I don't think that is his point; that's not what Harley does, at all.
H-D markets themselves as a "lifestyle brand". You don't just buy a motorcycle and you're done. You are aggressively marketed toward for a bunch of different pieces of clothing, spare parts, co-branded partnerships with automobile companies, et cetera, ad nauseum. You are effectively buying into a subculture.
Furthermore, Harley-Davidson has been known to use almost identical sales tactics. IIRC and I can't find it now, but sometime last year a sales guidelines book was leaked that actually did things like put attractive models at gas stations to tell the prospective buyer "nice bike" or the like on their test rides.
