    So I am quite interested in picking up the F800 GS for doing some long distance trips in the next few years. However, my main issue with it is the dinky 4.2 gallon tank. Even with the supposedly great mileage that the F800 is supposed to achieve, that tank will be good for only about 200 miles, give or take. As of now, there are no larger aftermarket tanks available (and who knows whether such tanks will become available soon, or if perhaps BMW will come out with an adventure version of the F800 GS with larger tanks down the road - although that really doesn't help me right now). The other bike I am thinking about picking up is a KTM990 Adventure. Although the KTM is also plagued by a small tank, larger aftermarket tanks are available.

    So in thinking about picking up this bike, I would like to know if anyone has any realistic ideas for carrying a significant amount of fuel if aftermarket tanks do not become available. This would be in planning for a long Alaska trip or a South America trip, so it would have to be rugged, able to be carried on a fully loaded bike, and practical enough to use day after day. I would like to get 2 extra gallons on the bike, although 4 more would be awesome.

    From looking on the internet, the best idea I have come up with is this:
    http://www.rotopax.com/rotopax-rotopax-fuel-pack-atv-fuel-gas-container-gas-can-fuel-m-3.html
    I could see taking two of these (4 gallons, 32 pounds when full) and mounting them between the rider and the top box trunk. Its not ideal: I would like to get the weight lower on the bike, but its not bad. What do you think of this? Would there be a bombproof way to mount them on the back of a side case?

    Any other creative yet functional ideas?

    Better idea.

    Go to tourtank.com. I have one on my Concours, and my next bike (possibly a new 650GS or a Ulysses) will be plumbed for one as well.

    I do a lot of long distance riding (IBA kind of stuff) and while I don't have it on my bike all the time, it is nice to have when you need it.

    Those tourtanks look sweet. How solid is the mounting - like in a pretty fast dirt spill will it hold up? Looks like you can mount it just about anywhere too. Thanks for the tip.

    Look at the 5 Liter metal fuel cans HERE under options for the trailer. I know someone who got the whole trailer setup with fuel cans..... I'll have to see if there is a logical way to mount those (or similar) cans in conjunction with a set of Caribou Cases (after I get a bike to put them on...).

    Who makes the cans that BMW had on that bike they were testing in Africa last fall?

    On my Connie, I previously had a 4 gallon RCI cell, but it put me over IBA/Team Strange limits. Then I bought the 3.5 gal. tourtank.

    I built an aluminum rack for the tank which bolts into the subframe of the bike. When the cell isn't on there, I use the rack to hold my Givi trunk.

    The whole saga can be seen here. The page is a little confusing, as I changed tanks.

    As far as sturdiness, the tank itself is solid as can be. I've dumped the bike before with the tank attached on a distance rally, and it's not going to break or split. The real test would be how sturdy your own mounting system would be. The other risk, is how heavy the bike would be to pick up in a fall with a full tank. A friend with a VFR went down on gravel with a full auxilliary tank, and had to disconnect the whole thing to get the bike back up. YMMV.

    If you do go this route, please let us know how you plumbed the tank. This bike (actually the new F650GS is more likely) is very high on my list of possible new bikes, and I'd love to know what other people have done in this regard.

    If you really wanted 4 gallons this would be a pain... but just to add "variety" to the thread ....

    I sometimes tuck a couple 32 oz. MSR fuel bottles mainly for "insurance".

    http://www.msrgear.com/stoves/fuelbottle.asp

    They are not very expensive and the small size means they can go to where I have some free space. I found a small plastic funnel to take with me for refueling, but generally I use this just for insurance ... refilling 8 of these at every gas stop would get old quick... :lol3

    I'm interested in this subject as well, as I'm really liking the looks of this bike (time will tell with a test ride...)

    One option would be to mount one of those rotopax fuel containers to the inside of the right hand hardcase, since this bike has a single side exhaust on the opposite side. I'm sure something could be fab'd to the case support frame to fit one of these in that "slot" area.

    This thought comes from looking at the "RTW" 800GS thread bike with the pelican cases. There's a pretty good gap on the right side between the case and the rear bike frame.

    i'm interested too.
    Have been looking to the tourtank 6x15 & 6x50 inch versions:
    http://www.coyote-gear.com/6inch.html

    indeed, maybe it's possible to mount one of them on the right 'slot'.

    FWIW, I rode around Alaska, Yukon, and NWT on a F650GS (close to the same tank and fuel range) for a month and only needed to use a 1 gal. jug once-- on the Dempster.
    just my 2 cents

    Is there really a spot on this planet where a 200 mile range is not enough?
    I may be wrong but, I stop at every gas station I see if I'm in the bush and only once on HWY 6 from Utah to Yosmite did I almost get caught, after I made the mistake of passing a gas station after seeing a sign "next gas 40 miles". Of course that station was long gone when I got there.
    Carrying extra gas IMO gives you a too comfy feeling and you won't stop till your almost out, just to tell your buddies "I went 400 miles without refuelling" What if there no gas station at the end of 400 miles?
    My advice is, if your in an area where gas may be a problem, buy a gas container, fill it and then toss it when your done. A lot cheaper than spending a large amount of money on something you may only use once.
    Otherwise buy a KLR with an IMS tank, good for 350 miles.

    I ran out of gas on a KLR in Peru once, and not for lack of trying to find gas. And it would have happened multiple times in South America if the KLR's 300 mile range was instead a 200 mile range. Sometimes you just don't know when you are going to be in a situation where you will run out of fuel. A station could be closed, or be out of gas. Yeah, I would say that 200 miles is probably just fine in the vast majority of situations. But in the one or two cases where 200 isn't enough, it can really suck.
