Just installed the Road King handlebars on my '11 Deluxe. The procedure was pretty straight forward and having a service manual is a must. The only cables/lines that needed to be changed were the throttle/idle cable and the front ABS brake line. This was easily solved using Magnum Shield BYO throttle/idle cable kits and and I used an ABS brake line from a '11 Heritage. The wiring had plenty of slack so splicing or adding extensions wasn't necessary and the OEM clutch cable didn't need to be changed either. The little man on the bike supervised the evolution.
