Blacked-Out Bagger, Pure Attitude
The Road King Special builds its whole personality around the Milwaukee-Eight 107, a 1,745 cc air/oil-cooled 45-degree V-twin pushing 89 hp and a thick 111 lb-ft at just 3,250 rpm. Harley kept the styling dark and deliberate: blacked-out metal, a shot of chrome to frame the engine, mini-ape bars, floorboards, and stretched saddlebags. There's no fairing and no infotainment screen in the way. What you get instead is stance and presence, a bagger cut down to its hot-rod essentials, with belt final drive and a six-speed box handling the long-legged cruising.
On the road it feels planted and unhurried. At 820 lb (372 kg) wet the mass is real, but the low center of gravity settles it once you're rolling, and high-speed stability is genuinely a strong suit out on open highway. ABS comes standard. This bike is for the rider who wants character and metal over lightness, someone who cares how it looks at every glance and how it sounds under load. The honest caveat: it's heavy in parking lots and tight turns, and early 107 engines had oil-system trouble worth checking before you buy.

Safety
Thumb the starter and the 107 settles into that familiar Harley cadence, a deep, uneven pulse you feel through the floorboards and the seat before you've moved an inch. Roll on and the vibration stays present but metered, alive without buzzing your hands numb. The mini-ape bars put your arms up and wide, the floorboards let you move your feet around on a long day, and the low 27.4 in (696 mm) seat means both boots land flat at a stop. Build quality reads well up close; the switchgear and finish feel solid under your fingers. At a steady highway clip it hunkers down and tracks straight, the kind of bike that shrinks the miles once the speedo climbs. It asks for respect at walking pace, then pays you back the moment the road opens up.
What follows isn't my own test ride. It's the read I've built over years of listening to riders who put real miles on these bikes: talk trackside, owners comparing notes at club get-togethers, and the steady run of emails and messages that reach me directly. For the Road King Special the picture holds together. The engine wins people over, and the grumbling clusters around how it rides on rough roads and at slow speeds.
Two things come up most. Owners keep flagging how willingly it changes direction for a machine this size, and they talk up the Milwaukee-Eight 107 underneath them. On the engine they describe torque that's there right off idle and hauls hard from low revs, and several note how much calmer it feels at a standstill than the Twin Cam it replaced.
The reservations gather around ride quality. Over broken pavement, owners say the rear suspension feels short on travel and lets the rough stuff reach them. The bulk draws comment too, asking real effort at parking speed and in slow maneuvers. A few also bring up buffeting off the stock windshield, with taller riders the most likely to want a different one.
Oil cooler line detachment (Recall 17V-333)
The oil cooler line may detach, causing an oil leak that could lead to loss of traction or control. This recall affects 2017 Road King Special models.
Early M8 oil pump sumping and oil starvation
Some early Milwaukee-Eight 107 engines suffer from oil pump sumping, leading to oil starvation and potential engine damage. This issue is more common on pre-mid-2019 production.

Forget spec-sheet bragging. Here's who the Touring Road King Special FLHRXS is actually built for.
If Sturgis and Daytona are on your calendar every year, this is your bike. The sound, the stance, and the brand weight are exactly what you ride for, and it delivers all three.
Made for A1A — Florida Atlantic Coast · Black Hills / Sturgis Rally Hub · Daytona Main Street / Bike Week
You love classic style and unhurried miles through small towns. The look and character fit you well; just know this is a full-size bagger with real mass, not a light modern classic.
Made for Acadia National Park · Austin / Handbuilt Motorcycle Show · Blue Ridge Parkway
It'll eat interstate miles and stays rock-steady loaded up. With no fairing and a 6.0 gal (22.7 L) tank, though, plan your weather and fuel stops on the biggest days.
Made for Beartooth Highway · Blue Ridge Parkway · Going-to-the-Sun Road
If this one isn't quite the fit, these are the bikes worth riding back-to-back against it.
Any price note compares both bikes at the same age — the youngest age both have on the used market — against this Harley-Davidson Touring Road King Special FLHRXS. “cheaper/pricier” is what that bike costs second-hand, not how worn it is.
