It is 3 miles... big whoop, my wife felt the same way about seeing what others have done to themselves on a bike but all I did was drive totally different for her when she rides with me because I know when she isn't on the bike I can get on it whenever I want to take off hard. Take off's are extremely slow (which is a pain killer) and I have told her if she is uncomfortable just squeeze me harder and I will back off. Problem fixed, if she is afraid just because you have a CBR and not a Harley that is dumb. I mean come on a bike is a bike and you can wreck either one. Now I know you aren't going to be pulling wheelies with the harley but I doubt you were going to with the CBR so what is the difference. It is all in who the driver of the bike is, if you are one she can't trust to not do this shit then I can understand why she doesn't want to ride but if you don't she is crazy not to ride. She needs to trust you in order to enjoy it and by buying a harley she is no safer. Just my opinion.
