Main problem is with the fuelling (very rough between 3k and 5.5k with no power) and the slipper clutch causes an inability to select neutral, even at standstill. These are the two that most other users get.
I waited six months for a fix but Benelli were either unable or unwilling to resolve these issues. I had many other problems, some fixed some not.
I agree its stunning but that mens for nothing if it doesn't work. I suggest you get your mate to check out the Benelli users forum at
http://pub2.ezboard.com/bbenelliforum before he makes such a momentus decision.
One point to note is that my bike was July last year some are saying that year's models are slightly better, ah well.
Cheers
