HD is not known for having unusually good reliability and build quality. In fact, most people consider them below average. I suspect the issue is not that their bikes last so long per se, but rather that so many people buy them, don't ride them much and then decide to stop riding motorcycles. There is probably a fairly high amount of purchases that go to middle-aged dudes looking for a new hobby that give it up pretty quickly.
