Worn out rings will do that. If they have too much play in the groove they start vibrating and will chip the piston.
My first guess would be sand but the sleeves look too good for that.
I'm not too knowledgeable about motorcycle engines but I've seen loose rings lead to cracked and chipped pistons in Diesels from overfueling.

Looks like the usable service life was reached with that set of pistons huh?
I would assume that you could get another 27k out of a re-fresh but that would mean timing chain, and bottom end?
Please elaborate.

Well the problem started at 22k miles, so I'd hope that's not the lifespan of the pistons. I'm inclined to go with HotIce, but there didn't seem to be any scoring of the liners. Could that damage could happen without leaving some scars there?
Oh and now we're at 28.5k miles. (Someone has to be at the tip of the spear.)
Oh it was the vertical cylinder piston that took the hit. Vertical cylinder also happens to be the cylinder the tech noticed was sucking in all the crankcase vapors.

Thanks Anti Hero, It will be 5 years before I reach that mileage. now the question is, how much would it cost you? Since you are a Ducati ambassador, will you get any servicing discounts?

Yep. It's called my warranty! It's up in two weeks, though. I can get an extended one for North America, but since I won't be here it would do me no good. If anyone can put me in touch with someone who can sell one for Europe, I'd be most grateful.

I must have missed this part in the other thread. That's disconcerting. What caused that to occur?
That now makes sense why it's so covered in burnt carbon!
Dennis, do you consistently use a certain type of gasoline? I.e., Shell V-Power, Chevron Techron or BP Invorgorate with the additives that supposedly fight carbon buildups? I read somewhere that they actually might work over time. Good luck with the warranty for your trip. As an alternative, maybe we can start a PayPal "slush" fund for you. I'd consider it an NPR-type reader contribution model for your ride reports 
Yeah, logic would make me think traces of damage be present in the matching sleeve too.
Unless different metal hardness between rings and sleeve played a role and had the ring take the blunt of it.

Dennis, i'm on the warranty thing.
I need your confirmation regarding Ducati authorized warranted services and maintenance.

No idea. I asked if I could vent the crankcase to the atmosphere and the answer was no.
JeffD: Shell and Chevron--and always high-octane, of course. NPR-like slush-fund doesn't sound too bad to me, especially if I can't get an extended warranty!
Phl: Not sure what you mean. Confirmation that I still have a warranty? If so, then yes. I do. It's good until the middle of the month I believe.

Certain snake oils do have a minor affect but there is no replacement for a proper FI service, SeaFoam, or straight pure water. Water is always the best by far but should not be done unless you know exactly how to do it.

Uhhhh....not normal. Anyone ever seen this?
I would like to see the skirt ,and cylinder,of that piston, the land area looks peened like it was getting hammered, These new pistons a very tough, not brittle. The carbonized oil buildup is most likely coming through the guides. Throttle closed deceleration with the huge bore creates a massive vacuum.
