Pros and Cons in comparison

KTM 125 Duke 2019

KTM 125 Duke 2019

Even in the Euro 5 version, the KTM Duke 125 is the motorbike to beat in the A1 class. Superior equipment, potent engine, good chassis, great display and fun Supermoto mode make not only the heart of 16-year-olds beat faster. The looks polarise, but let the observer clearly recognise the smallest Duke as such. The Duke 125 is not cheap, but it is worth the price.

Aprilia RS 660 2021

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.
