The original fat custom icon matches unmistakable style with a High Output Twin Cam 103B™ engine.
Sometimes something comes along that changes everything. When Willie G. Davidson rode the Fat Boy® model into Bike Week the first time, let’s just say it stopped traffic. No one had ever seen a factory custom motorcycle with this much visual impact before. The look was pure Harley, yet totally new. In the years since, the Fat Boy hasn’t let up. From the chrome of the solid disc wheels, to the muscular lines of the new High Output Twin Cam™ 103B™ engine to the curve of its distinctive rear fender, this machine is built to make an impact. Ride one and you’ll understand.
