went through the same process ... decided weight of bike was all important. next in line was complexity of machine and parts support in remote parts of the world. since my objective was a mount that would take me RTW.
ended up with BMW R80G/S .. first of the dual sports at 368lb dry.. with 9 gal fuel about 425lb. shortly after receiving my R80G/S which had gone through a frame off restoration by Beemerguru. hated to scratch R80G/S, but it was coming anyways.
laid R80G/S down in grass, then tried to pick bike back up.... No problems .. picked R80G/S right up no sweat .. this was with about 4-5 gal fuel and no luggage.
try that with some of the 1200cc class bikes suggested .... argggghhh my back aches thinking about it
