I asked the German Importer of Husaberg, J. Steenbock, this question at the presentation of the 07 lineup and he said:
"Husaberg will not give up the motocross segment. The will come back with the next general revision and bring a motocrosser. The current engine layout has only minor chances in the hightech motocross segment."
I don't know what this means, maybe they're working on a DOHC-engine and surprise us in 08 or 09.
