Sold my 2011 GS, kept my Seth Laam seat which was built for my 170 lb. weight. It was comfortable enough for a 50CC IBA ride which included a 1500+ mile day. Current price for a Laam seat built on your seat is $349 plus shipping each way to/from California as well as the wait time. I am asking $300 including shipping to Conus and I do not need your old seat.
