The new Road Kings come with Heritage style bars now. That's a big improvement over earlier years as those were too short for most. Although an improvement, I plan on going to WO 515s which are 10" bars, anyone install these on a newer King yet? Just wondered if I can get by without changing the clutch and brake lines etc. I did my Limited with ABS, worked good but still had the dealer put it on the Digital Tech later for safety. At least this bike has a cable clutch and no stinkin hydraulic one. Don't mind puttin wire extensions on, but changing the brake and clutch are a PITA. I've done several.

 

I did 502's 12.5" on my 2014 King, for sure the brake line had to be replaced along with switch wire extensions. the Throttle is fine, lots of slack there and I rode for a few days with the stock clutch cable before I changed it out. You might be able to get by with the stock clutch and 10" Chubby's but be sure so you don't stress and brake the cable out on the road.

 

Yea I agree tje 12s would be pushing it. I had put 12.5s on a couple bikes. 2.5 inches can make a big difference I'm hoping.
