that completely sucks.
looks like the damange is pretty minor.
as for falling off the side stand, i can see it happen. the side stand on my F4 does NOT give me the most resounding confidence. it has a sort of "semi-stable" position, where it's extended but not fully against the stop. it would be REAL easy for the bike to roll off it in that position.
whenever i put the bike on that side stand, i really put my foot on it (the arm) and make sure it's at full lock before i load it with the bike's weight.
any chance that's what happened?
