It is very simple. They give you money (the full price of the bike) in hand and then they can take it for a ride. And do not take any cheques. That will eliminate any wishers, tire kickers and joy riders. That way you will also know that you are dealing with serious buyers only. I would suggest not to rely on any insurance, as the moment shit hits the fan they will look for any excuses not to pay. Good luck with the sale
