Like a few of the other inmates say trust is a big issue and getting to know the person who wants to ride your bike would take some time. Best thing to do is start the communication. I have a Honda Dominator I'm happy to let visitors use so contact me if you are ever in my neck of the woods.
Loaning out my GS1200A is, well a different issue becase it's not just a bike it's an extension me, part of my personality
. In saying this I'm not ruling it out but I'd need to know your expereince, where you would want to ride, a bond in cash to cover the insurance excess and agreed servicing pre and post the ride. And if this was topped off by a counter offer things could probably be worked through.
