I don't like the idea of riding someone else's bike or letting someone else ride mine. My bike is a part of me and I take that same attitude about someone else's bike. Obviously demoing or renting a bike may be different. OK... I did borrow my brother's Bonneville once, but that's different, I am his older brother and I needed a bike that weekend. My dealer is a very good shop, they test ride every bike they service. I trust them very much, but whenever I se Randal pull out of the parking lot on my bike I cringe a little. Its the same way with my car. It's just weird seing someone else driving it.
