Road King Special FLHRXS (2021): "A Harley-Davidson Icon Transformed by Custom Bagger Style and Milwaukee-Eight 114 Power"
Total Motorcycle's own confirmed dealer copy sums up this trim's genuine identity directly: "a Harley-Davidson icon is transformed by custom bagger style and Milwaukee-Eight 114 power... a custom bagger with top-of-the-line power and a commanding presence." That same confirmed guide details a genuine, tangible upgrade for this specific model year: "the Road King Special model is now equipped with a Daymaker LED headlamp, replacing the previous dual-halogen headlamp. The LED Daymaker headlamp pushes out an impressive punch with a bright-white beam that lights up the road and makes the motorcycle more conspicuous in daytime," alongside a new tank medallion based on the Bar & Shield logo.
Power comes from the Milwaukee-Eight 114, a rubber-mounted, counter-balanced V-twin displacing 114 cubic inches, delivering a claimed 118 lb-ft of torque at 3,250 rpm — Total Motorcycle's own confirmed technical account describes exactly why this specific engine outperforms the standard Road King's 107: "four valve cylinder heads (two exhaust and two intake valves per head, eight total); improved airflow through the engine contributes to power output. Dual spark plugs for more complete combustion of the air/fuel charge and maximized power and efficiency. Single camshaft reduces mechanical noise so a richer exhaust tone can predominate. Advanced cylinder head design, dual knock sensors, and precision cooling allow a higher compression ratio" than the base 107.
That same confirmed guide details the genuine styling distinction built specifically into this Special trim: "low profile engine guard: designed to emphasize the slammed, low lines of the Street Glide Special, this 1.25-inch diameter engine guard mounts 11 inches lower than the standard Touring engine guard and features a slightly forward sweep that provides plenty of room around the brake and shift levers" — real, functional hardware layered onto the classic Road King silhouette.
Dennis Kirk's own confirmed parts reference lists 130/60B-19 front and 180/55B-18 rear tires, a 49mm fork, a non-sealed drive chain, and a 140-tooth/24mm drive belt — genuinely the same running gear shared with the Road Glide covered elsewhere in this catalog, both riding on the Milwaukee-Eight 114. This Special trim, sitting above the standard Road King FLHR's Milwaukee-Eight 107, represents the range-topping factory bagger configuration within Harley's 2021 Road King lineup.
This factory service manual covers the procedures, torque specs, and diagrams needed to keep a 2021 Road King Special FLHRXS running the way it was built to.
