The wife and I used Peg Packers to keep from putting extra weight on the pannier mounts, and they mount low. 2, 1gal. jugs on each bike, F800 and a F658. (I would sell 1 set if anyone is interested.) Very few places you would need them. As other have said the GS’s get really good fuel mileage going slow on the bad roads. But never pass gas!
I'm not saying there should be capital punishment for stupidity, but let's take the safety labels off of everything and let the problem solve itself.
