Welcome aboard ktm950se!!
I'm sure someone will have an aux fuel tank available as time goes on. I doubt you will ever see one from Yamaha itself.

If I get to that level of insanity again. I will post up to show what I have done. I have no intention at this time to do it to this bike. It is easily done. Tour tank has one, so does clark mfg as well. There are others on the MTF forum that have done it many times and have the latest and greatest.

I plan to set the bike up to accept a gravity feed fuel cell that I have on my BMW KGT. It will add about 2 imp gallons to the bike's range.
the worldcrosser rear tank is definitely slick. It will be interesting to see if a very similar one makes it to production. There are a lot of universal box/barrel type aux. tanks that one can hook up, but something molded and bike specific sure makes it look better. For me, I'll just strap a rotopax or two to the slab left from removing the passenger seat. I won't need it very often so will only put it on when needed and I already have a few of them. I wouldn't use the additional range on a day to day basis, so could never justify what I suspect would be quite a high price for an aux. tank.
It does not seem that difficult for someone to take the Rotopax idea and just thermoform a simple rear rack substitute that will bolt to the rear passenger handles. The attached pic is my clumsy wish. Bolts to replace the rear handles and the rack, level with the rear seat if you want to pack across that to carry passengers (or it could be higher), carries a little over 2 gallons, gravity feed from the cross-over tube.Chadx said:
Thermoform initial mold is the main expense. The hardest part is making a flat filler neck and vent that is one-way.
Oh well...Just dreaming.

I would like to resurrect this thread rather than start a brand new one on the same subject. In preparation for my planned trip to Whitehorse next year and some of the additiional trips out of there, I see the need to have extra fuel on board. A friend of mine was going to team up with a molder to fab and market aux fuel tanks. This fizzeled but he had an extra tank that he passed on to me. I'm not sure I have the need (or desire) to plumb the tank for continued use, but I do want to explore the options just case. For now, my main thing is to come up with a suitable method to mount the tank - probably on or in place of the rear seat. The tank measures approximately 13 3/4" wide by 10" ( tapering down to 8 1/2) deep by 6" high. It sits on the seat fine, but the grab rails may be an issue. I'll post up some pictures later today.
Assuming I don't plumb the tank, I will only use it as a portable container and remove it and pour the fuel into the main tank when needed and then reinstall the tank. It will just be strapped on, so removal and reinstallation will not be an issue. If I should decide to plumb it, I will be looking at ideas to tie into the existing fuel delivery system.

I was considering RotopaX at first, but could not come up with a suitable location for their available sizes.~TABASCO~ said:
I hate to be discouraging and if you want a project, knock yourself out, but I think you're going to find this way more trouble than its worth. If your only objective is to have an occasional-use aux fuel container to manually transfer fuel, a cheap plastic fuel container strapped to the seat or the seat area is likely going to be simpler, cheaper, lighter, more flexible, fit better, be much easier to pour/transfer, and be safer. If you decide to do something more permanent, you're looking at a ton of work to mount the tank in a way that is safe/durable, plumb fittings, run fuel lines, tap into the main tank, set up a transfer pump, etc. And this is serious work requiring careful engineering and fabrication with the possibility that an error can burn your bike to the ground and possibly immolate you.ColoRider said:

Rod, I have a Rotopax and have been playing around with locations for it (or them, if I end up with more than one). It will ALMOST fit on the rear seat tray with the handrails in place. There is a bit of interference, but I think snugging the tank down will overcome it. For me, the grab rails will be gone so not an issue.ColoRider said:
I had some not-so-positive responses to my idea of mounting Rotopax vertically beside the engine, and I've had second thoughts but I haven't ruled it out yet. Sure, there is a chance of it being a problem in certain specific circumstances, but riding a motorcycle we are dealing with problems every minute we ride, I don't see the mounting position of the tank as adding terribly to the risk factor. We'll see.

Is that the 3gal size? If so, that is the size/location I had in mind, but did not think it would fit.dcstrom said:

Looks like the 1gal is 9 1/2 by 13 by 3, so even two stacked wouldn't be too bad. I may have to revisit my original idea of using RotopaX.dcstrom said:
Will the tail bag (box) fit on the mount with the gas tanks in place?
It's in the high position. I think if you put it on low you would have a flat tray that would take 2 Rotopax, and then you could strap soft luggage on top of both. Rules out a top box though if you do it that way.tc9988 said:
With the Altrider rack on the high setting it looks like the Rotopax will fit where the seat was removed leaving a relatively flat surface with the Altrider rack for a duffle. I think you could mount a box on the rack and still use the Rotopax in the area where the seat was removed.

I don't have the alt rider rack. I use the Givi offering. Still, I think the 1 gal RotopaX jug may fit with the rear seat removed. Not sure how strong the plastic piece is under the seat for the RotopaX mount, but perhaps with a reinforcement plate on the bottom side, it will be fine. I need to pull mine off again today and look again as it has been a while since I looked at it.
Just a FYI for anyone considering RotopaX, they are offering a 20% discount through the end of the year by entering a discount code.
Details over on ADVRider, which incidentally is the code for the discount...
