This is probably a repost but I'm looking to get a different passenger seat. My question is which is the most comfortable aftermarket seat out there? I was thinking Corbin but I'm not sure.

 

Are you looking for a passenger seat or for a replacement riders seat? If you are looking at an actual aftermarket passenger seat, buy a gold wing. Sportbikes are useless with anything on the back excpet if your cruising the local strip, even if she (your passenger) is really beautiful. These are not meant for 2 up anything, the CG gets so out of line with someone, even at 100lbs and motionless, that the bike is too unstable for agressive riding.If your passenger is getting that much saddle time that they complain about the seat they should be riding their own bike.

Now if you are looking for a riders seat Corbin is thought to be one of the best. Personally I have found the factory seats to be the best on most sporto's. Yes I have tried to change them and never found one I liked.
