KTM 125 Duke 2018

KTM 125 Duke 2018

Even in its second generation, the KTM 125 Duke is still the highest-quality overall package in the 125cc naked bike class. Its looks stand out and its equipment is similar to that of larger and significantly more expensive KTM models. As is typical for KTM, the handling comes from the supermoto league, which makes the 125 Duke a real fun machine in tight corners. However, the Orange from Mattighofen should not relax too long on their laurels, because the competition is strong and is already beginning to overtake the ever-popular KTM 125 Duke in some aspects.

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.
