Yes, it's fat and that is why it gets its name. The Fat Boy has a unique design and there is a generous dose of chrome and that is not all. It comes with a load full of features too. It features a wide FLH-style handlebar, a textured leather seat insert, custom metal fenders and a shotgun-style dual exhaust system. The Fat Boy is powered by a Twin Cam 103 1690cc engine that produces a generous amount of power and it's a highway cruiser so don't try and tame it by riding it in the city. It's clearly out of place there.
