2013 FLSTF103 FAT BOY Vivid Black with Pinstripe. Twin Cam 103B™ powertrain finished in Black powder-coat with chrome covers and Six-Speed Cruise Drive® Transmission. The legendary Fat Boy® motorcycle defined the “fat custom” category and imitators everywhere tried to copy its magic. But this original continues to turn heads wherever it rolls, with fat tires, fat bars, a fat fender and a big, powerful, black powder-coated, counter-balanced Twin Cam 103B™ engine. The Fat Boy® model is the very definition of a heavyweight motorcycle, delivering a bold styling statement and a wide, comfortable riding stance.
