HARLEY-DAVIDSON 2026 FAT BOY™

If blending in is your style, the 2026 Fat Boy isn’t the bike for you. Its iconic chrome headlight nacelle, bold lines, and one-of-a-kind stance turn every arrival into something worth noticing.

At a Glance

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.

Tech Specs

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.

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.

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.

Ride-Ready Hand Control

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.

Signature Headlamp Nacelle + LED Lighting All Around

A sculpted chrome nacelle frames the front end of the Fat Boy, lit by a powerful 178 mm 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.

“Every time I park it, I catch myself looking back at it. I’ve never done that with any other bike I’ve owned, but there’s something about the Fat Boy that makes you 

want to take it in for a second before you walk away.

Make Your Entrance Everywhere

From its performance-tuned 117 motor and 2-into-2 exhaust to full LED lighting and retro-inspired tank medallion, the 2026 Fat Boy was made to make every lane its own. Ride modes and modern tech give you confidence without compromising what makes this bike unmistakably Fat Boy.

RIDER SAFETY ENHANCEMENTS

Harley-Davidson’s Rider Safety Enhancements is all about giving you that extra peace of mind when things get a little unpredictable. It’s a set of smart tech that steps in during tricky situations, helping the bike handle traction while you’re accelerating, braking, or slowing down. With the Cornering Rider Safety Enhancements, the bike even adjusts for cornering, keeping things smooth and steady without you having to think twice.

Anti-lock Brake System (ABS)

ABS is designed to prevent the wheels from locking under braking and helps the rider maintain control when braking in a straight-line, urgent situation.

Traction Control System (TCS)

The TCS is designed to keep the rear wheel from “spinning out” when the motorcycle is accelerating in a straight line and enhances rider confidence.

Drag-Torque Slip Control System (DSCS)

DSCS is designed to reduce excessive rear-wheel slip and help prevent rear-wheel lock under powertrain-induced deceleration, which typically occurs when the rider makes an abrupt downshift gear change or quickly reduces the throttle while on wet or slippery road surfaces.

Tire Pressure Monitoring System (TPMS)

TPMS alerts the rider through the information display to low or high tire air pressure. Maintaining proper tire air pressure is important both for vehicle performance and tire life.

Cornering Enhanced Anti-lock Brake System (C-ABS)

C-ABS is a variant of ABS that takes into consideration the lean angle of a two-wheel motorcycle, or the lateral acceleration of a Trike model. The brake pressure required to limit wheel slip when cornering is typically or lower than the pressure required under straight line operation.

Cornering Enhanced Traction Control System (C-TCS)

C-TCS is designed to prevent the rear wheel from excessive spinning under acceleration when going straight or cornering.

Cornering Drag-Torque Slip Control System (C-DSCS)

On bikes equipped with C-DSCS, the system helps keep the rear wheel from slipping or locking up when you quickly downshift or let off the throttle, especially on wet or slippery roads. When turning, it can adjust based on how much a two-wheel bike is leaning or the side-to-side motion on a Trike.
