The Harley-Davidson Softail Fat Boy has been reborn, its muscular presence more pronounced than ever with all-new solid-disc wheels and a beefy 240mm rear tire. At 29 pounds lighter, this iconic custom motorcycle now packs an even more potent punch from the Milwaukee-Eight V-Twin engine.

But make no mistake – this is not just any bike; it’s a statement piece that stops traffic. With its satin chrome finishes and intimidating stance, the Harley-Davidson Softail Fat Boy 2018 is ready to unleash its full fury on the roads. It’s time to experience the ultimate in custom motorcycle design – the most powerful, agile, and responsive cruiser in Harley-Davidson history.
