I received my Corbin a few days ago. Normally I ride down to have these fitted to the bike, but I was impatient and ordered this one online. I chose the same materials that are in their demo seat, with carbon fiber leather for the seating surface, and asphalt for the sides. I also included the same red welt. When I first tried to put it on, it was quite tight and it didn't look like it was going to fit. But with a bunch of pushing, smacking, and swearing, I was able to get it in place to line up the rear seat bolt holes. I was careful not to crossthread them when getting them back in, and now all is well. Here are some pics: Full resolution pictures are available up in this gallery.
