I asked more specific question related to this issue on the modification sub-forum, but as back pain is a very common problem it may be useful to discuss here. should be discussed on general. I have an svx650 Yamaha cruizer, and after riding it my lower back hurts. I am certain this is because of the riding position - arms and legs stretched forward, - which results in flexion of the lower back. Has anyone else had this problem? What was the solution? I hope there is one, as I enjoy riding a lot and wouldn't like to give it up because of back issue. I am thinking of getting a back support and also reducing the angle of my handlebar, thus making the grips a little closer to my body.
