No its not you, its the buyers.
I have sold 4 bikes in the last 7 years (all 4 years old or less) and can tell you all of the people wanting to buy, wanted it for at least 25% off what I was asking, which was book value and was less than what a dealer was selling for. I'm usually not firm with asking price and I can negotiate on asking price, but when they saw the condition of the bikes (mint) usually the first question was, 'will you take THIS'? (asking price less 25%).
Then for me its like 'huh', 'don't you want to get into specifics'? When one buys something its customary to talk about the article in question, like; are you the original owner, how long have you owned it, how many km, has it been down, have you ever tracked it, can I get a test ride, etcetera. Finally if the buyer is interested, the last question is price, not the first question.
It was consistent and unbelievable at the same time. Its like they were a clone of each other, only with different faces. I'm still scratching my head. I have sold many items (cars, etc.) over the years but I have never seen anything like it except with selling of bikes (they were sport bikes). I have no theory as to why this would be, other than they were immature (25 or younger) and likely have heard of a bargain that a friend got and figure they are entitled to one too.
