How do you feel about your children getting into motorcycles

One of my young ones who is in her teens goes out to the shed with another young one from her school to talk their own stuff in private, girl gossip. Although there is very little space in the garage they manage to work their way in without knocking stuff over and sit on the only possible places to sit on my SD250 and my GT550, (the SD400 is actually in the upstairs bed room at the moment). Easy for them to do this as they are both skinny now, my young one lost a lot of weight since she started cycling to school instead of bussing and been driven and she gets to keep the bus fare as a reward. She is starting to take an interest in the bikes and asking questions, this is partly good as it ties into her science in school in a small way. I know there is always a risk with motorbikes, but I see myself as fairly unique in that I have no desire to speed, I'm a very easy rider, also I have a good sixth sense about danger. Even if I had a bike accident now, I lived out my youth with out injuries. I am wondering will I be doing right or wrong if I feed her interest in motorcycles. Her mother is a disaster when it comes to road skills, stops on roundabouts, tries to drive up one way streets, is nearly always in the wrong gear, rides the clutch, forgets to turn on the lights, hopeless at reversing and parking. I am worried that if my young one takes after her mother on the road I may regret it if I introduce her further to bikes. Aside from the bikes, the family home, the clutter and the pets, the family is all I have and they have cost me a lot along the way. Have any of you guy ever had doubts about introducing your kids to bikes ?
