HARLEY-DAVIDSON Fat Boy Lo (2013-2014) Specs, Performance & Photos

The Harley-Davidson Fat Boy was a Softail cruiser motorcycle produced by H-D since 1990, also known as the FLSTF through 2017, and since 2018, it has been coded as FLFB and FLFBS.

A false etymology circulated around that the bike's name was chosen after the Fat Man and Little Boy atomic bombs thrown on Japan during World War Two. However, H-D's styling and product development vice president debunked the rumor, confirming that the name was simply descriptive.

In 2013, the American motorcycle manufacturer launched the Harley-Davidson Fat Boy lo, a version derived from the standard model, with a blacked-out appearance, a lowered suspension, and the lowest seat height among Fat Boy versions.

The bike's dark appearance was complemented by black elements, including the front fork covers, a round headlight with a black case, front and rear fenders, fuel tank, exhaust pipes with satin chrome mufflers, engine with satin chromed head covers and cooling fins, and a pair of black bullet-hole full disc aluminum wheels with polished rims.

In the performance department, the 2013 Harley-Davidson Fat Boy Lo took its muscles from a 1,690cc four-stroke air-cooled V-twin engine with an electronic fuel injection system in charge, delivering excellent throttle response, fast acceleration, fewer emissions, and 132 Nm (97 lb-ft) torque with a peak at 3,250 rpm.

In 2013, the bike was released with an MSRP of $16,799; in 2023, it was for sale with an average price of $7,000.
