My vstrom does 500km on a full tank...weighs about the same....cost 13k. Youtube is full of videos demonstrating how little of its capability i can or do actually use so i wont be buying any of them just yet. (Never say never!!) Should i start a " we better have a 650xt thread I s'pose" thread??? Fuel...My drz400 does about 200kms if im lucky on its piddly little tank. As does the drz 250. $15 upgrade from Mitre10 fixed that problem. Well, $20 if you include the two cam straps i use to clag it onto the rack. I carried it full of gas from the Waikato to Otago and didn't have to use it. On the subject of weight...if we are talking about serious touring then theres likely going to be around another 100kg added to the bike by the time you head out of your driveway so to my mind these three are the same weight. They all look great to me... id have any of them.
