I just bought one of the zx14 seats for my 2008. So far, I like it. It is slightly more firm and close to 1 inch lower. More importantly the shape does not lock a person into place like the stock seat. The shape of the sides makes it easier to deal with at stoplights. The shroud the zx14 seat comes with will not fit without removing the rack. The seat does not fit until the center brackets are switched, btu it takes 30 seconds to remove them. Otherwise, the seat pans are the same.
