I purchased a detachable tour pack for my streetglide special... so maybe I should put it on and then either measure or find someone to swap seats with.
Looking to have a wider rear seat when tour pack is on but had planned on picking one up second hand since I most likely will only have it on bike when Misses is riding.
I have a Mustang touring seat from the 08-13 touring line on my '14 Limited. Yes there are some differences in the seats. If you check the Harley seats they do not list the '13 and earlier seats to fit the '14. The space between the tourpak and seat is longer on the '14s and the stock '14 passenger seat is wider. I noticed it right away when I mounted the seat on my '14. the mounting brackets etc are the same, it's the length and width of the seat that is bigger on the '14s. I found it interesting that you asked for 1st hand knowledge on this issue. That did not stop other from sayin "what they heard or maybe" I figured you could use what you actually asked for and not guesses.
I have my Harley low reach seat 12-FLHTK And it fits just fine on my 14-FLHTK, maybe just a little shorter at the tour pack but nothing to be concerned about.
Anyone try a Zeppelin seat yet? They are pretty big all around and fit tight on my RKC with a tour-pak….dealers says no! I think he is wrong and nothing like first hand info.
