Pros and Cons in comparison

Kawasaki Ninja 650 2019

The Ninja 650 firmly stamps its predecessor (Er-6f). The engine has mastered the Euro 4 hurdle well and serves up a very usable 68 hp, the chassis is simply great for this class, and the weight reduction of 18(!) kilos compared to the ER-6f justifies reverent nods.

Transparent chassis for sport

playful and good-natured handling, excellent brakes, sharp looks a la ZX-10R

resilient engine.

Little sound from the series pot

engine shows slight vibrations

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.
