Key Features

NOTHING LOOKS LIKE A FAT BOY: From its signature steamroller stance to new paint, a unique tank medallion, and full LED lighting, the 2026 Fat Boy defines one of Harley-Davidson’s most stand-out bikes.
BOLD COLORWAYS + MODEL-SPECIFIC TANK MEDALLION: The 2026 Fat Boy gets a fresh shot of attitude with a Fat Boy-specific tank medallion and bold new Olive Steel Metallic two-tone, joining Dark Billiard Gray, Vivid Black, White Onyx Pearl, and Brilliant Red. It’s a lineup built to make an entrance, no matter which shade you choose.
CLASSIC MACHINED LAKESTER WHEELS: Solid Lakester cast aluminum wheels, paired with wide front and rear tires, give the Fat Boy its unmistakable steamroller stance and planted look from every angle.
SIGNATURE HEADLAMP NACELLE + LED LIGHTING ALL AROUND: A sculpted chrome nacelle frames the front end of the Fat Boy, lit by a powerful 7" LED headlamp. Bright LED signals complete the bike’s all-around LED lighting package, blending timeless style with modern visibility. It’s a classic face, sharpened through a modern lens.
AS FAST AS IT LOOKS: The Milwaukee-Eight 117, Touring Intake, 2-into-2 exhaust, and performance-tuned suspension make the 2026 Fat Boy a show of force to match its legendary presence.
PUNCHY MILWAUKEE-EIGHT 117 CUSTOM MOTOR: The Milwaukee-Eight 117 feeds the Fat Boy exactly what it was built for: big torque and roll-on power that turns its solid, planted stance into something that moves with surprising quickness.
PERFORMANCE-TUNED FRONT AND REAR SUSPENSION: Fine-tuned damping rates improve rider comfort, keeping the Fat Boy smooth and composed even on long stretches of open highway.
TORQUEY 2-INTO-2 EXHAUST: Dual exhaust pipes bring a balanced look to the bike’s profile and deliver the deep, throaty note only a Harley-Davidson can.
AIRFLOW-OPTIMIZED TOURING INTAKE: Designed to move more air through the Milwaukee-Eight 117, the Touring Intake helps maintain steady power and smooth throttle response mile after mile.
CONFIDENCE MEANS MORE THAN YOU THINK: With ride modes, USB-C charging, and Rider Safety Enhancements, the 2026 Fat Boy is loaded with rider-focused tech you won’t notice until you need it.
HIGH-VIS 5" (127 MM) ANALOG GAUGE: The 5” (127 mm) analog gauge delivers essential ride data with a clean face, sharp detail, and a look that belongs on a bike as bold as the Fat Boy.
USB-C CHARGING THAT’S ALWAYS ON: USB-C charging comes standard, adding modern function to the unapologetic style of the Fat Boy and keeping you powered up without slowing down.
ADJUSTABLE BRAKE LEVER FOR EVERY RIDER: Fine-tune your reach for better control and braking confidence.
RIDE-READY HAND CONTROLS: With a thumb’s flick, you’ve got more command than ever. Switch between Road, Rain, and Sport modes on the fly, set cruise control when the highway stretches out, and trust built-in Rider Safety Enhancements — Cornering ABS, Traction Control, Drag-Torque Slip Control, and TPMS — to hold the line so you can focus on what’s in front of you.
