2025 Harley-Davidson® Fat Boy® vs 2025 Harley-Davidson® Low Rider® S
Few comparisons spark as much conversation among cruiser enthusiasts as the 2025 Harley-Davidson® Fat Boy® vs 2025 Harley-Davidson® Low Rider® S. Both ride on the latest Harley-Davidson® fundamentals, yet they deliver distinctly different personalities: one is an icon of muscular, chrome-polished presence and effortless torque, the other a blacked-out, performance-bent machine honed for aggressive riding.

Key Features
This matchup—2025 Harley-Davidson® Fat Boy® vs 2025 Harley-Davidson® Low Rider® S—pivots on two distinct interpretations of style and intention. The Fat Boy features 18-inch machined Lakester wheels shod in massive tires beneath cutback fenders, a bright polished chrome headlight nacelle, and a classic rounded tank reimagined with a bold medallion and premium paint. Its updated monoshock keeps comfort in focus while staying composed when you pick up the pace, and its two-into-two exhaust underscores the bike’s broad-shouldered presence with a rich V-twin soundtrack. The Low Rider S leans hard into performance: high-flowing Heavy Breather intake, a lightweight two-into-one exhaust, a tall monoshock for added cornering clearance, and a blacked-out, West Coast style with sharp red accents that punch through the matte and gloss finishes. Both bikes bring useful tech to the party. The Fat Boy’s five-inch analog gauge integrates a digital display that surfaces Ride Modes, while the Low Rider S runs a riser-mounted four-inch analog unit with a digital window for Safety Enhancements and Modes. Updated ergonomic hand controls, USB-C charging, and a newly integrated electronics suite tie it all together, and both offer Cruise Control and Traction Control to reduce fatigue and boost confidence during long rides near Frederick, MD. For riders comparing 2025 Harley-Davidson® Fat Boy® vs 2025 Harley-Davidson® Low Rider® S on feature breadth, both check the boxes—your style and riding intent decide the rest. Eisenhauer's Chesapeake Harley-Davidson® can walk you through each detail.
Dimensions
Both machines share the modern Harley-Davidson® cruiser foundation, yet they differ in stance and feel. The Fat Boy sits low and wide, emphasizing stability with its broad 18-inch wheels and muscular tire profile that plant the chassis at a stop and on the highway. The cutback fenders frame those wheels for a commanding visual footprint. By contrast, the Low Rider S rides taller out back thanks to its elevated monoshock, which effectively adds cornering clearance and subtly changes rider posture for assertive handling. The steep-backed solo seat on the Low Rider S keeps you braced during hard launches and rapid acceleration, while the Fat Boy’s saddle and ergonomics emphasize relaxed control on long stretches. Both bikes maintain compact proportions that inspire confidence maneuvering through town near Frederick, MD, yet still feel substantial on open roads. Riders who prefer a grounded, boulevard-strong profile often gravitate to the Fat Boy; those who want a slightly more aggressive, raised rear stance tend to favor the Low Rider S.
Engine
The heart of each model is a Milwaukee-Eight® 117 powerplant, but tuning and aspiration distinguish their personalities. The Fat Boy employs the Milwaukee-Eight® 117 Custom engine—high-performance by design—delivering the signature Harley-Davidson® sound and torque-rich thrust that make long-mile cruising feel effortless. A high-flowing, two-into-two exhaust complements that character with classic symmetry and a deep, authoritative note. The Low Rider S ups the ante with the Milwaukee-Eight® 117 H.O. (High Output) tune, optimized to deliver peak power higher in the rev range. Its Heavy Breather intake faces into the wind for improved airflow and an aggressive look, while the lightweight, blacked-out two-into-one exhaust dials in responsiveness. Both engines balance modern refinement with visceral feedback, and both interface with Ride Modes and Traction Control to adapt the power delivery. Whether you lean toward broad, easy torque or a sharper, high-rev edge, both options are compelling.
