I remember when those first came out, I was at an HD dealer and I asked the salesman, "What do you think of it?"
He said, "It's the answer to a question no one asked."

The V-Rod has a plastic tank too.
Doesn't really count it is a hidden fuel cell under the seat, I don't know what material they are made of but I'm not aware of a problem with them. In fact there are aftermarket larger fuel cells. - Gene

I don't know what your counting, but it is still a plastic tank.

Yep I should have qualified my post. I'm lucky enough to have the only Harley model with a plastic tank problem. - Gene

Under the seat means hidden from view. If it expands who cares Unless it leaks.

I wasn't referencing HDPE. So if PEX is bad then HDPE must be worse unless it is fluorinated. Some research by P. A. B. Carstens, J. A. De Beer, and J. P. Le Roux;
New Surface-Fluorinated Products
, discusses the benefits of surface fluorination of PE containers for insecticides, PE fuel tanks, and also for HDPE pipes. With examples of the reduction of permissivity by factors between 100x and 1000x.

That's interesting. EPA SHED testing shows XLPE gas tanks permeate at a lower rate than HDPE tanks. EPA testing on Marine tanks made of HDPE and XLPE tanks showed XLPE rated lower permeation than all HDPE tanks. Plenty of HDPE tanks around on cars and boats.

Well, sorta. I haven't heard of them leaking. I haven't even heard of them expanding. But you can certainly see them. They are not hidden. You can't see the whole thing, but you can certainly see much of it. Granted, it's not a major cosmetic component like a nicely paint gas tank in the traditional location.
I wonder if any of them leak.

I've been scouring euro/etc ebay sites for Ducati gas tanks. I was looking for tanks made of XLPE/PEX -like a picture earlier in this thread (Reply #1228 page 82). The listings that have a decent shot of the underside all have the nylon triangle/arrows molded into them. I'm guessing Ducati used a fair amount of PA6 in Europe and elsewhere.

I can't post it right now but there is a published ePA review of marine fuel tanks subjected to the shed test.

If anyone made a raw black/ charcoal plastic tank (similar to pic), I'd skin both knees buying two. One for the bike, another for a spare. Given they weren't prone to deformation.
Could be done easily, even if the raw plastic was evened out by cob or soda blasting for a matte finish.

Yes the XR1200 tank problems are known he was referring to the VROD tanks under the seat.

Here's the thing. When I got into doing tanks, PEX was supposed to be the most dimensionally stable plastic there is for fuel tanks. BUT you can't paint it because fuel vapor seeps out through it. Any OEM, production tank that is painted is going to be nylon. Nylon which my plastics people said was dump to use for fuel tanks because it absorbs gasoline molecules whole. (they didn't say anything about water)
Well early on, SOME of our gas tanks would grow a little. Turns out we learn that plant wasn't cross-linking the pastic properly. Since we changed to the new folks who are very conscientious about their work, we haven't had enough problems to get a more reliable estimate about how the stable the plastic is. (so we assume that it's keeping shape well)
Now, I learn through research about fluorination. It could be that the tanks Cycleworks makes and puts through all these processes can be THE solution. Paintable and dimensionally stable.
HillbillyPolack: Yes, you can make our tank look like that with sandblasting / etc. Oh, I'm picking up the mold tomorrow...

I'm surprised that Ducati is still pushing PA6 tanks on the US market.
I personally wouldn't buy another Ducati with this type of tank and somewhat confused why they are still pushing this dung heap of a fiasco on it's customers.
The cost and time to install a replacement for a deformed PA6 tank under warranty, metal seems dirt cheap in the long run.

Hello, I have taken my Duc with expanded tank to the dealer, who claims to have photographed the tank and sent the pics and info to Ducati for approval. It's pretty well expanded and I hope to attain a new tank. The dealer acknowledges that they have been thru this before and have recieved and installed a few new tanks for other customers. However in my case it has been nearly a month and they say that there is still no response from ducati. I am getting the run around. Is there someone I can contact myself in order to try and force some action? Thanks in advance.
