FAT BOY GRAY GHOST

BORN A LEGEND. BACK TO RAISE HELL.

The 2025 Harley-Davidson® models represent the future of motorcycling. With upgraded engine performance, cutting-edge safety features, and state-of-the-art technology, this year's lineup pushes the boundaries of what's possible on two and three wheels.

Some bikes make history. Others rewrite it. In 1988 and 1989, Willie G. Davidson rode early Fat Boy® prototypes into Daytona, seeking direct feedback from riders and igniting a legacy that would span generations. By 1990, the Fat Boy was born, quickly becoming one of the most legendary models in Harley-Davidson history. Now, 35 years later, the new 2025 Fat Boy® Gray Ghost charges forward, bringing that legacy full circle. Inspired by the riders who made it an icon, this tribute honors the past while the next generation keeps the fire burning.

HIGHLIGHTS:
• Relaxed riding position.
• Forward foot controls.
• Passenger seat.

DESIGN
The original Fat Boy® set the standard, and the all-new 2025 Fat Boy® Gray Ghost takes it further. Its legendary silver and yellow color scheme returns, now with a stunning mirror-like finish created through an advanced Physical Vapor Deposition (PVD) process, plus full LED lighting for a bold, modern edge.

HIGH-PERFORMANCE
The Fat Boy® Gray Ghost blends classic style with modern power. The Milwaukee-Eight® 117 Custom V-Twin Engine and timeless round air cleaner give it the perfect mix of muscle and attitude.

INNOVATION
All the benefits of Rider Safety Enhancements and Ride Modes are hidden in classic cruiser form and managed with intuitive, ergonomic hand controls.
