Nobody -- or at least very few -- go to a dealer to buy a used bike. Most know they can get a better deal elsewhere. Dealers that take used bikes in on trade often sell them to a wholesaler. The guy trading the bike in wants to get some money, the dealer wants to make some money, the wholesaler wants to make some money, etc. There isn't enough value in a bike with 66K miles for all of those entities to make enough to pay their bills.
And that leads to another place to sell your bike... contact the wholesalers. Google "motorcycle wholesaler". That said, I will pretty much guarantee that you won't like the amount that is offered. They want to make money, have a very good idea of what they can sell the bike for, and have the added expense of having to ship the bike where they think it can be sold.
