Rider Profile

Best ForBest suited to riders with at least some prior motorcycle experience, given the fat rear tire, low seat height, and heavy custom-cruiser handling characteristics.
PurposeBuilt for stylish street cruising and short blasts rather than outright speed or long-distance touring.
Rider FitThe very low seat height and moderate weight make it manageable for shorter riders, though the wide 240mm rear tire adds some effort to low-speed maneuvering.
CharacterA muscular, aggressive-looking cruiser with strong torque delivery low in the rev range that rewards relaxed, punchy riding over corner-carving precision.
Not Ideal ForNot a good fit for riders wanting off-road capability, aggressive sport handling, or a plush long-haul touring platform.

2020 Harley-Davidson Fat Bob 114 Rider Ergonomics Assessment

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

Feet:

At 710mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2020 Harley-Davidson Fat Bob 114, with a cramped knee angle of around 80 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.
