The seat cover on my bike is a SecondLook piece. I ordered it specifically with the red and black color scheme. The foam on my seat was still decent so I just got out my electric stapler and covered it myself. It's not at all hard though it is a bit time consuming as you have to be patient to get it right.
I would think twice about Corbin as they have a really bad rep for customer service and a couple of people I know didn't think much of the comfort.
second look makes awesome seat covers. if yours is thrashed, pick up one on ebay, and you can send it to a guy in fresno california (RENN UPHOLSTERY) AND ASK FOR CRAIG RENN. he has done all of my seats in the past. does awesome work!! highly recommended. tell craig that jason hooked you up. you wont be disappointed!!
