During last service I realized I have an unusual logo impressed in both the cylinders: It might be a "mondial piston" sign but I don't know whether they're OEM pistons or an aftermarket Big Bore.
Can someone have a look to his engine and tell me if matches the sign?
:)

I was sure I have seen these before, so I checked and I can confirm they are 100% standard.

My special has a 750 engine and my barrels were standard bore.

Mondial Piston does (did?) also alloy casting, there aren't many in Italy so is not surprising to know they were one of the "elected"

I am preatty sure there were others, Ducati always had several suppliers for the same item.

Yes, I know about that and it makes harder to find infos about such pistons just for the years of change.

Update: I just received a mail about the question: These are OEM cylinder and Mondial Piston was not the only supplier for Ducati so you can happen to have or not the logo on your engines... Ok, Now I know that Dukess runs fine not because of 780cc breath!
