The original 1990 Fat Boy, designed by Willie G. Davidson and Louie Netz, boasted a contemporary look with a monochromatic silver finish, wide handlebar with massive chrome headlight housing, and rolled on beefy aluminum disc wheels with a fat front tire—defining marks of the Fat Boy throughout its run. Davidson designed the winged tank logo, which also stuck around over the years. The Fat Boy got regular updates until 2018, until it took new form on the reinvented Softail chassis featuring the Milwaukee-Eight engine. The current standard model keeps those defining badass cues, from the disc wheels to the huge headlamp and nacelle, but the newest, 30th Anniversary Fat Boy goes for a more stealthy vibe, wearing mostly dark paint with bronze highlights, as well as a (and, yes, blacked-out) Milwaukee-Eight 114 engine. The 30th Anniversary Fat Boy will be limited to just 2,500 units, with each one getting a serial number plate on the fuel tank console.
