, the high-quality chassis components and the electronics added for 2020, this naked bike offers everything that sporty riders will be looking for. There is really nothing to complain about, except for the lack of a quickshifter option.

Kawasaki Z650 2020

It's simply marvellous what Kawasaki has put together in a complete package with the new Z650. The technical components may not knock your socks off individually, but in combination they make for a pleasantly neutral motorbike that everyone will enjoy. No bitchy idiosyncrasies - simply a naked bike that works really well on winding country roads. Of course, the TFT display, which we don't find in the competition at the moment, is a plus, as is the grown-up look, which is strongly oriented towards the larger Z models. Only the pressure point of the front brake could have been more clearly defined - but you can't have everything in this price range.
