I had to order mine thru my dealer as I couldn't find any in stock. Of course Italy sent the wrong one!
BUT, they realized their error and had already sent out the correct one before my dealer called them about it!!
Just start calling the dealers:
http://www.ducatidealers.com/usa.phpOne of the dealers in North or South Carolina was the only one that had my Termi system in stock. So your seat has gotta be out there somewhere. Remember, Italy is on vacation so if you end up having ordering it cuz no one has it on the shelf, it a'int gonna show til Sep/Oct.
