"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.

The KTM 790 Duke L is an absolutely sporty naked bike with a high fun factor. Whether a beginner rider can handle it depends very much on his or her personality and riding behaviour. There are certainly motorbikes better suited for learning, but sporty radius hunters will hardly be satisfied with anything else. The 790 Duke L is also rather unenthusiastic about everyday rides in the city. On the country road, however, it's a blast, even with only 48 hp. Simply a fun bike as it is written in the book.
