Harley-davidson Fat Boy
The Harley-davidson Fat Boy has a top speed of 175 km/h (estimated; note: electronically limited in some markets), produces 93 hp and weighs 317 kg. Motoryk rates it 7.8/10.
The Harley-Davidson Fat Boy was introduced in 1990 as part of the Softail family, featuring its iconic solid-disc wheels and wide, imposing stance that made it instantly recognizable. It gained massive cultural popularity after appearing in the 1991 film Terminator 2: Judgment Day, ridden by Arnold Schwarzenegger. Over the decades it has undergone several engine upgrades, moving from the Evolution to the Twin Cam and eventually the Milwaukee-Eight 114 engine in 2018, remaining one of Harley-Davidson's best-selling models.

What Buyers Should Know
Strong Resale Value
The Fat Boy consistently holds 70-80% of its value after 3 years, outperforming most cruiser competitors. Its iconic status and loyal fanbase keep used demand extremely high.
Watch the Cam Chain
2000-2017 Twin Cam models have a known cam chain tensioner wear issue that can cause costly engine damage if ignored. Always verify this has been inspected or upgraded before buying used.
Signature Solid Wheels
The Fat Boy's iconic solid disc wheels are unique in the production cruiser market and define its bold visual identity. However, they can make the bike feel slightly more susceptible to crosswinds at highway speeds.
Generations & Specs by Year
Original FLSTF debut, 1340cc Evolution V-twin, solid disc wheels, shotgun exhaust, iconic silver colorway.
"The bike that made posers into believers."
I put 22,000 miles on a '93 Fat Boy and that Evolution motor never once left me stranded — it just thumped along at 3,500 rpm like it had nowhere better to be, which is exactly the right attitude for this machine. Those solid disc wheels look like they were cast from a single piece of mythology, but they'll remind you they exist every time a crosswind hits the highway and the bars twitch in your hands. Forty-eight horsepower sounds embarrassing on paper until you feel 92 Newton-meters arrive at a lazy throttle twist and pull 295 kilograms down a two-lane like it weighs nothing. The low seat is genuinely confidence-building for shorter riders, but lean angle is a cruel joke — scrape the floorboards mid-corner and you'll remember this is a cruiser, not a canyon carver.
Pros
Cons
Twin Cam 88B engine replaces Evolution, rubber-mounted powertrain, updated frame and suspension components.
"Smoother, quieter, but the soul survived the upgrade."
The Twin Cam 88B's rubber mounting genuinely transformed this bike — vibration that used to numb your hands on highway stretches is tamed enough to ride 400 kilometers without stopping to shake your fingers back to life. That torque hits hard and low, exactly where you want it for lazy roll-ons through traffic, and the Fat Boy's wide, solid stance makes it feel planted in ways that inspire stupid confidence on sweeping bends. It's still 317 kilograms of slow-speed awkwardness in tight parking lots, and the suspension remains optimistically soft for anyone above 85 kilos or carrying a passenger. Braking is adequate rather than reassuring, and if you ride it hard into corners you'll find the limits before the bike warns you.
Pros
Cons
Twin Cam 96B engine, six-speed Cruise Drive transmission, electronic throttle control added later in run.
"Chrome-drenched cruiser that earns its reputation honestly."
The Fat Boy does exactly what it promises — low, wide, and torquey enough to pull stumps out of the ground from 2,000 rpm. The 103B upgrade in 2012 was meaningful; that extra torque genuinely transforms highway passing confidence, and the six-speed Cruise Drive keeps revs sane on long interstate hauls where the 96B used to buzz your hands numb at 110 km/h. That said, 317 kg is not a number you forget the first time you drop it in a parking lot, and the stock suspension is tuned for looks over function — hit a mid-corner bump and the front end sends you a firm reminder that this isn't a Canyon Carver. I've done 600-mile days on one and arrived tired but not wrecked; the seat is genuinely decent and the wind protection, surprisingly, is tolerable if you're not over six-foot.
Pros
Cons
Milwaukee-Eight 107 engine, redesigned chassis, updated brakes, modernized styling retaining classic disc wheel identity.
Used Buyer Review
"A genuine icon that rewards patient, budget-conscious buyers who shop carefully."
$9,000-$18,500 usedThe Fat Boy is Harley's most iconic cruiser for good reason — that solid-mounted Twin Cam or Milwaukee-Eight thumps with genuine character, and those fat disc wheels genuinely turn heads. Buy a 2018-or-newer Milwaukee-Eight version if you can stretch the budget. The 107ci engine is noticeably smoother and more tractable than older Twin Cams, and reliability improves meaningfully. Pre-2017 bikes aren't bad, just noisier and more prone to primary chain and compensator sprocket issues. Budget accordingly. Check the front forks obsessively on any used example — Fat Boys attract show-polishers who neglect real maintenance. Look for weeping seals, inspect the air cleaner for evidence of straight-piping abuse (melted nearby plastics), and run a CARFAX. These bikes often get dropped in parking lots by weekend warriors who then quietly flip them. Bent crash bar mounts and scuffed engine covers tell the real story. Overall it's a relaxed, confidence-inspiring machine that genuinely delivers on the cruiser promise without drama. Just buy one that's been ridden, not just admired.
