Built in the Image of Bold
Wide tires front and back. Classic Lakester cast aluminum wheels. The iconic steamroller stance, backed by a Milwaukee-Eight® 117 motor. LED lighting all around, Rider Safety Enhancements standard, and fine factory details that honor one of Harley-Davidson's most legendary silhouettes. The 2026 Fat Boy is bold by design.
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.
