2017 Harley-Davidson Fat BoyThe 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 Daytona Bike Week the first time, it stopped traffic. In the years since, the Fat Boy hasn’t let up. From the chrome solid disc wheels, to the muscular lines of the 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.
