Do the newer (2016 and up) Multistrada bikes still have issues with ethanol causing the fuel tanks to expand? Having owned both an MTS1000DS and a Sport Classic, I'm all too familiar with Ducati fuel tank swelling issues, the class action law suit, etc. etc. But in reading over all the pages and pages here and elsewhere discussing the issue, the chatter seems to go away around 2014 or so. Did Ducati (Acerbis really) finally make a change to the type of plastic used for the fuel tank, or some other running change, like simply leaving room, allowing for some limited expansion? No one seems to be complaining about it on the newer DVT bikes.

Owner's manual states 95 fuel and max 10% ethanol. Warranty "null and void" if over 10% ethanol fuel is used. Rubber parts don't like ethanol and there is a pretty strong consensus that ethanol is at least in part responsible for fuel level sensor failures.

Your original post refers to the problematic models from 17 years ago. The last sentence in your original post answers your question

It's not a good idea to run ethanol in a motorcycle generally. That has nothing to do with the gas tank expanding on a modern Ducati, and everything to do with ethanol having a shorter shelf life than regular gasoline because it absorbs water.
