I am looking for an 1125 owner who can fabricate a rear rack for me that will attach in place of the pillion seat. I would like it to hook up to the rear frame in some way, but still be removable without making any changes to the bike. It will need to be able to support a 6 gallon fuel cell. I am thinking aluminum here unless yo have other suggestion. I tried a rear seat pan, and it is too floppy for the application. Anyone care to try, and let me know what you want for such a project, $$ wise. You can email me at davidg dot gordon AT gmail dot com. |

6 gal cell is going to be between 42-48 lbs in fuel alone, so be careful on how you carry that weight. It's going to be a challange to put that large of an iron butt cel on the back of an 1125 with so little surface area to work with. Good luck. |

Can I just ask why you want to do this? |

More fuel = less stopping = ideal for distance touring. Your range now goes from 150-200 to 350 to 400 miles depending on your mileage. That's some decent range for distance events. |

is it possible to run a split tank, similar to dual hard bags off either side of the tail? If you wanted a more user friendly version, one could rig up some -AN fittings and braided stainless hose into an inline fuel pump, plumb it into a modified gas cap of some sort. I'm guessing you are designing for some sort of long distance baja-type function? |

A couple days ago I rode home with 2 new 1 ton front brake rotors in the trunk of my Uly. Man that really changed the way it handles, that's why it says 11 pounds max and I was way over that. I don't think I would put that much weight up that high. |

I agree that is going to change the handing but how different then putting 100+ lbs person back there? |

A 100+ lb person doesn't have fluid transfer (well it does, but not like a fuel cell). A human also has control over his/her body. A fuel cell is dead weight. |

Is there a way to make the air box cover a "real" gas tank? |

Thanks for the suggestions. As most guessed, it is for LD (long distance) events (rallies and rides). The picture of the givi case is about what I am looking at. I don't have much fab experience, and my only real concern is that much weight solidly mounted on the frame. As has been noted, people move about and don't pose much of a twist threat on the tail section. I don't think 50 lbs on the back will be that bad, and the idea of a split tank may be a better idea. I will then need something fabricated to solidly mount it to the bike. No loosely mounted fuel cells. Anyone care to try or know of an existing system that may work? Thanks. TT |

I can most likely fab something up for you, ill try and draw something out and work out a number($$).. send a pm if you are really wanting to do this. |

What about Rotopax Can add them to a variety of areas like the top of side cases and top case mount. Below is a pic http://www.advrider.com/forums/showthread.php?t=53 3911&page=2 http://www.rotopax.com/gasoline-pack-kolpin-kolpin -atv-accesories-fuelpack-fuel-pack-atv-utv-ga-c-1. html |

The easiest way i could think of would be to pop off the passenger seat, and weld bolt holders to the subframe, then fab a rack that can fit on top and bolt into the bolt holders.then fit the gas cell to the rack. That way you could remove the rack and put the seat back on and it would still be stock. |

Hmm. I like the Uly topcase that Steve shows....and I happen to have a spare Uly topcase laying around....maybe I should find a spare passenger seat to bolt it to Although, for aesthetics, I'd probably fit a wedge of some sort to get it to sit "level". But I'm weird that way. Ok...a lot of ways |

top case is awfully high up to have 6 gallons slopping around. Sounds like an easy way to get hurt. mount some 2 gal rotopax off some side cases and a 2 gal to a flat mount on the pillion to lower the weight. (Message edited by ratgin on May 01, 2010) |

The fuel cell must be tied to the main system. That is the problem with the rotopax jugs. Otherwise that would be cool. I agree it increases the risks involved with riding, but I think it is manageable. A baffled call could reduce the slosh too. |

Well whatever you do your most likely going to have to run a fuel pump from the tank or tanks to fill the existing tank. Unless its higher and you can have it siphon off but in that case you could wear the fuel cell like a backpack LOL |

that will make for an interesting project the no "fuel tank" will add a lot more challenge. |

I believe there is a port on the bottom of the bike fuel tank that will allow a me to tap the aux tank into it. It has been done on the Ulys the same way. With the aux tank mounted on the rear of the bike, it should gravity feed into the main tank without a problem. I only need a way to solidly mount it on the back of the bike. Hence this request. Thanks for all the suggestions. If you have any more that will satisfy the criteria, please make them. I am in no way certain that my plan is the only or even the best way to add additional fuel capacity to the bike, but it seems like it will work. |
