When my wife and I were married I was without a bike for the first time since I was a teen. We had been married a couple of years, and every summer we would be out in the car and someone on a bike would cruise by and I would tell her I'm not going another year without one. Of course she would say sure dear. Well three years ago as soon as the weather warmed up I found myself a the local dealer and I ended up riding my new bike home. When my wife got home from work my new bike was in the driveway. I could see her cold look as she pulled in. After telling her that I hoped she would enjoy riding with me I let the subject drop. We went for a few rides together and she tolerated it for my sake, but I don't think she enjoyed it that much. Low and behold she calls me at work one day and tells me the next door neighbor is selling his bike and she wants it for her. You could have knocked me over with a feather. My wife was 55 years old and not only had never ridden a bike, but had never driven a stick shift. After checking out the bike, it would not work as it was an older Honda and too tall for her. She was very disapointed. So for her birthday I bought her a brand new Honda rebel. She signed right up for the motorcycle training at our local college, and after several days at the local downtown airport on sundays with no or little traffic, I continued her training myself untill the day came that I felt she was ready for the real thing. Now she rides with me whenever we get the chance, and she has rode as far as 100 miles with me on a few trips. It's sooo cool to be able to have her as a riding pal, but to answer your original question, I still worry about her going down. You can reduce the risk by picking your route to less traveled roads, and ride at times when traffic is lite but I will always have some concern, but I feel the same about my son who also has a busa and can ride circles around me!
