HARLEY-DAVIDSON Fat Boy (2015-2016) Specs, Performance & Photos

Harley-Davidson's Fat Boy story began in 1990, when the American manufacturer launched a new line of cruiser motorcycles, also known as FLSTF, from 1990 to 2017 and FLFB and FLFBS from 2018.

The bike was known for its fat, muscular appearance, distinctive styling, and powerful engine. From the start, the bike was fitted with classic elements, including a teardrop-shaped fuel tank, valanced fenders, and full-disc aluminum wheels with fat tires.

In 2015, the American motorcycle manufacturer released the Harley-Davidson Fat Boy, a cruiser machine that underwent various design, technical, and performance modifications, including three displacement increases.

Starting from a 1,130cc displacement in 1990, the bike was revised for the 2000 year model, increasing its displacement to 1,450cc. In 2007, the bike's engine had another rise in displacement to 1,584cc. In 2012, the Fat Boy featured the third displacement increase, from 1,584cc to 1,690cc.

The 2015 Harley-Davidson Fat Boy took its muscles from a 1,690cc four-stroke V-twin air-cooled engine with an electronically controlled fuel injection system that delivered smooth power, fast acceleration, fewer emissions, better fuel efficiency, and 134 Nm (99 lb-ft) torque at 3,500 rpm.

The 2015 machine rolled on full disc aluminum wheels with a bullet hole design, covered by a chopper-style fender on the rear and a custom fender on the front. A stylish black powder-coated engine was between the wheels with chromed head covers and cooling fins.

When it was released in 2015, the bike had an MSRP of $18,849, while eight years later was for sale with an average price of $11,000.
