Hi anyone, we need 3 double whopper tanks with cheese to go for XR650Ls (XR6 will fit). The Acerbis plastic 21L is OK but has weak front mounts - around 36L on the front is better.
Any tips or leads in the UK on making them from kevlar/grp or even plastic? I know grp can it be home made, but how? Africa Queens do a 36L ally one at - but for 700 quid! We could probably get our own made from ally for less, but untested ally is not so desirable. Anyone know of XR rally preppers in France that may do big tanks?
We dont want under seat or side tanks - just a big front tank and a 10L jerry without having to sell the bikes to pay for it.

thanks

Hi Chris,
I've searched high and low for a big XR tank in the quest to build the ultimate overland XR. Unfortunately, I think the African Queens is the only big tank currently on the market, and I wouldn't buy one without seeing it first hand.

However, I've had some other interesting leads: Alex Marr found a 40 Liter alu tank for his XR400 in Paris, I think. I can't dig up the email with the details though. My hunch is that that tank was made by African Queens, but if it is made elsewhere and is priced more reasonably, I'm pretty sure that you could make it work on the 650.

Also, check this out: http://www.horizonsunlimited.com/ubb...ML/000021.html
Apparently, Acerbis used to make a 40L tank for XR 6's long ago. I saw pictures to prove it. I called Acerbis asking for information on this tank and the U.S. reps denie that there ever was such thing. Contact Andy, he sold this tank to a guy in Europe and might know where it is now. I'm trying to get my hands on one too.

As for the weak Acerbis tank mounts, you'll actually find that the rear mount is actually the one that's prone to breakage http://www.geocities.com/wwbagwell/fueltank.htm)
I've always expected the front mounts to give out, but even after a couple years of riding my bike on motocross tracks, in Hare Scrambles and on nasty fire roads, they've held up fantastically. But I also don't trust them and here's what I plan to do to rememdy them:
There are three nuts molded into the tank for mounting it on different bikes. If you fabricated a thick, strong plate that bolted into all three nuts, you could extend that plate downwards and have a brace connect that plate to the tabs that come off the frame. The frame tabs should definitely be reinforced. I would think that a very heavy rubber grommet between the plate on the tank and the brace that connects to the frame would be ideal, allowing it to flex just slightly. I don't see any reason why without some experimentation you couldn't create a very robust solution for the front tank mounts.

I'm also curious as to why you don't want to use the Acerbis XR650R rear tank. Will it be in the way of your gear? Sure, it doesn't fit the bike in stock form, but for the price and headache you're going to weather trying to fabricate a new tank, you would probably be better off having the 650L subframe modified to accomodate that rear tank - something that I'll most likely attempt if I take my bike over on my next trip.

Please let me know what you end up doing. Shame that such a fantastic bike has such limited fuel tank options.

Cheers,
Wright

Has anyone seen the price of the XR650R rear tank? I can't see where they managed to fit in all the Gold......

Hi Wright
Looks likes the last remaining xr600 40litre tank dissapeared in the sahara. The bloke didnt get in touch with you as promissed ? Sorry, I thought it was a done deal.
Andy
ps. Hey Chris, this thing was so big it put the price of crating/shipping up all on its own. Double whopper!!!!

Hi Andy,
Nope, no word from that fellow. No big deal though - I didn't take my bike with me to Africa this year, and if I go back, I'll work out some sort of Jerrican solution - it actually sounds easier anyways.

Also just bought an 1150 GS which I may take someday- who knows?
Thanks,
Wright

FYI, AB above has a guy in Cairo making 39 litre steel jobbies for $150. We've ordered 3.

Hey Chris - be sure to let us know how the build quality and ergonomics are - and send along pictures. I'd like to add the info to my XRL site.
Cheers,
Wright
