I do drive it careful on the bumpy stuff or when I have water on board, although the water doesn't seem to make much of a difference other than its slower to pull away from standing start etc and the usual precautions you take when there's a load on board, there's still quite a bit of bounce in the suspension though. I got 650 tank in back, I 've had it full a few times but don't have much need at present. Usually have 350 - 400 day to day, i find it very easy to drive.
Thanks to all for the comments
