The name may be Fat Boy®, but the look is all muscle. This is the icon, riding on a 240mm rear tire, 160mm front tire and solid disc wheels. You get satin chrome finishes and signature LED lighting. This version is lighter than the previous generation Fat Boy models, and its slinging torque from a Milwaukee-Eight 114 engine. You’ll notice the difference the instant you crack the throttle. Sometimes a bike comes along that changes the landscape. The Fat Boy is one of them.
