Anyone out there got the Acerbis 3.9 gal S-model fuel tank on their bike? Please post pics! I've been all over the web but have never seen a picture of one on a bike. I like the look of it (much more so than the Clarke) but am concerned about width and am guessing it sticks out past the seat in terms of width (they have to get their capacity somewhere). I like the ergos of the stock tank but want to go to plastic; extra fuel capacity is a bonus. I'm considering the IMS 3.2 gal but am concerned about fit-and-finish and colour variability of the natural. Comments please!
