Building on the Fat Boy® legacy, the Fat Boy® Lo brought a darker, slammed appearance to the world of boulevard cruisers. From front to back, this custom cruiser shows attitude, with custom, black bullet hole wheels, a denim black frame, blacked-out covers and header shields, and satin chrome in all the places mirror chrome would normally reside. A slammed, narrow-cut seat rides just 24.25-inches off the ground, while the forward foot controls and low, 1.25-inch handlebar create a secure stance that inspires a cruising state of mind. With the new addition of anti-lock brakes in the Security Package option, the Fat Boy Lo truly remains at the head of the pack.
