Key Features
When you compare the 2025 Harley-Davidson® Fat Boy® vs 2025 Harley-Davidson® Breakout®, the design contrasts are instantly clear. The Fat Boy stands broad-shouldered and sculpted, its solid-disc Lakester wheels, massive rubber, and new tank medallion amplifying a signature silhouette that has defined generations. The Breakout, by contrast, is long, purposeful, and chopper-inspired, riding on a bold 21-inch front wheel and that wide 240mm rear, with premium Factory Custom paint options such as Midnight Firestorm making a statement before the engine ever fires. Both introduce a Milwaukee-Eight® 117 Custom engine engineered for torque-rich acceleration and relaxed highway cadence, routed through high-flow two-into-two exhausts that deliver a signature V-twin soundtrack. Ergonomically updated hand controls make essential functions intuitive, and both bikes incorporate Ride Modes and Traction Control for adaptable response across conditions. The Fat Boy’s five-inch analog gauge and the Breakout’s four-inch analog display each incorporate a digital screen for Ride Modes and trip data, while USB-C keeps devices powered for navigation or communication via a Bluetooth® headset. At Lawless Harley-Davidson®, we see these as two interpretations of modern cruiser excellence: one muscular and monumental, the other stretched and athletic, with shared technology enabling confident, customizable riding near St. Louis, MO.
Dimensions
The Fat Boy projects compact might, anchored by 18-inch machined Lakester wheels wrapped in substantial tires, creating a planted stance under cutback fenders and the iconic headlamp nacelle. The Breakout contrasts with a 21-inch front wheel and 34-degree rake for old-school chopper style updated by modern geometry, while its 240mm rear tire maximizes the contact patch for acceleration. Both bikes place the rider in a commanding posture, with updated control ergonomics to reduce reach and improve leverage at low speed or during quick transitions. The wide-tire look is shared, but the Fat Boy reads as sculpted and muscular, while the Breakout looks stretched and ready to sprint. These dimensional differences become especially noticeable while carving city streets or cruising open roads near St. Louis, MO, where the Fat Boy’s stout footprint feels reassuring and the Breakout’s long-and-lean profile offers a distinct sense of drama.
Engine
Harley-Davidson® endowed both models with the Milwaukee-Eight® 117 Custom V-twin, bringing deep torque and a confident, immediate response. The engine’s character is unmistakable: a broad, low-end pull that hustles you off the line, smooth midrange for decisive passing, and relaxed cadence at highway speeds. Each model pairs this powerplant with a high-flow two-into-two exhaust tuned to deliver a rich, throaty note that suits the bike’s visual identity. The Breakout adds a new touring intake for high-flow performance and a performance-forward look. In both cases, the 117 Custom balances visceral feel with refined manners, giving riders the sound and sensation they expect from a flagship Harley-Davidson® cruiser while meeting today’s expectations for responsiveness and smoothness.
Performance
On the road, both cruisers deliver torque-laden acceleration and composed tracking. The Fat Boy benefits from updated monoshock suspension that enhances comfort while staying composed during aggressive riding, so it feels more settled over broken pavement and under hard throttle. The Breakout emphasizes nimble handling for its chopper-inspired stance, using refined geometry and high-quality suspension to make quick direction changes feel natural. A single 300mm front disc on the Breakout provides confident stopping power and highlights the bike’s bold 21-inch front wheel. Ride Modes and Traction Control help both bikes adapt to your conditions and riding style. The result is a pair of cruisers that deliver massive thrust with a surprising degree of polish, allowing you to enjoy long-mile highway cruising or spirited in-town riding with equal confidence.
Drive Train
Power delivery on both bikes is fluid and predictable, with a smooth-shifting six-speed gearbox that puts the Milwaukee-Eight® 117 Custom’s torque to efficient use. Throttle response is well-calibrated to each Ride Mode, giving you the ability to tune the character of the engine’s output. The two-into-two exhaust systems are more than a styling cue — they are engineered for high-flow performance, helping the engines breathe and respond crisply. Combined with a low-maintenance final drive and intuitive clutch feel, both the Fat Boy and the Breakout translate abundant torque into forward motion with an ease that riders notice immediately. The overall sensation is one of authority without excess effort, underscoring how contemporary engineering elevates the classic cruiser experience.

Chassis
Both models are built around the modern Harley-Davidson® Softail chassis, which delivers a rigid foundation for stability and responsive handling. The Fat Boy’s stance is broad and stout, the kind of visual mass that telegraphs confidence at a standstill and composure in motion. Its 18-inch Lakester wheels and cutback fenders create a muscular, unmistakably Fat Boy profile. The Breakout’s elongated lines, 34-degree rake, and 21-inch front wheel keep chopper heritage alive while revised geometry preserves nimbleness and predictability. Updated hand controls and an adjustable brake lever on both bikes improve ergonomics and fine control, while suspension tuning keeps each model poised when cornering, braking, or accelerating hard. Whether you gravitate toward the Fat Boy’s muscular minimalism or the Breakout’s stretched athleticism, the chassis tuning makes each feel sorted and ready for everyday riding.
Electric
Classic form meets modern function with electrical and interface updates that enhance clarity and convenience. The Fat Boy features a large, five-inch analog gauge with an integrated digital display for Ride Modes and essential trip data; the Breakout uses a four-inch analog display with a complementary digital screen. Both bikes feature USB-C charging to keep devices powered for navigation, music, or comms via a Bluetooth® headset, and their LED lighting is compact, bright, and consistent with each bike’s visual language. Updated hand controls integrate modern features without distracting from the bikes’ clean lines, preserving the analog aesthetic while delivering digital versatility. Thoughtful integration means the tech supports your ride rather than defines it, helping you stay informed and connected without overwhelming the senses.
Rider Safety Enhancements
Each model benefits from Rider Safety Enhancements designed to help with traction, braking, and stability. Ride Modes allow you to tailor throttle response and intervention thresholds to your preferences and conditions; Traction Control helps manage available grip when the surface turns slick or unpredictable; and ABS braking adds confidence when you need to stop with authority. The Breakout’s dynamic ABS and the Fat Boy’s integrated safety systems are tuned to the character of each motorcycle, and both include an adjustable brake lever so you can fine-tune reach and feel. For riders coming from Memphis, TN, or traveling through Evansville, IN, these enhancements translate into real-world reassurance when weather, road surfaces, or traffic patterns change unexpectedly. Our goal is to help you ride with more confidence, not complicate what should feel intuitive.
