just to add my two cents, a buddy of mine has a 1200 with a sissy bar and homemade floorboard's for his wife. they ride everywhere together we even road to Nebraska this year, it was around 650 miles, she didn't complain much at all, we would stop every 100 miles for fuel and such, but like I said, no real complaints, maybe she just has so much extra padding, he is about 5'8" and 175lbs, she is around 5'2" and probably 155lbs, the bike still has lots of power with both of them, but I think a more of a cruising bike is best for two up.
