Well I dont go overboard on speeding most of the time, if I am in my car, I am normally 10-15 over, unless I am in town. The only time that I speed unsafely is on my bike. But I am getting rid of my bike. I recently lost a good friend to a bike wreck where speeds i excess of 160mph were involved.
If you speed unsafely on your bike then the best thing to do is to get rid of it. I'm glad you're making a smarter decision before something bad happens.
