I am not a fan but I'd go test ride the BM...Husky 650 with my passenger. My dealer was trying to get me to ride his the other day. For what it is, it is probably the best 2 up street single offered just in terma of size and ergos for 2 people. I sat on it with my son on the back. I'm 6-01, 210 and he is 5-10, 225. Lots of room.
The KTM Adv was an awesome 2 up bike, and don't fear the wrenching. It is intimidating at first but it was engineered to be worked on.
