Kawasaki Z650 2020

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.
