I usually am pretty cautious about who I let even sit on my bike, I have met people who really dont care who they let ride theirs and I cant really understand that. Last year I was riding with my friends and we were gassing up at a local station when a car pulled up with some girls we knew in it. They liked our bikes (my '07 red FZ and a Ninja and a R6) and wanted us to let them RIDE our bikes. We all said no way but we would give them a ride if they wanted, but they got really mad and said we were a$$holes and we were sexist and some other things. Will you guys let other people ride your bikes? I have let my best friend and my brother ride mine, but I was riding theirs at the same time, but thats about the only people I would trust.
