2-up on a Wee, or only a Vee?
I'm considering getting an adventure bike for the first time to do longer 2-up touring with my wife. Should I even consider a 650, or is a 1000 necessary for 2-up touring? 90% paved roads, though not highways unless I can't avoid them. My wife and I in gear are probably ~420 pounds and ideally there's another ~40-50 pounds of camping gear I'd like to pack on. The 650 appeals to me because they are more readily available and cheap, but I don't want something that's going to keep me constantly shifting on the twisties.
Aside from the 650 vs 1000 debate I'm also considering a BMW GS, probably an older 1100 when they were still carb'd. Obviously y'all are biased, but anyone here have some viewpoints on the VStrom vs a BMW GS?
BTW, I've previously been a cruiser guy (currently a Road Star that doesn't handle for s&*$ in the corners) but I would like to be able to take "the road less traveled". I have also found the cruiser seating position to make my tail bone hurt after only 100 miles or so unless I've got a backrest. I've never tried an adventure bike but I imagine the upright seating and lack of a seat back would possibly suit me a lot better.
