Hi Mully. The Pillion seat is a big improvement over the standard bar stool pad Triumph provides. First I had a custom auto/motorcycle fab shop expand the pillion seat pan by about 7 inches to the width and about 3 inches rearward. Then I had a local upholstery shop re-pad and cover it. It was better than the barstool pad, but still not very comfortable. Then I met Rick Mayer at a motorcycle rally in John Day, OR. He told me about how he uses orthopedic foam in his seats and shapes it to your butt and riding position. So the wife and I made an appointment at his shop in Anderson, California and went over there while on a vacation and had Rick and his crew custom build what you see in those pictures above. Very nice work and very affordable.
The pictures below are from the first attempt done locally here in the Boise area. The pan expansion was the key to the good work done later by Rick Mayer.
