Title: i am not buying any Ducati model with plastic tank. Post by: jerryz on October 06, 2011, 02:03:06 PM I already own 4 ducatis all have steel tanks and are at least 10 years old , I wont sell them but recently i have been looking to buy a new bike or a more recent bike but have decided that it wont be a ducati, due to all the issues with the plastic tanks and ducatis inability to solve the issue with a Proper permanent fix of steel tanks .
So now i am looking at other makes such as moto guzzi, Norton , triumph and even BMW and HD , i do fancy the new commando but the price is high and a long waiting list and its not a 360 crank but 270 . Moto Guzzi v7 is sweet and well made but under pwered for me , the only HD i like is sportsters but I really fancy a parralel twin again .The new bonny is OK but a bit ugly compared to classic ones ah maybe i should get myself a classic bike ???/ 750 commando or 650 triumph or BSA ...hmmmm at least the tanks would be metal.....choices choices ouch i am getting a headache .....better go play with one of my dukes .

Title: Re: i am not buying any Ducati model with plastic tank. Post by: He Man on October 06, 2011, 02:27:19 PM i dont mind my plastic tank. i got mine warrantied.
no coating, no nothing. It hasnt expanded at all. but in my own defense, i do put a regular amount of gas through it ( i fill her up maybe once or twice a week) so the gas never sits. Even if it did sit (for about a month last winter) it didnt expand. Also, my bike has been knocked over way more times than i have fingers to count (okay maybe its just 1 shy from that) and having a plastic tank means i never have to worry about that damn dent, which is great. Will i get another ducati? i hate to say it, but im a ducati fan boy. My next bike will be a M1100EVO.... the only other bike i have my eyes set on is if they trick up the SV650 or the FZ-6.

My M696 had a plastic fuel tank as does my M1100 and neither of those have suffered any deformation (although ethanol fuel blend is not so common in my part of the world). Interestingly, I've had discussions with ducatiz which has revealed that my '09 M1100 plastic tank is made of a different material (PEX) than the plastic tanks fitted to '09 US market M1100 (PA).

I can deal with tank expansion, at least it doesn't keep me off the road. Title: Re: i am not buying any Ducati model with plastic tank. Post by: Travman on October 07, 2011, 03:20:16 AM The new Norton has a plastic tank too. Also, I doubt it will ever make it to the U.S..

The tank itself on the new monsters doesn't get painted which would allow the use of a material that won't accept/retain paint. Title: Re: i am not buying any Ducati model with plastic tank. Post by: bikepilot on October 07, 2011, 04:50:56 AM The bikes with plastic tanks under skins (i.e., pretty much all new ducatis) should be ok, even if it does distort a little, I don't see it hurting anything. Steel tanks rust and sometimes crack, so, on balance, I'll take a plastic tank over steel. With the old ones, its manageable. I need to get a new one for my wife's bike, but the bike is rideable with some hokey mods to move the tank back.
One thing I don't have to worry about with the buell is fuel tank expansion or rust [cheeky] Title: Re: i am not buying any Ducati model with plastic tank. Post by: ungeheuer on October 07, 2011, 05:01:42 AM So what material are the US bike tanks made of? My Australian market '09 M1100 fuel tank...

Post by: jerryz on October 07, 2011, 09:05:31 AM Well as i dont want any plastic fuel tanks it looks as if my options are getting smaller so my decision comes down to a classic Norton commando or another pre 2002 ducati project or an older Guzzi.
Title: Re: i am not buying any Ducati model with plastic tank. Post by: J.P. on October 07, 2011, 01:33:34 PM my '69 commando has a fiberglass tank. Ethanol melted it, constantly gluing the carb bits together. Coating didn't work(must have missed a spot), ended up using ethanol free gas as a solution. Title: Re: i am not buying any Ducati model with plastic tank. Post by: Bill in OKC on October 07, 2011, 01:47:49 PM That sux to have a classic Norton tank eaten by ethanol.
So maybe I missed something - is PEX a better material than Nylon as far as ethanol is concerned? Title: Re: i am not buying any Ducati model with plastic tank.

