Rider Profile

Best ForSuited to riders who have already built confidence handling a heavy machine at low speed, since the Fat Boy Special's mass demands deliberate, unhurried inputs.
PurposeBuilt for style-driven boulevard cruising and weekend rides where presence and sound matter as much as outright performance.
Rider FitIts low seat height is approachable but the substantial curb weight means shorter or less physically strong riders may find slow maneuvers and parking lot U-turns demanding.
CharacterA classic American cruiser character defined by big-twin torque, a commanding fat-tired stance, and relaxed, unhurried acceleration rather than outright speed.
Not Ideal ForNot a good fit for riders seeking agile cornering, off-road capability, or lightweight everyday commuting.

2017 Harley-Davidson Fat Boy Special Rider Ergonomics Assessment

Calculated in your browser only - your height/inseam are never sent to our servers.

Feet:

At 660mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2017 Harley-Davidson Fat Boy Special, with a cramped knee angle of around 70 degrees and an upright riding position.

Data quality: measured. Assumes about 30mm of suspension sag once seated (a typical street-bike rule of thumb - stiffer or softer suspension will vary). This is an approximation from category-typical geometry and generic body proportions, not a measurement of this specific bike or you - sit on it before you buy.
