I think the 4 valve service is about 50% more than a 2 valve bike and from what I read quite a bit more difficult to learn. The S4 (916) engine have had issues with flaking valve rocker arms, so a very good thing is if they have been replaced.

Some of the important parts, such as main bearings, valve guides, cylinder walls and clutch bearings don't last forever. It largely depends on use and maintenace. Ducati focus more on low weight and high performance, so maybe comparing with a BMW is unfair/irrelevant...

Some tech info is available on Ducati.com > Bikes > Models archive

Yeah, I get it. I didn't mean to compare apples to oranges but I still wonder what might be considered a high milage Monster.  I guess it all depends on how well maintained the bike has been and how it's been ridden?   I just don't think I've seen many for sale that had over 35K on them.....so would 25K be a higher milage bike?  ....more?  I dunno. Just curious

A low mileage bike is good if its been looked after. Anything under 25k miles is low in my book. If you can find a bike that has the add ons already paid for it will save thousands. Pipes, cosmetic, brake or suspension upgrades and ecu tuning can be substantial. Plastic tanks can be ruined by ethanol fuel blends and steel rusts so it depends. The M900Sie will have better suspension and brakes than the S2R800. The 900 is more old school and S2R pretty.

How big a rider are you? I found the S4 a roomy substantial bike and the air cooled versions very compact. Im 5'8" and 200 solid with short legs so I found the air cooled 900 a nice fit. A customer who is 6'6"-6'7" with limbs like a Mantis sold his 900 and got an 1100 Multistrada because at 50 he couldnt fold up anymore.
I prefered the old style grunt of the two valve motors for street riding.

Some Ducati specialists here will know details on when plastic tanks took over some model runs.
Good comment about preferences .

When my engine was first opened at ~30,000 miles (for a big overhaul and tuning) there were NO measurable wear on anything. I rode it hard, but did all services on time plus further TLC. I'm sure it could have doubled that with few/no issues.

Plastic tanks on all S2R/S4RS (IIRC steel on S4R), steel on S4.

Cool!  Thank you!
