Does anyone have any recommendations for non-slip seat cover materials? I had a very painful mishap today. Some myopic moron in a tin-top pulled out on me forcing me into a rather abrupt stop. This caused my pillion to slide into me, pushing me into the tank cover and crushing my b***ocks. I did just manage to get the side stand down without dropping the bike, but it was several minutes before I was able to ride off again. SWMBO said she would feel much more comfortable if she didn't slide forwards under heavy braking. Any Ideas?
