I went from a 1000 to a 650 and thought 2-up might be a problem. I was pleasantly surprised that the bike does fairly well lugging 2 people around. It's not fast but still plently quick to leave traffic behind. The 1000 on the other hand, still pulls like a freight train. IMO, the 650 is plenty for 2-up, the 1000 makes it so you can go fast while doing it. If I was doing 60% or more 2-up I'd probably take the 1000, otherwise I think the 650 would be my choice because I enjoy it more when I'm alone.
