As long as it's made with a high quality vinylester resin, it's perfectly good, if not excellent. Most home built aircraft and many GTP cars have carbon/kevlar/s-glass gas tanks.

I actually just completed a new tank for my bike using VE Carbon/Kevlar and S-glass.

Additionally, a tank like this can be repaired, on the trail if need be. Once you crack a PE tank, it's all over.

come on come on more info and those sort after pictures!!

Very true I think there are some carbon layers in the tank

I assume you recommend vinylester because of better compatibility with the alcohol content in fuel these days?

Probably Kevlar for the mounting points?

Do you know if Alberto uses epoxy or vinylester resin? I think most countries in Europe use 5% or less of ethanol, don't know about OZ.

north america is 23.6 mj per litre

10% per litre but some provinces are bringing laws in to keep it below 5%.

Out of all resins, PE, Epoxy or VE, VE has the highest vapor encapsulation rating and the greatest ability to withstand chemical etching, whcih could lead to leakage.

Kevlar for it's impact strength and high tensile modulus (yes, to keep mounts from tearing), Carbon for stiffness, and S-glass for binding and finish.

Who's Alberto????

Redacted

how does that stretchy blue latex bash plate work???

i thought this was a ktm build.

maybe we should have a build off......

Dang! Mudders - That looks good

That's actually modeling plastic for the beginning of composite bash plate mold.

It is a KTM thread I guess I actually would consider it a build thread using a KTM. I guess you didn't read back far enough to realize that I'm just supporting the fact that fuel cells/tanks can and are made out of composites and simply posted a pic in support of that.
Sorry, I should've realized that most KTM guys can't appreciate anything unless it's orange. My humble apologies.

I have removed the photos so as not to confuse anyone.

MUDGUTS, Great build!

Corrected.

I don't consider myself to be a BMW guy, I just own one at this current time. I'm an admirer of all motorcycles and have owned almost every brand at one time or another.

And while I was down there doing your shoe laces I realized that there is a string hanging out of your Daisy Dukes. You might want to tuck that back into your thong. How's that for a little thread banter?
