I have now had 3 Corbin seats. First one was on my CBR600F3 and it was great for me, but not great for the passenger as it looked like it had a fastback design to it, which basically took the rear position and made it look more like it was a cowl than a seat. On my TL1000R, I had the Corbin on the front seat and the stock seat for the back, since Corbin never did make a rear seat for it. The TL1000R seat really was miles better than the stock seat. I had many 400 mile days on that seat and since it gave room to move around, it worked for me even though it was very hard.
On the C14, I can't speak a whole lot to it yet since I just got it, but it does give you more room front and back to move, which I like. It also allows you to slide on the seat which the stock seat didn't do as the material was too "grippy". You do have a lower seat which was good for me as I can now touch better with my 29" inseam.
