2 of my friends just bought 990's. One bought the 990 SMT and the other bought the 990 Adventure.
I rode the SMT and it is a lot of fun. Plenty of power and feels like a big dirt bike on the street. It did take some extra input to get it lay over in the turns but other than that I felt comfortable right away on it. The only other thing that bugged me was the abrupt nose dive in between shifts. I think this was due to it being not broken in and too soft of compression in the forks. Wheelies over the top of hills were fun. You could get into a lot of trouble on one that's for sure...
