Rider Profile

Best ForSuits riders with at least some experience handling a heavy, torque-heavy cruiser at low speeds.
PurposeBuilt for muscular, stripped-down street cruising and boulevard presence rather than outright speed or long-distance touring.
Rider FitThe low 690mm seat height is approachable, but the 305kg dry weight demands confident low-speed balance and strength when maneuvering or parking.
CharacterA bold, fat-tired power cruiser with strong low-end torque, aggressive styling, and a commanding, muscular riding presence.
Not Ideal ForNot a good fit for riders wanting sharp cornering agility, off-road capability, or a dedicated long-haul touring setup.

2010 Harley-Davidson FXDF Fat Bob Rider Ergonomics Assessment

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

Feet:

At 690mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2010 Harley-Davidson FXDF Fat Bob, with a cramped knee angle of around 75 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.
