KTM 125 Duke 2021

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.
