Fat Bob® 114

Fat Bob® 114

In Brief

From the modern, aggressive look of its 2-1-2 upswept exhaust and asphalt-devouring fat tires to the massive torque of the Milwaukee-Eight® 114 engine to the ride of the Softail® frame, to inverted front forks and easily adjustable rear suspension, the Fat Bob® 114 is built to shake up the status quo. This is for the rider that wants to break new ground at a high rate of speed.