Pex is not paint friendly. The pex tanks all have outer skins. Title: Re: i am not buying any Ducati model with plastic tank.

I've read quite a bit about Multis fueling issues (a 20k bike, BTW) so I'm wary of their newer product as it is.
Like the bikes I have, I just can't see getting into the laundry list of accessories (again) and any possible goofy manufacturing issue like the tanks. New bikes in the stable = BMWs.

Meaning that US market tanks continue to be produced from less suitable (PA) nylon? I don't know what the homologation issues are. It could be a number of things, including the fact that XLPE/PEX might not be an approved material here. Tanks have to undergo several types of tests including shed and crash. It could be any number of things and I do not have the information to say so. I have a plastic tank, Ducati replaced it, I coated it and now moved on with life. It was that easy. ^ this. I've been involved in this issue for a very long time and the fact that Ducati was changing tanks may turn out to be the most gratuitous act a manufacturer in this situation could have done. The tanks' deformation may not rise to the level of a "product defect" under the law and in the few cases of leaking tanks, there has never been one to flame. Coating the tanks seems to work. Go over to the Multistrada board and lurk a bit -- there are multiple people there with coated tanks who have zero issues -- some >2 years on the coating. I never thought Ducati would come out with a new tank material, I assumed they would figure out some coating that was compatible and able to be legally applied. They didn't, but I know they looked at it. That being said, the amount of effort and cost to coat one's own tank is worth it. You spent $$$ on a bike, I know. Nothing is perfect. You got a replacement tank, coat it and move on and be glad you don't have an Aprilia or a Bimota with a bad tank. Those guys are being told GFY.

I don't miss it, as the KTM (~105hp at the wheel) is plenty fast for the street, is light, and is overall just a ton of fun. I really don't think there is a bike made that can beat the KTM on a twisty road...maybe on the slab, but who cares. The KTM handling is that good, and the power is more than adequate. A lot of horsepower on the street is frustrating to me though, since you can't really use it all without seriously breaking the law...but that's me. Anything over about 90 hp is unnecessary on the street IMO, even if it may be fun at times. You're R1 idea sounds cool...but also like a lot of work. Projects are fun though.

Title: Re: i am not buying any Ducati model with plastic tank. Post by: Scissors on October 17, 2011, 10:07:31 AM Just for the record, XLPE/PEX tanks are approved for use in storing gasoline in the U.S. for power equipment.
However, vehicle manufacturers are subject to the EPA's gasoline permeation rules. In this regard, XLPE/PEX is significantly inferior to PA6. This could very well be the reason for the difference. Additionally, Polyethylene tends to absorb gasoline over long enough periods of time (due to its permeability), a problem which Polyamide does not share. In automotive applications the permeability problem is resolved with a layered fuel tank. Ford accomplishes this with PE (specifically HDPE) on the interior and exterior, which protects middle layers of PA or ethylene-vinyl alcohol copolymer, along with adhesive layers. As you might expect, this increases both the weight and the cost of the fuel tank.

Post by: ungeheuer on October 18, 2011, 03:26:53 AM ....However, vehicle manufacturers are subject to the EPA's gasoline permeation rules. In this regard, XLPE/PEX is significantly inferior to PA6. This could very well be the reason for the difference..... Its also the reason you dont see any painted XLPE fuel tanks... the petroleum permeation causes any applied paint to bubble and lift in fairly short time.

Post by: jerryz on October 19, 2011, 05:39:20 AM Saw a brand new 1400 miles Aprillia RSVR V4 yesterday in UK with badly warping tank its made by acerbis .......seems ducati are not alone also Triumph stopped using plastic tanks in 2008 all Tiumphs now have steel tanks.

