If you spend the $ , many custom companies make custom seats for your ride. I have a Mustang seat on mine & it is the most comfortable seat that you ever put your "skinney" butt on. Most custom seat cos. also make upholstered pads also! You would probably have to look in a catalog for them.

P.S. I will recommend "Mustang" products. When living in another state , I used to build custom bikes & altho there are many good manufactures , I have NEVER had a problem with a Mustang seat & I'm talking alot of bikes!
