I've heard of the Corbin break-in before, too. Didn't really notice it on mine though. Some will say it takes ~300 miles for your butt to get used to it more than it takes ~300 miles for the seat to break in.
I picked up mine used from a board member when he decided the Bandit wasn't what he wanted. The seat only had ~60 miles on though, so any "break in" wasn't complete. I was a little worried at first that I wasn't going to like it because it IS firmer than the OEM seat, but after about a half hour I was in love with it. I did get a pretty good deal on the seat & backrest - paid less than the price of a new Corrbin for both the seat & backrest and at only 60 miles, it was practically new. Another plus was the guy lived about 60 miles away, so I just arranged to meet him and pick the seat up live, so I didn't even have to wait for shipping.
