From the dealer's page

EVERY NOW AND THEN, SOMETHING WILL COME ALONG AND PUT EVERYTHING RIGHT WHERE IT BELONGS. Saddle up on the new Fat Bob™ and watch the world quickly take its place over the flat internally-wired handlebar on black risers. Stand alongside and your eyes go right to the tommy-gun exhaust shield on the custom pipes. Like every bike in the family, the design centers on the power and glory of a vibration-isolated Twin Cam 96™ engine. It’s finished in black, with polished covers. The air cleaner cover is new, unique to the Dyna® family. Choose from mid-mount or forward controls. Even the rubber takes its own path. Solid 16-inch wheels front and rear, wearing an aggressive tread pattern all their own. We couldn’t help but finish up with an outrageous dual chrome headlamp.
