Pros and Cons in comparison

Pros and Cons in comparison

Kawasaki Z900 2018

Kawasaki Z900 2018

In the hotly contested naked bike segment, the Z900 plays right at the front. Above all, its engine is absolutely terrific, runs incredibly silky and offers rich power in all rev regions - as befits a Japanese four-cylinder. Its sporty, aggressive appearance matches this. It does without electronic bells and whistles, but still conveys a lot of confidence when chasing corners, braking and accelerating out of them. The low seat is especially beneficial for smaller riders, but taller riders might miss a flatter knee angle on long distances. The low weight and compactness make the Z900 particularly agile and easy to handle. A sporting cannon that is also extremely appealing in terms of price

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.