Title: Re: i am not buying any Ducati model with plastic tank. Post by: Triple J on October 19, 2011, 11:59:53 AM Triumph then has made a conscious choice to protect their loyalists. Smart move I'd say. The choice to stay with plastic (painted ones anyway) seems like a perfect example of not knowing when to cut your losses and move on. Title: Re: i am not buying any Ducati model with plastic tank. Post by: victor441 on November 13, 2011, 09:25:16 PM I noticed you said you were looking at the Bonnies. Why not have a look at the Thruxton if you like the Norton and Guzzi too? FWIW I test rode a brand new Thruxton the same day I bought my M800 and was sorely disappointed, it felt very bland, kinda like a '70's Japanese twin....a perfectly good bike but very little personality. The Monster has plenty and also ride a Norton Commando and it has even more, though far less performance. Commandos were made with steel and fiberglass tanks at various times and currently the steel tanks are worth big $$$ as the fiberglass tanks don't like ethanol at all as said earlier.

Title: Re: i am not buying any Ducati model with plastic tank. Post by: twolanefun on November 22, 2011, 09:54:22 AM Correct. All the Ca-cycleworks tanks are PEX. Personally, I love my PEX tank, the non-paintable surface isn't that big a deal and the thing can take a hell of a beating. I would love to see a picture, it's my understanding the finish is rough and not that presentable? - Gene Title: Re: i am not buying any Ducati model with plastic tank. Post by: twolanefun on November 22, 2011, 10:06:35 AM So now i am looking at other makes such as moto guzzi, Norton , triumph and even BMW and HD , i do fancy the new commando but the price is high and a long waiting list and its not a 360 crank but 270 . Moto Guzzi v7 is sweet and well made but under pwered for me , the only HD i like is sportsters but I really fancy a parralel twin again .The new bonny is OK but a bit ugly compared to classic ones ah maybe i should get myself a classic bike ???/ 750 commando or 650 triumph or BSA ...hmmmm at least the tanks would be metal.....choices choices ouch i am getting a headache .....better go play with one of my dukes . FWIW my XR1200 is a fun bike to ride, maybe not up to my Monsters when it really gets twisty but still puts a nice smile on my face whenever I ride it. Yes it does have a plastic tank and yes there are reports of the same issues, but there are some good aftermarket solutions, and for the moment HD has been replacing them, no questions. I should point out that the XR has a cover, not quite like the new monsters but the same idea, so the cover does not really get damaged it's the fuel cell under the cover that expands. The new monster will not have any problems since there is room for expansion without affecting the panels. Anyway like I said the XR is a fun bike and since you already have some Ducs, maybe you should take a test ride. - GeneTitle: Re: i am not buying any Ducati model with plastic tank. Post by: xplodee on November 22, 2011, 07:06:17 PM fwiw I just got a letter in the mail that there is a class-action lawsuit forming against Ducati to address the expanding tank issue. I received the letter because I used to own a Sport Classic, AFAIK it did not address the new models of monsters but did talk about the older ones. Anyway, it's about freaking time. I know that people won't benefit from this and only the lawyers will, but at least someone is sticking it to Ducati for screwing everyone with this plastic gas tank issue.

Can you scan and email it to me? Are you sure this isn't the same "pending settlement" letter that everyone is getting ? Title: Re: i am not buying any Ducati model with plastic tank. Post by: DucSeason on November 23, 2011, 05:43:18 AM To the OP:
I have a couple suggestions for bikes you might consider: 1. The Triumph Thunderbird Storm. I demo'd one and it has the hot-rodded version of the Thunderbird parallel twin motor in a package that actually handles pretty darn well. It was a HOOT to ride. 2. Victory Vegas 8-ball. Rode one a couple weeks ago and I was laughing the whole time. That 106 ci Freedom v-twin engine puts out 90hp/110ft-lbs peak and pulls like a freight train. It flat FLIES for a cruiser.
