"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.
