HARLEY-DAVIDSON Fat Boy Lo (2011-2012) Specs, Performance & Photos

The Fat Boy family of cruiser machines was born in 1990 with the Harley-Davidson Fat Boy, also known as the FLSTF, from 1990 to 2017. From 2018, the bikes were coded as FLFB and FLFBS.

Over its production period, the Fat Boy underwent several design and performance modifications, including five displacement increases, from 1,330cc in 1990 to 1,868cc in 2018.

In 2011, alongside the standard Fat Boy model, the American motorcycle manufacturer launched the Harley-Davidson Fat Boy Lo, a darker, and like its name says, a low machine with lowered suspension and black-finished elements.

The 2011 model came with several new elements, including a Security Package with factory installed H-D Smart Security System with a hands-free fob, an ABS, hand controls with fewer wires, a new odometer switch, and a hazard warning switch with a single button.

As for appearance, the 2011 Harley-Davidson Fat Boy Lo packed a powder-coated engine with polished cooling fins and head covers, black exhaust pipes with polished mufflers, a black frame, black fenders, and black full disc bullet hole aluminum wheels with polished rims.

As for performance, the 2011 Fat Boy Lo took its muscles from a 1,584cc air-cooled V-twin engine fed by an electronically controlled fuel injection system, delivering smooth power, fast acceleration, and 127 Nm (94 lb-ft) torque with a maximum peak at 3,000 rpm.
