Introducing the 2025 Fat Boy® Gray Ghost, a tribute to the 1990 original. Reimagined with more power and attitude, it’s back to make history again.
The Icons medallion on the rear fender speaks to this unique collection and the incredible exclusivity of this motorcycle.
Limited to just 1,990, each bike is individually numbered to honor the original 1990 Fat Boy®—never to be made again.
The original and most iconic Fat Boy® tank medallion is back with flat, straight wings in a brushed silver finish.
A more powerful Milwaukee-Eight® 117 V-twin paired with a classic-style round air cleaner, delivering strong torque for fast launches and effortless highway cruising.
Updated monoshock suspension offers a smoother ride when you want comfort and stays firm when it’s time to get aggressive.
Updated design pays homage to the original Fat Boy’s two-into-two chrome pipes while delivering improved high-flow performance.
The five-inch tank-mounted analog gauge nods to the original Fat Boy®, now paired with a digital display that shows key ride data, including gear position and selectable Ride Modes (Road, Rain, and Sport), so you can fine-tune your ride like never before.
Ergonomic, intuitive hand controls give you quick access to Cruise Control and new selectable Ride Modes.
Once reserved for details like tank medallions and exhaust shields, PVD now takes over the Fat Boy® Gray Ghost. Its fuel tank and fenders feature this high-tech, chrome-like finish for the first time on a production Harley-Davidson®, creating a head-turning mirror effect under H-D’s signature clear coat.
