At age 82 I was not surprise to suddenly get a lower backache. I have been riding my Burgman 650 for a number of years. When I first bought it I added a Utopia backrest and a gel seat cushion. The ride seemed very comfortable at the time. The suspension on a Burg is not the softest but other features more then out weigh the ride characteristics. I usually go on 150 mile rides with a group twice a week all year round. At first I tried to think what caused the backache. Kidney stones, a pinched nerve in my lower spine, arthritis or a combination of these things. My doc gave me an Rx for a muscle relaxer. After taking one pill last night half the pain is gone. I'll know in a week if it was just a strained muscle.
