Touring Street Glide Special FLHXS (MY2021)

Factory Custom, Highway Ready

The Machine's Character

At the center sits the Milwaukee-Eight 114, an oil-cooled 45° V-twin displacing 1868 cc and pushing 118 lb-ft to the rear wheel through a six-speed box. Peak output reads 93 hp, but the figure that shapes the ride is the low-end shove that carries all 827 lb off a stoplight without drama. The BOOM! Box GTS runs infotainment and audio, Daymaker LED lighting owns the dark, and the batwing fairing gives it that unmistakable slammed profile. This is Harley's factory-custom hot rod dressed for the interstate, built around presence as much as capability.

On the road it plays to high-speed stability, tracking straight and settled once the speedometer climbs. Build quality feels solid and the platform has proven reliable enough to trust across long seasons. It suits the rider who wants sound and presence first, mile-eating second, and who values the deepest aftermarket catalog in motorcycling. The honest caveat: the stock rear shocks run firm over broken pavement, the short windshield throws buffeting at taller riders, and the rear cylinder bakes your right leg in slow traffic. Know that going in and the character earns its keep.

The Voice of Experience

Portrait of NastyNils

The test ride

Thumb the starter and the V-twin settles into that deep, uneven idle you feel through the floorboards before you really hear it. Roll away and the sound is the headline, a big bass note that fills the fairing pocket at cruising speed. The engine stays reasonably smooth for a big twin, though you never forget there's a lot of metal working underneath you. Settle in and the ergonomics are pure long-haul lounge, feet forward, hands set wide, back upright. Two sensations reach you fast on a warm day. Heat rises off the rear cylinder onto your right shin at a standstill, and if you're tall the short screen pushes air straight at your helmet. At highway pace it feels planted and unbothered, exactly where a bagger wants to live.

The Truth on the Street

These notes aren't from a test bike of mine. They're what settles out after years of catching what Street Glide Special owners tell me: talk at the gas pump, riders I meet at club nights, and the messages that land in my inbox. The same picture keeps forming, a short list of things owners back with conviction and a matching list of gripes.

What owners keep praising

Two things carry the praise. Riders lean on the big twin's low-end pull, the kind that clears a highway pass without a downshift and comes with that unmistakable exhaust growl. Then comfort: a cushioned seat, floorboards with space to move your feet, and an upright stance owners credit for full days in the saddle. Many also single out the sound system, which stays clean and loud enough to cut through wind at speed.

The gripes that keep surfacing

The gripes cluster just as tightly, all around comfort. Owners describe engine heat cooking the right leg once traffic slows on a warm day. They call out a stiff rear that jars over rough pavement and expansion joints. And taller riders say the stock windshield throws air straight at their heads, leaving them fatigued on a long stretch.

Known issues

  • Engine heat discomfort in slow traffic

    Many owners report excessive heat from the rear cylinder onto the right leg during low-speed riding or idling, especially in warm weather.

  • Stiff rear suspension impacting ride quality

    The stock emulsion shocks feel underdamped and harsh over road imperfections, leading to a jarring ride for rider and passenger.

  • Wind buffeting from batwing fairing

    The short stock windshield creates significant head buffeting for taller riders, causing noise and fatigue on extended highway trips.

  • Intermittent electrical glitches

The Long-Haul Verdict

Forget spec-sheet bragging. Here's who the Touring Street Glide Special FLHXS is actually built for.

Best cruiser for Sturgis?

If the ride is about sound, presence, and rolling into Daytona or Sturgis looking the part, this bike was built for you. The character and the catalog deliver exactly the statement you're after.

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

Best touring motorcycle for long distance?

You'll appreciate the stability and the lounge seating on big interstate days. Just budget for a taller screen and a rear-shock upgrade before you load two-up for Beartooth or Going-to-the-Sun.

Best motorcycle for Highway 1?

You can string together Blue Ridge or Highway 1 days on it, but remember you're steering 827 lb of bagger. It rewards a relaxed pace and presence over quick, flickable back-road work.

Alternatives to the Harley-Davidson Touring Street Glide Special FLHXS

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 Street Glide Special FLHXS. “cheaper/pricier” is what that bike costs second-hand, not how worn it is.
