I decided to drive down to Hollister today and get a custom made Corbin seat. I got down there by 9:30 AM and they asked me a few questions and went right to work. They molded and placed the seat foam on the bike and shaved some off and checked it on the bike again and shaved some more and back and forth until it was just right. Then they had me take a ride on the bike with the new seat before they upholstered it. I chose the basket weave top with the asphalt sides and I had them embroider the Corbin logo in red. I was out of there before noon. The fit and finish is really nice and I'm glad I went there and had them fit it to my bike instead of just ordering one over the phone and taking what I got, because I saw how many times the seat was placed on my bike and then a little taken off here or there before it fit like a glove. I haven't been on a long ride since I got it home, only to the next town's hardware store, but this weekend I will give it the test. Below is a photo of the seat on my SM 610.
