Harley Davidson Softail Fat Boy -114 - 115th Anniversary (2018)

The wait is over for the most anticipated motorcycle of 2018 – the Harley-Davidson Softail Fat Boy. This iconic ride has undergone a significant transformation, shedding 29 pounds while gaining muscle in every aspect.

Its powerful engine, now available with Milwaukee-Eight 107 or 114 Big Twin options, pumps out an unstoppable force that will leave onlookers speechless. Paired with the beefy 240mm rear tire and all-new solid-disc wheels, this Fat Boy is ready to take on any road.

The ride experience is nothing short of exhilarating, with a lighter and stiffer chassis, high-performance suspension, and a fully counter-balanced Milwaukee-Eight V-Twin engine that delivers smooth, unrelenting torque.
