Planning to buy R1100GS with 41 litre TT tank. But i've heard storyes that the tank acctually doesn't fit that much gas. Fits around 35 litres or so. True?

Any experiences with that tank?

Hi Margus

If you do a search on www.ukgser.com for this tank, you'll find loads of info on its real capacity.

I've been running a 41 litre TT tank for quite a few years now. I find it perfect for travelling outback and anywhere else for that matter.

I usually end up with about 35 litres between stops but once last year I did 37.5 litres at which stage the fuel pump is just starting to hunt for fuel.

Generally speaking, you do notice the full tank, but one has to remember that it's after the bike has been running empty so you should feel the difference.

You have to rotate the fuel pump and also change a supplied metal wire, that holds the actual float.

I have seen and read about getting rid of the air reservoir at the top of the tank by drilling holes which allows one to hold 2 litres more fuel. Having seen what expanding fluid does to containers when it gets warm, I wouldn't suggest that it's a safe route.

Generally speaking I work to this standard, two up heavily loaded, sandy tracks 500 Klm's, normal tracks 600 Klm's, bitumen roads and hovering around 100 - 110 Km/h for touring, 650 Klm's. If I'm solo then add about 10% and if the bike is totally empty except for the rider add 15%.

I have actually done 770 Klm's on one tank. This was really an accident as the last town I was going to refuel at wasn't there, it was just an intersection of two roads, forcing me to travel sedately another 120 Klm's.

If you do fit it to an 1100 you will need to purchase early model 1100 tank rubbers. They are the rubbers between the tank and the fairing bits. My 1100 is a 98 model and I required the early rubbers. It doesn't fit exactly but good enough.

I would also strongly suggest if you haven't already done so, to fit the fuel lines with QD snap connectors. Things are a bit tight wiht the larger tank and reaching underneath to fit leaking lines isn't a really good idea.

If you fit the tank you will not regret it.

The Touratech tank bag also fits this tank perfectly

Just drived the bike home from Berlin and had a time and lots of mileage to test the TT tank that was already mounted. I got 32 litres out when the 2 bars still were active on FID display. So i think the maximum is around 35 to 39 litres.

Very pleasingly good thing about the tank is the dynamics - it's very lighgtweight itself, has extremely low mass centre when fully fuelled up, the two slopes are sp big that they cover your knees from the coming windflow enough too. And it doesn't affect the driving at all. Feels like you drive with original tank, altough you have extra 15 litres or so.

I think you're right about it - don't want the original tank anymore. Would be too lazy now to fill up every 350 kilometres if i have a chance to fill up every 600 km. True long distance option.

Recommended for travelling boxer GS owners.

Hello.
The tank do have a capacity problem that can be solve with TT pump kit
Cat.No:05-100-0014-1.It's not on TT web cat.but i can send the PDF about it.With this you can use 39L.

Thanks adamiko!

You find my e-mail from my details, i'd be interested in that PDF file.

I've heard that there's possible to drill some additional holes into fuel collector so it takes couple of litres more from the tank, not sure if it takes 39L with this way... Here's good illustrated link for this procedure: http://www.gooseontheloose.com/tips/...tm#41lfueltank
