– 2006 Harley-Davidson FLSTF/I Fat Boy

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.
