Wider touring seat. I don't have the seat with me right now so I'm not sure of the brand, but it is well padded and much more comfortable than the factory brick that came on the custom. Seat is in good shape, no tears or anything.
I also have the factory seat for $50 if anyone wants it. I'm turning the bike into a bobber and making my own spring seat for it so I no longer need these. I would also trade for an exhaust that fits the bike.
