Pros and Cons in comparison

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.

lively engine

super-agile handling

Supermoto mode as standard

mature chassis

top brakes

sharp TFT display

connectivity (optional)

Optics not to everyone's taste

price high for a 125cc bike

KTM 390 Duke 2015

"I'm not a girl, not yet a woman" sang Britney Spears in an innocently erotic voice, trying to make the whole world believe she wasn't already dating Justin Timberlake fi...Well, in any case, this is a transitional phase, as the 390 Duke also describes with its essence. No longer a small Duke, but not yet a big one either, the 390 is right in the middle. You shouldn't underestimate it, but you shouldn't expect too much either. If you keep this in mind, you will have a lot of fun with it, even on a not too fast race track. (However, not too many thousands should be on the road then.) Feather-light handling like a moped, but already as strong as many a 600cc funk bike from the last 10 years.

Anti-hopping clutch

pleasant performance

compact geometry

low weight

a little tight for tall people
