Softail Fat Boy Special FLSTFB (MY2010)

Slammed, Blacked-Out, Built Mean

The Machine's Character

The Fat Boy Special takes the lowest, meanest spot in Harley's Softail range and commits to it fully. Seat height sits at just 24.3 in, the front end is deliberately wide and heavy, and the whole bike wears a blacked-out, stripped-down finish that reads as factory custom without a single aftermarket part fitted. Underneath is the 1584 cc air-cooled 45-degree V-twin, tuned for 94 lb-ft and 66 hp, paired to a six-speed box and quiet belt drive. This is a machine built around stance and attitude first, and it never pretends otherwise.

On the road that low center of gravity does real work, settling all 730 lb (331 kg) into a planted, unhurried gait that flatters relaxed riding more than hurried inputs. Build quality is genuinely high, the kind that survives close inspection and years of weather, so this generation ages with dignity rather than cheapening. Be clear-eyed about the trade: 66 hp is modest muscle for the size, low-speed parking-lot work asks for respect, and some early 2011 bikes fell under a body control module recall for water intrusion that could stall the engine. Buy it for character, not urgency.

The Voice of Experience

Portrait of NastyNils

The test ride

Thumb the starter and the big V-twin drops into that loping, uneven idle you feel in your palms and boot soles a beat before it fully registers in your ears. The sound has real depth, and the vibration is metered so it talks to you at a stop and then smooths out as the revs climb, present but never punishing. You sit low and laid back, feet forward, looking over that broad front wheel, and the riding position tells you to slow your pulse down. Wind it up to highway speed and it holds a line with reassuring weight, tracking straight through open sweepers and staying composed when the surface turns rough. It feels dense, deliberate, and honest under you, a motorcycle that rewards a rider who is in no rush.

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

Over the years I've kept a running tally of what riders tell me about the Fat Boy Special: conversations in the pits, talk at club nights, owners I've caught up with along the way, and the questions readers send me directly. Boil it all down and the same picture returns. People buy this one for the styling and the effortless low-rev pull, and a small set of quirks comes up again and again.

The Look And The Low-Rev Pull

Two themes dominate the praise. Riders keep coming back to the fat, blacked-out custom stance that shows up straight from the factory, with no aftermarket parts required to earn it. Just as often they point to the tractable low-end grunt of the big twin, easy to meter through town and enough for a relaxed highway pass. The very low seat gets its own steady mention too, letting shorter riders and those with a short inseam flat-foot with room to spare.

The Quirks That Keep Surfacing

The recurring grumbles stay small and consistent. A strong side wind gets under those solid wheels and calls for a steadier grip at pace, though owners say experienced hands adjust fast. A few find the forward controls and floorboard placement leave them reaching on longer hauls. And the side stand sits awkwardly close to that left board, so dropping it takes a deliberate foot and a beat of care.

Known issues

  • Body Control Module (BCM) failure

    electricsoccasionalRecall

    On some early MY2011 Softail models (built June through October 2010), the body control module (BCM) case may not have been properly sealed, letting water intrude and cause the engine to stall — a stall in traffic risks a crash. Under the safety recall, dealers replace the BCM free of charge.

Best cruiser for Sturgis?

This is your bike without apology. The sound, the stance, and the Harley identity are exactly what you ride for, and it looks right rolling into Sturgis or down A1A with the pack.

Best retro motorcycle for road trips?

The style and unhurried rhythm suit your slow routes and historic main streets. Just know it rides heavy and low, so it rewards easy cruising over quick, flickable back-road play.

Best touring motorcycle for long distance?

Honest answer: it has the presence but not the kit for your kind of days. The 5.0 gal tank, low seat, and missing wind protection make big two-up national-park hauls a stretch.
