I have installed a kicker on a Road King.I seriously doubt you're gonna like it if you do it,the exhaust has to be heavily modified & the bags get in the way,couple that with the fact that it doesn't look like it belongs there (as opposed to the Knucks,Pans & Shovels) it just sticks out like a diamond in a pigs ass,very obtrusive & goofy looking.Just my opinion,but I would spend the considerable money it's gonna cost you on something else.
