Sitting around is one of the worst things for any vehicle. Mine is my primary transportation and gets year around use. I'll probably go 200,000 pretty easy unless is gets wrecked.

I've done a couple of searches on this subject and can find no direct answer. The question is, "with normal maintenance and no abuse, how many miles would you expect an engine/transmission to last before major costly repairs could be expected?" I'm thinking in the '09 thru '12 years for a touring bike.

What he says...
I work on heavy industrial equipment which is designed to run indefinitely based on doing certain maintenance work AND inspections at regular intervals. IMO Harley are designed the same way... there is nothing lightweight about them, they are made to last and be rebuildable.
Maintain it well and limit modifications to something resembling stock and they should last indefinitely.

I have 40k trouble free miles so far. I changed the compensator myself because of the 09 issues.
I also had an oil analysis done:
"You have more than doubled your oil change, and your Harley handled the extra miles really
well. We're impressed. This engine has matured nicely, and if you're still interested in running more miles on
the oil, you could likely do 7,500 next time without a problem. Averages show typical wear after 3,900 miles,
so your Twin Cam 96 wears better than most. The only thing we can possibly complain about is the high
viscosity, though without an effect on wear and no harmful contamination to speak of, even this isn't much to
get excited about. Nice engine!"
With results like this, I expect it to go 100k.
