Then there's a few of us who like to buy new. I have always liked to buy new and then do the breakin the way I want to do it, and then I'm also the one whose done the maintenance etc. I don't mind the depreciation "hit" as I tend to keep things and not trade in or upgrade every 2-3 years, more like 6-8 for cars/trucks and 4-5 or longer for bikes. My wife on the other hand goes through bikes like I go through shirts.
There's enough riders out there willing to buy new to sell out however many bikes they decide to make, IMO. That's good news for you second hand guys.
