I currently own a 2009 fireboat xb12r and my only complaint is the stock seat. The thing is rock hard and those 3+ hour rides are getting very uncomfortable. I found a Corbin seat online that I really like, however, the website says it is for a 2004-2005 model. I called my local harley dealer to see if the part number for the stock seats on those models are the same and they told me they are not, which makes me believe the seat might not fit. However, the guys at Corbin gave me a picture to compare the underside of the seat and the arrangement of parts under the seat on an 05 model and said if they look similar (they look identical) then the seat should fit. I also found an old thread that claims the firebolt corbin seat fits all later models. Before I commit and spend the money, I wanted to see if anyone here knows for certain if the 04-05 firebolt corbin seat will fit later models as well?
