your bike...your rules! only one other person has ever ridden my bike and that is my buddy that i have ridden with for years, i know him and his riding abilities and knew that he listened to me when i told him how powerful Lucy was and to take it slow, when we finished our ride (i was on his) he had the biggest grin on his face i have ever seen, he said he would love to own one but he knew he didn't have the self control to ride one of his own everyday...needless to say that scared me and he, nor anyone else, has been allowed on her since if i can't trust my best riding friend, i can't trust anyone who doesn't own one of their own and appreciate and respect it my response now is, "sorry, but i won't be responsible for your death" if they can't understand that, they don't understand what they were asking for in the first place
