The only 'correct' answer is: I don't know. But with that being said I've sold several motorcycles and never allowed a test drive. I did on one occasion take the prospective buyer for a test ride. Most folks (hopefully) are knowledgeable, know what they want and have checked it out and maybe done a test ride at a dealer of a similar model. So IMO the appearance of the vehicle, maintenance records, accessories and of course the price are the determinant factors.
