From the dealer's page

In the saddle of a Harley-Davidson® Softail®, no road is ever lonely. Sunlight breaks through treetops to dance on chromed steel. The wind offers its constant stream of praise. And the world unfolds before you with open arms. Maybe it’s because nothing else on the road compares with the timeless hardtail styling ... and nothing else feels like a Twin Cam 88B™ power mill rigid-mounted to the frame. Counterbalancing takes care of all but the good vibrations. You and the motorcycle become one, united by an unbreakable bond. Then you feel the hidden rear suspension smooth out the ride with a full 4" of travel. There’s no denying you’re in the saddle of a rolling masterpiece. This year, the Softail family of custom motorcycles welcomes its latest member. We invite you to turn the page and take a gander at the clean lines of the new Heritage Softail®. Additionally, all new bobtail models get a shot of adrenaline in the hindquarters — a brawny, road-hugging 200mm tire under a new wider fender. More rubber to stick to the pavement. More style to keep the eyes glued. 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. For a limited time, we are offering one-of-a kind, custom color combinations that are over and above the standard two-tone color options available during the model year. These limited color combinations come with a custom decal that is only available through the Custom Color program. Each color has unique complementing pinstripes.
