If you're talking about the rotopax, mine have proven to be plenty tough as far as abrasion goes, at least as hardy as the aftermarket main tank on my WR250F.. Given the options, I find this to be a fine spot to mount extra gas. 2-1 with an adv tank would be better protected, but that's a bunch of $ that I don't want to spend, and pretty permanent for the majority of days when I ride and don't want to pick up the extra weight. Mine are somewhat protected by the projection of the utility cases behind them, which is weird, but when it's gone down, the larger case and (once) the mount seem to take a bigger hit than the gas container.
If this bothers you, stay away from the "extra fuel" threads, where the leading method of choice seems to be coffee bags...bungeed on...now THOSE give me the heebie jeebies.
