No, those numbers are totally incorrect. There is a similar site called Howmanyleft.com, they also have incorrect figures, it does state in their disclaimer the figures are known to be incorrect when it comes to older bikes.
As an example, I personally have 289 'regular' individual buyers of 400/4 parts from my eBay page and so far this year, I've had another 32 'new' buyers of 400/4 parts. Obviously, these figures don't include owners who buy from me direct, ie, forum members, Facebook members etc either.
