I agree with all the answers so far that have been given. One thing I did was to get on a wide road, with no other cars around, and told the wife while I was going, at 35mph, that I would go as straight as possible and that she should lean way out and look at the bottom of the back tire. When she did we swerved pretty good. I was ready for it, she wasn't. Scared her and when she asked why "I" turned the bike I told her she did that. She has a good amount of control as a passenger. She always thought I wanted her to sit still just because it bugged me. Once she learned this, she has become the best passenger I have ever ridden with.
