I sold my ninja 650 at about 120'000km. It was top shape.
I expect my versys 650 to go 200'000 or more.
I have never heard of a technical hard limit to bikes: everything can be replaced (until parts are no longer made).
The usuals (chains & sprockets, forks seals, wheel bearings, battery, valves adjustments) all within 100'000 km, are certainly not reasons to sell.
But I can imagine a few thing some owners more or less don't want to deal with after 100'000km:
-brake disks getting thin (on my radar right now)
-fuel pump and stator to fail: both can be inspected. ultimately replace.
-coolant pump to wear, but I'm not sure it would come up before other big items.
-engine to loose power and increase blowby/start consuming oil: if I'm not totally misguided, re-sleeve or enlarge pistons/re-hone cylinders.
other guesses (purely based on what's moving or beaten):
-timing chain guide wear?
-all internal bearings and gears?
The problem is the sum of repairs. You can pour 4000$ to get another 100'000km but but what of it ends up needing 7000$? It may be less expensive to buy a new bike 9000$ while getting 2000$ from the old one, but good luck finding a capable owner that will job most of it himself thus think it's a deal.
It would matter even more if you took 15 years to get there and the parts are no longer available...
