I have been sitting on a Corbin seat for about 135,000 miles now. I am very happy with the quality of their seats and will continue to use their products on all of my future bikes. A few years ago, I ordered one for my Kawasaki ZX14. When I took it out of the box, I immediately knew I didn't like the texture and wanted to return it. After some rather frustrating time on the phone, they agreed to take it back and recover it. They even arranged for UPS to stop by my house and pick it up. Read the small print on the receipt. It reads "UNDER NO CIRCUMSTANCES WILL CASH OR CREDIT REFUNDS BE OFFERED". I took my Commando down to their factory in Hollister to have it custom fitted. I met Mike Corbin personally. He's a rather pleasant fellow. They gave me a tour of the factory. It's a busy place. The factory is HUGE! If I remember right, they ship around 100 seats out daily and have about 1800 seat molds for various bikes. If they don't have a mold for your fastback, they will make one from scratch. That is if you can get them the bike. I watched them make a seat from scratch, start to finish, for a custom sportster. The guys there are very proficient at what they do. It's very impressive to watch the process.
