    Cheers Erik,

    I guess the tank braces the subframe somewhat and the rails for the DirtBagz will also help. If all else fails I'll go on a diet:D

    Whose bike is this?
    I met the lad owner of this bike in Daraj (Libya) at the petrol station last november. He told me about xtank and where to get it. I got it and i am plenty satisfied. Thanks!

    I have lost gascap's vent valve, and the question is: does the vent valve let air go in or let overpressure go out?

    Hi Ciropetiro,

    No sweat. Vent valve lets air in (petrol out>air in) and blocks petrol out when you accidently put the muddy side of the bike up :D Now the blockage has left.
    You can still ride with it. (Max actually did last year during the Eastern Europe Rally if I'm not mistaken)

    Nice to see a pic of Rolf's bike in Libya btw
    (that was actually the 2nd Xtank-prototype he is running)

    Erik / Max

    Any consideration to making a similar one for the F800/F650GS twins?

    Actually I already had a F800 in the workshop to have a peek :D

    I can do plenty, but only if people accept, that it won't combine with the bmw-touring cases. As far as I can figure out now, the others, the aluminium Zega/TT cases keep clear of the space I wanna use, but the original bmw plastic stuff is exactly in the space that I would like to use.:wink:
    There might be something in the pipeline.
    Let's have your suggestions (and I will go the other way of course:D)

    picking up my x challenge at the weekend,

    has anyone used the aux tanks with apnniers? i hope to use my xchallenge for rallye work and long range touring and worried that the weight of tank/fuel with a loaded pannier may be too much

    any advice or experience much welcome

    The BMW plastic luggage is garbage, as proven on the 1200GS Vario bags, which is what they are, but all black. If you can do something that fits like on the X Challenge and holds about 10 litres that would be ideal. So long as one is still able to attach luggage such as Touratech's Zega, or Givi or Hepco Becker, where the panniers attach to frames that extend past the bike's frames, I think you will have a very good market. :thumb

    Dirtbagz are your best best, soft luggage is ideal, no dents.. etc.

    The tank holds 7 liters. For me, it was good for 170 km before the fuel in the main tank begins to get consumed.

    Hard luggage wouldn't be a good idea unless you replace the aluminum frame with a steel one, like the one Touratech provides with their panniers.

    any one have a pic showing difference between the 2 frames or is it more a case of make same rear sub frame from steel and not alu

    Sorry if this has been asked and answered before, couldn't find it, but will this tank mount with the touratech pannier frame and zega panniers on an X Challenge? Anyone have any pictures of this setup?

    Afaik, nope, they won't fit without any one off fabricating. However, the subframe for the Dirtbagz blend in very nice with the Xtank I've been told.

    I agree with GB. 10 liters would be spectacular, but anything over 7 would be workable.


    I'm going with a Great Basin soft luggage setup, so I could care less about how it works w/panniers.

    Fitted my tank today, simple and works great. Thanks for your time and effort. Can I shorten the breather tube a bit to keep it away from luggage?

    Of course, no problem. I've done it before. Just don't forget to fasten it with a tiewrap, or you'll surely loose it
