It was on a v star 650 had a gel insert. I took out the gel and put in one of those inflatable horseshoe neck pillows with just a LITTLE air in it, put 4,000 miles on it last summer on my RSV. Best ride yet. I packed an extra blow up pillow but the $2.00 thing is going strong. The air really eliminates pressure points. My bony ass has no padding. I throw it on when needed for longer rides, "fitz-all" bikes.
