Had a crazy idea today: why not a gas can that can mount directly on luggage racks made for Givi side cases? That's the luggage system I have on my Vstrom. Top case is always there, on an adapter plate. I usually don't use the side cases unless going on a road trip. There are rides in my state where it would be really really nice to have extra gas. What I'm thinking is a metal gas can (preferably aluminum to cut down on weight), with hardware welded on to snap on to the rack just like the Givi side case would. Does this exist? Has anyone fabricated their own? I've looked into ways of carrying extra gas, but so far they all amount to "can that requires a special carrier" or "Rotopax. which is quite expensive and would require all-new luggage." As I have the DL1000 Vstrom, gas mileage isn't so great. There are rides where I would feel a lot better if I could carry an extra gallon or two of gas. I very nearly ran out around New Year's, emerging from 100 miles of forest road with not quite enough gas to get to the next town.
