Most likely true. Just look at all the HDs for sale by owners in Craig's List!
A lot of the flooding of the market with used harleys started back in the early '80s with the shift in sales techniques & the incredible influence that bullshit cable TV network "motorcycle clown shows" had on who & why guys bought harleys or had them built for them at unbelievable cost by both legitimate & bullshit artist "custom chopper builders".
There were many years when every harley that arrived at a dealer's was already sold & you had to buy $3,000 worth of Chinese accessories before you could even get on the list to buy one.
Then, after the divorced guy, who had just spent $30,000 to $80,000 on a "factory custom" or a "master builder" custom "chopper" (on a SoftTail frame, of course) had spent a season or two on it & spent a fortune on Just For Men, Viagra & Officially Approved Chinese Motorclothes, he found out he STILL couldn't get laid by 20 year old girls plus the bike hurt his back & the Oxycodone wasn't working any more & he got caught in the rain once & got wet, poor baby. So the bike sits for a year & then ends up on Craig's List at a ridiculous price he thinks somebody will pay for a bike HE thinks is "rare" or "one of a kind".
I've watched this whole thing happen day by day for over thirty years & laughed since the late '70s & just kept on riding on what I built in my own garage never darkening a dealer's door since about '81 or '82 when I got thoroughly disgusted with the Motor Company as a company especially after they started shutting down small bike shops that had supported them for years with ridiculous infringement law suits. I stopped caring much at all after the end of the shovelhead ('84 1/2). I've just sat back & been an observer of the clown show (or Pirate Show as some others have called it).
Don't get me wrong. I still love harleys & still ride a kick only I built myself (the last of three). I also kind of laugh at how much pure nasty hatred there seems to be from some of the RE people here at both the bikes & the riders. Why? There is something I like about every single motorcycle on the planet if I look at it long enough. There are many that I can just sit and stare at & marvel at for hours, but not necessarily ever want to own one. Why the hatred of harleys. Is there some "If it's American it can't be any good" thing going on here? Have they been beat up by pirates?
Harley's still selling bikes. Lots of them. 110 years? They're doing something right (I guess) even though I think they're WAY overpriced & I don't like their advertising or their overbearing attitude. Or the huge % of the bike that's Chinese. Or the fact that ALL the accessories are Chinese.
