Riding into the sunset has never felt so bold. For 2025, Harley-Davidson reaffirms the Fat Boy’s legendary status—an icon reborn with modern muscle, fresh tech, and design upgrades that set it apart. Whether you’re a seasoned road warrior or eyeing your first heavyweight cruiser, the 2025 Fat Boy commands attention—and performance—like never before.
Bold Design, Timeless Heritage
From the moment you see it, the Fat Boy demands respect. Its hallmark wide, solid Lakester wheels—18 inches in both the front and rear—wrapped in 160/60 and 240/40 Michelin Scorcher 11 tires give it a powerful, planted stance. The iconic five-gallon teardrop tank and polished nacelle headlamp preserve the silhouette that turned heads when it debuted decades ago.
The 2025 model deepens its visual appeal with refined finishes and updated colorways including Billiard Gray, Blue Burst, and Vivid Black. A limited-edition version, the Gray Ghost, pays tribute to the 1990 original and features polished metal PVD finishes, yellow highlights, and a distinctive round air cleaner. Limited to just 1,990 units, the Gray Ghost is as much a collector’s piece as it is a road machine.
Powertrain That Packs a Punch
Beneath the Fat Boy’s bold exterior lies the Milwaukee-Eight 117 Custom V-Twin engine. Displacing 1,923 cc (117 cubic inches), it delivers an estimated 104 horsepower at 4,800 rpm and a commanding 126 lb-ft of torque at 3,000 rpm. This air- and oil-cooled beast blends smooth, predictable power delivery with that unmistakable Harley-Davidson growl.
The engine is paired with a 2-into-2 shotgun exhaust that offers both a retro visual and an assertive sound profile. A six-speed transmission keeps the ride composed whether you’re city cruising or devouring miles on the open highway. The powerplant is not just about numbers—it’s about feel. It’s the torque that pins you to the seat when the light turns green, the rumble that shakes your chest in idle, and the growl that accompanies every downshift.
Chassis, Suspension & Ergonomics
The Softail chassis continues to underpin the Fat Boy, offering a perfect blend of retro styling and modern ride dynamics. In 2025, Harley has fine-tuned key aspects to improve both comfort and control.
The front end sports 49 mm dual-bending-valve forks, designed to offer a smoother and more responsive ride. These are capped with classic beer-can fork covers, maintaining the bike’s heritage look. At the rear, a hidden coil-over monoshock with hydraulic preload adjustment allows riders to fine-tune their suspension for solo or two-up riding.
Stopping power comes from a 300 mm front disc brake with a four-piston caliper and a 292 mm rear disc with a two-piston caliper. Safety tech includes standard ABS, traction control, cornering-enhanced ABS, and Drag-Torque Slip Control, providing confidence in all conditions.
With a wheelbase of 65 inches, rake of approximately 30 degrees, and a low seat height of about 26.6 inches, the Fat Boy offers a planted, balanced stance that suits a wide range of riders. The ergonomics are relaxed yet assertive—exactly what you expect from a premium cruiser.
Infotainment & Rider Technology
Even though it leans into heritage design, the 2025 Fat Boy doesn’t ignore the need for modern conveniences. A combination analog speedometer and LCD display gives riders access to real-time ride data including gear position, fuel range, trip meters, and a clock. The system is compact, stylish, and easy to read even at highway speeds.
Three selectable ride modes—Road, Rain, and Sport—let you tailor throttle response and traction control to suit your conditions or riding style. These modes are managed via intuitive hand controls.
Additional features include a USB-C charging port for mobile devices, an adjustable front brake lever, and Tire Pressure Monitoring System (TPMS) integrated into the display.
Performance and Handling
On the road, the 2025 Fat Boy is all about presence and power. The low center of gravity, long wheelbase, and heavy curb weight (approximately 694 pounds) deliver a sense of grounded confidence. It’s not a flickable sportbike, but that’s not what it aims to be. The Fat Boy is built for long, steady rides and heads-up cruising.
Acceleration is brisk thanks to the generous torque curve. The big V-twin doesn’t need to be revved hard to deliver power. The gearing is set up to allow for relaxed cruising at freeway speeds, with plenty of reserve for passing without a downshift. With an estimated fuel economy of 47 mpg and a five-gallon tank, the Fat Boy is capable of about 235 miles per tank—perfect for long weekend rides.
Cornering on the Fat Boy requires effort due to its heft and wide tires, but it remains predictable and stable once you lean in. The suspension does a solid job of soaking up rough pavement, and highway ride quality is excellent.
