Touring Road King Special FLHRXS (MY2021)

The Blacked-Out American Classic

The Machine's Character

This is the touring platform stripped to its essentials. The Milwaukee-Eight 114 fills the frame with 1868 cc of air- and oil-cooled 45° V-twin, good for 93 hp and a thick 118 lb-ft, fed through a six-speed gearbox and a belt to the rear wheel. There's no fairing, no stereo, no screen full of menus. What you get instead is hard saddlebags, a commanding upright post, and blacked-out metal from the headlamp to the pipes. In a class that lives on stance and mechanical presence, this one plants its flag firmly on the old-school American bagger end of the room.

It rides like what it is: a heavy, low-slung mile-eater that trades agility for stability and substance. The low center of gravity and 64.0 in wheelbase keep it planted and confident once you're rolling, and the mechanical feel gives it a character that never turns sterile. It's built for the rider who wants the big-twin experience without the bulk of a full dresser. The honest caveat sits with the engine. Some Milwaukee-Eight 114 units have shown heavy oil consumption and early lifter noise, so a careful look at any bike's history is money well spent.

The Voice of Experience

Portrait of NastyNils

The test ride

Swing a leg over and the first thing that registers is how low it sits. At 27.4 in the seat drops you into the bike rather than perching you on top of it. Thumb the starter and the 45° twin settles into a lope you feel through the wide bars and the pegs, a pulse that stays this side of intrusive and speaks to you without wearing you down. Around town the 807 lb makes itself known at walking pace, but roll onto an on-ramp and the mass melts into the tarmac. Wind hits you square with no fairing to hide behind, and the arms-out stance leaves you sitting in command of the road, reading the surface through your hands and your backside. It's a machine that rewards a steady, unhurried rhythm.

A long, straight paved road stretches toward the horizon through agricultural fields in Vermont. Power lines and a mailbox are visible along the roadside. Lush green vegetation, cumulus clouds, good daylight conditions. The landscape is flat to gently rolling. Asphalt pavement appears to be in good condition. Rural American setting.

The Truth on the Street

This isn't pulled from a brochure. It's the sense that builds over years of listening to riders: talk at rallies and gas stops, conversations on club nights, and the notes that land in my inbox. On the Road King Special the pattern holds steady. The praise clusters around the look and the engine; the gripes stay few and familiar.

The look and the pull riders praise

Style leads every conversation. That stripped custom look, blacked out from headlamp to pipes with thin chrome accents and no fairing, reads to owners as the real thing and sets it apart. Close behind comes the big V-twin's low-end torque, enough to make passing and hills feel easy on a rumble riders enjoy. Some add that the deep, contoured seat carries them through long days without fatigue.

The gripes that surface with miles

The complaints run fewer and softer, but they persist. With no wind protection out front, owners feel fully exposed, and fatigue builds over long highway stretches. A handful aren't sold on the cable clutch, reading the move away from a hydraulic setup as less fitting for a touring bike. Others note the reduced cornering clearance once the pace quickens, where floorboards and bag guards drag sooner than they'd like.

Known issues

  • Milwaukee‑Eight engine oil consumption and lifter noise

    engineoccasional

    Some owners report excessive oil burning and premature lifter failure on M8 114 engines, possibly linked to oil pump or breather issues; severity varies.

  • ECM data port blocks aftermarket tuners

    The new ECM data port introduced in 2021 is incompatible with existing aftermarket EFI tuners, forcing owners to use the restricted Harley‑Davidson Screamin’ Eagle tuner or wait for updated third‑party solutions.

Forget spec-sheet bragging. Here's who the Touring Road King Special FLHRXS is actually built for.

Best cruiser for Sturgis?

If your year runs through Sturgis and Daytona and the badge matters as much as the ride, this lands right where you want it: real presence, the right voice, and a parts catalog with no bottom.

Made for A1A — Florida Atlantic Coast · Black Hills / Sturgis Rally Hub · Daytona Main Street / Bike Week

Best retro motorcycle for road trips?

For slow days on historic two-lanes it looks the part and sounds it too. Just know you're signing up for 807 lb, so it's more heavyweight classic than easy-going retro runabout.

Best touring motorcycle for long distance?

It's rock-steady at highway speed and swallows gear in the hard bags, but with no fairing and thin weather protection, loaded two-up over big country you'll work harder for comfort than a full dresser asks.

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.
