Pros and Cons in comparison

Kawasaki Z900 2017

Kawasaki Z900 2017

An incredibly well-designed motorbike. A lot of test work and attention to detail went into it. It has exactly the right power, exactly the right chassis and exactly the right look. An all-round successful naked bike that will make you happy for a long time. If you like, you can ride it simply and faithfully, but if you want, you can also ride it really fast and it wheels like hell. Great!

Ingenious nakedbike chassis

superb looks

engine responds super fine, revs up willingly and has a perfectly dimensioned torque

optimum intersection of performance, price and practical use

Knee angle very narrow for tall people (order another seat!)

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.
