Kawasaki Ninja 650 2020

Kawasaki Ninja 650 2020

Save the sport tourer! With the Ninja 650, Kawasaki has created an exemplary representative of this class and (hopefully) solved the problem of the new generation. The stable chassis and the decent two-cylinder will delight beginners and advanced riders alike, even at a brisker pace. The front brake is a little too well intentioned, lacking a transparent pressure point despite basically good braking performance. Another plus is the TFT display, which we don't find in the competition at the moment, as well as the grown-up look, which is strongly oriented towards the larger Ninja models.

Aprilia RS 660 2021

In 2021, the Aprilia RS 660 can be seen as the last true 600cc supersport, because with its sporty seating position and high-quality chassis components, it hits the sweet spot between suitability for everyday use and trackday potential. Thanks to the comprehensive electronics package, nothing is left to be desired on the road or on the track - and you can't complain about the powerful two-cylinder anyway. A great package for all those for whom 200+ hp superbikes are too much for everyday use.
