I got my 09 Deluxe on the 25th of September......250 miles into ownership, my ass in no uncertain terms, let me know stock wasn't going to cut it... I bought the 15" Vintage Sport Solo With Driver Backrest from Mustang...It keeps the lines of the bike clean and makes my ass happy, although a bit pricey...I also picked up the 11" matching biatch seat, and now her ass is doing the happy dance as well...It's darn comfy, and if after 500 miles you want it a little softer, you can send it back to Mustang and they'll soften it up for you for free...I ordered on a Tuesday and it was at my door on Friday and only $1 to ship...
