Harley Davidson FLSTFB Softail Fat Boy Lo (2010 – 2011)

Harley Davidson FLSTFB Softail Fat Boy Lo (2010 - 2011)

The Harley-Davidson FLSTFB Softail Fat Boy Lo is a stripped-down, no-frills cruiser that embodies the spirit of rebellion and freedom. Its low-slung stance, courtesy of 1.15-inch lowered suspension, puts the rider firmly in command, with a seat height of just 24.25 inches making it one of the most accessible Harleys on the market.

At its heart lies the Twin Cam 96B engine, its black powdercoated powertrain a testament to the bike’s dark side. The ESPFI fuel injection system provides seamless power delivery, while the Helical cut 5th gear adds a rich, musical note to the exhaust note.

The Fat Boy Lo is an uncompromising, stripped-down ride that defies convention and invites riders to take control. With its blacked-out aesthetic, dark finishes, and aggressive stance, this Harley-Davidson is not for the faint of heart – it’s for those who crave raw power and unbridled freedom, and will stop at nothing to get it.
