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: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
I was considering RotopaX at first, but could not come up with a suitable location for their available sizes.~TABASCO~ said:Rod,
Im looking to build a few for customers soon.. I can do any shape or style, with any features.. If your looking for simple and cheep rotopax prolly the way to go....
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: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.
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 was considering RotopaX at first, but could not come up with a suitable location for their available sizes.
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:Rod, I have a Rotopax and have been playing around with locations for it (or them, if I end up with more than one).

No, it's the one gallon - but you could stack 2 of them if need be (or 3, but I wouldn't like to be stacking that high).ColoRider said:Is that the 3gal size? If so, that is the size/location I had in mind, but did not think it would fit.
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:No, it's the one gallon - but you could stack 2 of them if need be (or 3, but I wouldn't like to be stacking that high).

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.

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:Thats the location I thought of placing a Rotopax. Do you have the Altrider rack in the low or high position? I can't tell in the photo.
