The rear subframe on the new '09 Bergs is plastic, same material as the fuel tank and is a great potential extra fuel cell.
see here http://www.husaberg.org/index.php?na...r=asc&start=15
It has been tested now with no leaks from the fasteners etc, and has a 4 litre capacity, ~50% increase on standard, not bad.
Fuel is mainly to the left side, but given that it is carried low, should not be a problem with bike balance.
Wall thickness is approximately 3mm. This should be more than enough material for the vent fitting (plus sealing goo). Fitting the balance line, would be best to do similar to the fuel pump with a mounting plate/gasket goo and bolts.
With the standard 8.5L it will give 12.5L all up, that will be good enough for Condo and Yilgarn etc. all with the standard slim line body work
Great stuff to be able to do that and use the stock body work.
I reckon some clever Swede had this at the back of their mind with the design...................why else ?? and given its the same material as the tank !!
Plus it means that only about another 10 L needs to be found with the larger Safari tank for the long range rallyes
