The Harley-Davidson Dyna FXDF Fat Bob comes with a pretty unique name, but what’s more unique than its tag is the bike itself. This custom cruiser is made from the stuff that riders of all shapes and sizes absolutely crave.
With forward-mounted foot controls, a drag-style handlebar, and a sleek, two-up seat, the Fat Bob motorcycle creates an aggressive riding position that commands respect wherever it goes. Though it looks the part of a ’fat’ cruiser, the Dyna Fat Bob’s characteristics emphasize character aggression, highlighted by a 130 mm wide front tire with a gnarly, robust tread pattern. Fat Boy also sports a sporty front fender with painted brace supports, a Bobtail rear fender with chrome supports, a one-up, two-piece Dyna classic seat, a stainless steel drag-style handlebar, polished aluminum triple clamps, and a chrome, "Tommy Gun" 2-1-2 collector exhaust system with dual mufflers.
At the belly of the Dyna Fat Boy lies a powerful and new rubber-mounted 1690cc Twin Cam103 V-Twin engine with Electronic Sequential Port Fuel Injection (ESPFI). The engine is capable of delivering 92 lb/ft of torque, providing enough meat and grinds power to make other bikes of its class envious. Making it more impressive for the Dyna Fat Boy is that its engine has been mated to a six-speed Cruise Drive transmission, making that ride that much more impressive.
When Harley-Davidson designed the 2012 Dyna FXDF Fat Bob, they had one clear-cut mission in mind: to make the bike as fat and meaty as possible. Thanks to an aggressive neo-retro style and a spectacularly powerful engine, the American bike maker managed to exceed even their own lofty expectations.

Ultimate Motorcycling----"When Harley-Davidson designed the 2012 FXDF Fat Bob, that had one thing in mind - just what the name implies, Fat. With an aggressive style, double chrome headlight and 130-mm front tire, the 2012 Fat Bob arrives stock with that mean, custom look. Stock items from the Motor Company include forward controls, drag-style handlebars, and an exposed under-seat battery box. Out back, the Fat Bob features chrome-covered, coil-over shocks showcase the beefy 180 mm wide rear tire."
