Impossible to avoid the 5% ethanol containment unfortunately. For longtime storage I guess you could always use alkrylate fuel. It does not contain ethanol.

The nylon Arcebis used for the tanks on Ducs and KTMs in the past, absorbed the water that precipitates out of the gas. The swelling deforms the tanks.
KTM tanks grow in length and become very hard to put back on the bike, making modified rear tank mounts a must. It can also give a mumps look to the paint.
I hate having to put my tank back on my SD
Luckily not a problem on cars...
