Pros and Cons in comparison

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.

powerful engine

extensive electronics package

sporty chassis

nice sound

low weight

sporty look

poorly readable rev counter

Kawasaki Z900 2020

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, even if the option of a quickshifter would have been a nice extra. Apart from that: great shot, Kawasaki!

powerful four-cylinder

great handling

good equipment

aggressive looks

value for money

Menu navigation somewhat tiring

missing quickshifter option
