Got 110K out of my '08 Wide Glide before it started burning a little oil.
Compression / leak down just below acceptable limits at 120K, upgraded to 103" jugs and pistons, reconditioned the heads and added cams.
I ride hard in the twisties and never babied the bike.
She's got a lot of miles left in her.

I think a well maintained engine would easily last for 150,000 miles. I replaced my 883 engine at 65,000 miles with a 1250 engine. The inside of that 883 engine looked like new. It even still had the hatch marks inside the cylinders from manufacture.
You will go through several clutches before getting to 100,000 miles, and other parts. But the engine is good.
[edit] Oh, I thought I was in the Sportster forum. But, I guess the post is still somewhat relevant about the HD engine.

Biggest cause of failures on Harleys: The owner. People just love to fiddle with their bikes (me definitely included) and if anything is going to fail later on its what's been messed with.
The bikes you tend to see with the mega-miles on them are the stock ones.

A lot depends on your driving habits. I have an '06 FXD (88) w/ 131 K Mi. on it, and it uses less than 3 oz. of oil between changes.
The only thing I've done to the engine is change the cam chain tentioners @ 90K as a preventive measure, and they didn't really need it.
My belt, primary chain and tentioner, and clutch are all O.E.
I mainly drive freeway speeds, 75-85ish MPH, not much stop-n-go stuff. Normal RPM run range 2500 - 4500, and it's never seen the RPM limiter.

This is the only forum that I frequent that doesn't archive threads. On other forums after a set period of time the thread is archived and can't be posted in any longer; you can still read them and find them with a search, but you can't turn them in to zombie threads...
