2013 Harley-Davidson Softail® Fat Boy®

Softail® Fat Boy®

The original fat custom icon with a burly style that's often imitated but never duplicated. The 2013 Harley-Davidson® Softail® Fat Boy® FLSTF model is one of the quintessential cruiser motorcycles. Hearkening to the 'hardtail' choppers of the 1960s and 1970s, the Harley-Davidson Fat Boy motorcycle keeps that heritage alive more than 40 years later. The FLSTF Fat Boy is the original 'fat custom' bike - laid-back and luxurious with an unmistakable profile on the road. The Harley® Fat Boy features an air-cooled Twin Cam 103™ Harley engine with 6-speed Cruise Drive® transmission, providing more power for passing, hill-climbing, and riding with a passenger and luggage. Take a seat on this Harley and get the experience of one of the 2013 H-D® cruiser motorcycles. Learn about other Harley Softail motorcycles in addition to this cruiser. Look at the Heritage Softail® Classic model, too; this classic motorcycle is ready for the road. If you like choppers, be sure to take a look at the Fat Boy Lo model, another of the custom Harley motorcycles.
