Wrap your eyes around the Fat Boy®, if you think you can. There’s a whole lot to love here. It all starts up front with FL-style fork tubes and huge solo chrome headlight. Generous floorboards are welcoming of any boot size. A robust eighty-eight cubic inches of dual-counterbalanced Twin Cam goodness is available carbureted or in super-smooth EFI.

The engine belts out its baritone song through a set of shotgun pipes. And the broad tires on Silver Aluminum Disc wheels take all this beef to the road in a style like no other. If you’re ready for something bigger than life, get in the saddle of a Fat Boy®. Once you do, the grin on your face will no doubt get bigger, too.

FLSTF/I Fat Boy® Model Overview
One of the most recognizable motorcycles on the road, FLSTF/I Fat Boy offers a muscular profile with fat tires wrapping disc wheels front and rear. A big chrome headlight mounted on wide handlebars, a custom flared front fender and shotgun exhaust announce its arrival. Parked or rolling, the wide handlebar on the Fat Boy completes the large, aggressive and unmistakably Harley-Davidson look. New for the first time in the history of the Fat Boy, Chrome Aluminum Profile Laced wheels are an available option.
