2017 Harley-Davidson Fat Bob Blacked-out finishes. Dual bullet headlamps. This one raises a ruckus just rolling into town. It takes styling cues from the barrel of a Tommy Gun. Subtle is not the word that comes to mind when describing the Fat Bob . Tommy Gun exhaust. A unique dual headlight and custom LED tail light. Fat rubber rolling on machined disc wheels. And performance that lets you get down to business with the High Output Twin Cam 103 engine and dual disc brakes. The look is powerful; and so is the ride.
