Stock seats I have seen advertised are about $400. That's the same price Sargent will charge to re-do mine.
This is not riding season here for me. It's 92 today in Florida. Down here I ride in the winter months. I have a friend who sometimes trailers my bike to North Carolina. I drive up and take it into the mountains. It's an 800-mile ride and goes through Hotlanta to get there from here. That's not my thing.
