The well known problem affecting plastic fuel tanks on Ducatis and some other bikes due to the use of PA6 nylon fuel tanks and gasohol E10 which has caused massive recalls in USA and court cases and huge numbers 25,000 + replacement tanks already with dome issues also seen on some bikes in Europe and even Thailand may not be as bad as though for owners of ducatis built in last 4 years including thai made models .
Reason is that PA6 absorbs water from the gasohol and swells leading to warped taks even cracking and jammed steering , engine problems etc .....
The solution is to make the tanks from PEX a different formula , and Ducatis for all markets except USA since 2009 have all in theory had PEX tanks .
Problem for ducati is that PEX is banned in USA by the environment agency as it does let fumes permeate out of the plastic , so in USA Ducati offer a 6 year warranty on tanks but what you do after 6 year is anyones guess.some companies are now offering after market steel , carbon fibre or aluminium tanks as future options but pricey .
Bike made with PEX tanks should be OK and worldwide it does seems so .
however some earlier plastic tank models sold in Europe , Asia ,and Australia , brazil etc were made from PA6 , and even on lower concentrations of E5 gasohol can warp .
So owners of recent models in Eu and thailand should be fine .
a sticker on the tank will tell u which plastic its made of ,
other makes also affected were KTM, HD sportster sport only , some Triumphs (but not many as triumph quickly went back to steel tanks) moto guzzi , apprillia ,BMW .