Performance
On the road, their characters separate further. The Fat Boy’s updated rear monoshock favors comfort without flinching under assertive throttle, making it a natural at soaking up miles and settling into an unhurried rhythm. The chassis and tire footprint telegraph stability, making lane changes and highway passes predictable and smooth. The Low Rider S takes a sportier approach: the tall monoshock and performance-focused componentry sharpen turn-in, increase lean potential, and keep the bike composed under hard braking and acceleration. Braking hardware is tuned for riders who like to push limits, while the H.O. engine tune and two-into-one exhaust deliver crisp throttle response exiting corners. Both machines benefit from Ride Modes and electronic aids when conditions change near Frederick, MD—wet pavement, cold mornings, or a spirited backroad detour. If you prioritize long-haul comfort and visual muscle, the Fat Boy shines; if your instinct is to carve and charge, the Low Rider S is your arrow.
Drive Train
Both bikes deploy a robust, proven driveline tailored to the Milwaukee-Eight® 117’s output. A precise 6-speed gearbox puts the right ratio within easy reach, with deliberate, positive shifts that suit steady cruising or aggressive acceleration. The final drive remains a durable belt—quiet, low-maintenance, and torque-friendly—supporting smooth power transfer to the rear wheel. Wet, multi-plate clutches manage heat and engagement cleanly, with lever effort tuned for comfort in city traffic and high-speed transitions alike. In practice, the Fat Boy’s driveline complements its calm, confident demeanor with relaxed, low-rpm cruising and quick roll-on authority. The Low Rider S takes advantage of its H.O. tune and freer-breathing intake and exhaust to spin up faster, encouraging shorter shift intervals when you want to keep the motor on the boil. Both approaches thrive within the Harley-Davidson® Softail DNA—durable, responsive, and ready for customization.

Chassis
These cruisers share a modern Harley-Davidson® chassis that preserves the hard-tail look while delivering contemporary compliance and control. The Fat Boy highlights visual heft—18-inch Lakester wheels, cutback fenders, and bright polished chrome on the headlight nacelle—paired with a suspension package updated for comfort and composure. The Low Rider S puts its chips on performance posture: stripped-down bodywork, a tall rear monoshock for extra cornering clearance, and top-shelf suspension and braking components that reward assertive riding. Both bikes keep unsprung mass and geometry in check to balance stability with agility, and both benefit from strong, predictable braking that inspires confidence in daily traffic as well as on weekend blasts. Where the Fat Boy commands attention with its silhouette and low-slung stance, the Low Rider S communicates intent from the first turn of the bars—two valid expressions of the same engineering discipline, refined to different outcomes. Eisenhauer's Chesapeake Harley-Davidson® can help you feel the difference in setup and ergonomics before you choose your path.
Electric
Harley-Davidson® wrapped both bikes in classic analog instrumentation paired to modern digital intelligence. The Fat Boy runs a clear five-inch analog gauge with a built-in digital display that presents Ride Modes and key trip data at a glance. The Low Rider S uses a riser-mounted four-inch analog unit with a digital window that surfaces Ride Modes and Rider Safety Enhancements in a compact, performance-oriented position. Updated hand controls across both models support Cruise Control, Traction Control, and mode selection, while an adjustable brake lever lets you fine-tune reach. USB-C charging is standard on both platforms, keeping phones and nav devices powered during all-day rides. The Low Rider S also spotlights LED lighting—5.75-inch LED headlight, LED turn indicators, and taillight—for bright, efficient visibility. Classic form meets modern function on both dashboards, ensuring you get information quickly without clutter, whether you are cruising downtown or crossing county lines near Frederick, MD.
Rider Safety Enhancements
Each model integrates an expanded suite of electronic aids designed to support the rider without diluting feel. Both bring Anti-lock Braking System (ABS), Traction Control, and Cruise Control into a cohesive package that works hand in glove with Ride Modes. The Low Rider S highlights a full set of Rider Safety Enhancements and makes those features easy to access via updated hand controls and the analog-digital display. The Fat Boy’s controls likewise accommodate Cruise Control and Traction Control, and its integrated display clearly surfaces mode selections and status. These systems contribute during low-traction scenarios, reduce fatigue on long hauls, and help stabilize the bike during abrupt inputs. Importantly, both retain Harley-Davidson® character—transparent when you want them to be, supportive when conditions turn unpredictable. Our team at Eisenhauer's Chesapeake Harley-Davidson® can explain exactly how the systems interact with engine mapping and braking so you can tailor the ride to your preferences.
