....I also just put the same Mustang seat on my 2010 Vulcan Classic. I'm 5'8", 175 lbs., and the seat actually set me back (into the rear support wall of the seat) just a tad, and ..maybe... 1/2" or so higher, but nothing that I would describe as a "riding on, instead of in" scenario. I spent some time with this set-up without any unusual discomfort....so next I installed a set of Gen-Mar 1" risers, which were easy to put on...unbolt the top cap...lower the bars down...slip the Gen-Mars under the bar...replace top cap with the supplied bolts, and adjust bars to height. The Gen-Mars were "just enough" to put the bars just a smidge closer, and up just enough so as to not feel like it was a huge adjustment, but very nice....along with the Mustang..the fit is very nice. I will agree...the stock seat was abysmal....I'm still going to send it to Spencer's for a mod though..just for the heck of it. You will love the Mustang...depending on your size...you might want to look at the 1" Gen-Mar risers...nice quality, and easy to install.
