Made the switch on my '10 RKC from the factory bars to the "Heritage" style last night. Took about 1.5 hrs to do complete swap. Hardest part was getting the throttle by wire loom out of the stock bars. The snap module got wedged in the dimpled area and it took about 15 minutes to get it unstuck. What a pain in the butt that was. I was afraid that I was going to need to order up a new section. Finally got it out, and the rest went well. Even managed to save the grip and reuse it. Bought a Progressive drop in lowering kit, but need to pick up a socket for the tube caps, so will need to tear the front end totally down for that. Couldn't wait to try out the bars though. Will ride it to work tomorrow and see how it feels on the road. Doesn't look as cool as ape hangers, but feels better than the originals.
