New for 2017, the Road King Special turned the Road King into a blacked-out hot-rod bagger: no windshield, mini-ape bars, stretched saddlebags, black exhaust and trim, and a 19 in front / 18 in rear Turbine wheel set with lower suspension. It used the same Milwaukee-Eight 107 and Showa suspension as the standard Road King.
