It has been my experience in the past with big tanks on many different bikes that the best compromise, and that is what it is, between slender midsection, not too tall top, and extra fuel is the use of the radiator shroud area. This also provides protection for the radiator. The tank for a KTM that uses the radiator shrouds is not too bad at all.

You are right that the larger tank will be bulbus but sometimes that is the price we pay for having the ability to cover long distance.
 
if you look at a lot of these large tanks like the omeromoto and even the IMS i bought direct from the states: they all go really low, past the kickstart lever etc. THAT'S the place to gain capacity!

Dear Gentlemen.

Like nsman, I have taken a hard look on adding fuel capacity without widening the tank.
I even gobbled up a few bears and puffed my pipe to really add needed performance for my braincells.

My solution is as follows;
Do´nt use the tank for more capacity, use the part of the frame which already is the culprit for a wide tank / wide motorcycle: The wide frame from the air-filter to the steering head.
It´s a dead zone anyway, air is not sucked in from the steering stem.

Block the inside of the frame in front of the air-filter and make some kind of device so that when you fill up the tank, you also fill this space up with the ever precious fuel.
I would think that this space could add around 3 liters.

Good, or bad??

Best,

A very, very good idea and I would do so if 3 litres was achievable
Unfortunately, I used a CAD programme to calculate just what volume was achievable( based on a guessed 1.6mm wall thickness) and came in at just below 1.5 litres.
For 3 litres I'd be out there chopping it up now, but not for 1.5.
 
the tanks on the older bergs are the way to go , as mentioned previously the fuel storage and the weight is where it should be , low .

well calculated ausberg .

From these numbers we see that the cost of producing a production run of Berg tanks is viable as the cost of the start up is not a major consideration at this time as long as 750-1000 tanks could be sold in a business cycle. .What is not viable is production past the initial production run,and no doubt this is the major stumbling block at this time for the tank producers.

I lack the background and expertise to question any of your assumptions, but your statement about viability after the first production run seems misplaced to me. In my reading of the various posts on this topic both here and in past threads, I inferred that the major impediment to market entry for Clarke, IMS, et al was the upfront costs.

Is there more viability for a skilled and motivated enthusiast to do the initial design and testing and then sell that to the OEMs?

Hi Satex,
Sorry i missed this,but this was one of those "what if" topics.The numbers I presented depended on the number of tanks the market place could absorb,the cost of the mold etc.Since these were quesses, really the viability of the project was always dependent upon these estimates.As you will recall Lineaweaver was doing his best helping me keep earth in focus.

All this thought is good however, you have missed a few very important points to ponder. For example, you must leave room for a radiator fan and, you must add vertical height to the front for a dry break option. A drybreak will add about three inches or so to the area thats loops around in front of the seat and you must leave room for a steering stabilizer. The volume of one or more gallons of fuel is harder to achieve than most people think. If you try to keep the tank narrow and just try to go lower on the bottom you could run into a few issues. Too low and it won't drain properly to the carb and on the left side, you still must be able to get to the choke and hotstart. You also want to keep some clearance for your petcock from the exhaust header. I think a little wider and taller is one way to do this. You could also try to incorporate the shrouds into the design. There are lots of things to consider on this project and in order to get an extra gallon plus will require the tank to grow in areas that will make your Berg feel like a bigger bike. There's no way around it.

Why not a lot like the Husaberg pre 2000 20 litres tank? Integrated shrouds for capacity and using right hand side space down to engine level and a mikuni intake pulsation powered fuel pump. The low centre of gravity idea from the early days. Was it Acerbis made? Do they still have the tools to modify, if at all possible? I think I´ll have to search for a photo on this rare tank.
The air box? Unless the air volume is there for a reason, the 1.5 litres (?) could perhaps be used to increase oil capacity for laps longer than the normal oil change interval? BTW http://www.bjornnygren.se/ indicates that he is building yet another rally raid Husaberg. Not very much on the site yet though.

If you look on my gallery my bikes got the big tank on, works just fine.
 
If capacity is the biggest deal how about making the seat part of the

fuel cell? just a thought!

Chester at NMS is looking at that for me as well as the dual exuahst fuel cell. Both are not quite what is needed.
BTW how obnoious is that Omerto BIG tank. Is it REALLY bulbus?
 
hi bossy!

great idea and i've often wondered 'why does a seat have to be 10" deep in the middle.

bob
i think the idea with the big tank is that you fit the shrouds still and what the eye don't see don't matter none!' as they'd say in the south!

The pictured has a 5 gallon fuel tank. I am truly sorry I did not bother to take more pictures. In any event the tank extends well under the seat (as mentioned by Taffy) and provides as part of the inner rear fender. (ie it is very long)

Hope this helps stimulate brain cells.

Sincerely,
Dale
 
If anyone is searching for a 21 L fuel tank for the old Husabergs (up to 2000), try www.pitsoffroadstop.de (it´s in German, though). They sell a front tank for 499 Euros. They have a small rear tank as well.
Pit Karches, the owner of the shop, built a FE600 rallye bike sometime ago, which is shown on the homepage as well.
Unfortunetaly the 21L doesn´t fit to the post 2000 Husabergs. :(
 
I just looked at this site.http://www.bjornnygren.se/ Man that is a nice looking tank in two pieces. any one speak that language? would you contact him and see where he got it. Looks like it worked well going by the before and after race photos.
 
pssst...I heard a rumor today......big tank from Husaberg...unknown capacity... I know nothing more..oh yeh by this winter...that is all I know...just a rumor.
 
Hate to be a wet blanket here but two things to keep in mind for the un-initiated;

A) Be sure to factor in legal/insurance costs for ANY accessory you plan to market. Especially something as potentially dangerous as a fuel tank!

B) In the immortal words of "King" Kenny Roberts, when once asked "How do you make a living racing?" he answered, "The best way to make a small fortune racing motorcycles, is to start with a large one....." (same holds true for most motorcycle endeavors unfortunately....)
 
Clear or Yellow but dont really care about style! I just NEED more fuel. Any color as long as its bigger than stock is ok with me. :D
