I think a lot of Harley's future problem will be generational. Not too many post-Boomers and later generations seem all that interested in Harleys. Just my anecdotal observation. I certainly haven't done any research on it. Just looking at who's riding what.
over-priced,under-reliable.
I don't know about that. I have an 11 year old who's counting the days until she's 16 and can ride a Harley of her own. I see lots and lots of riders in their late 20's early 30's these days. Much younger than that, and you probably can't afford one.
