Rider Profile

Best ForSuited to riders who already have some experience handling a heavy, torque-heavy cruiser at low speeds.
PurposeBuilt for strong straight-line torque, muscular styling, and boulevard cruising rather than outright top-end speed or cornering agility.
Rider FitThe low seat height helps shorter riders, but the substantial wet weight and wide handlebars demand decent upper-body strength at parking-lot speeds.
CharacterA bold, muscular power-cruiser persona with fat tires and drag-style attitude that rewards relaxed, confident throttle-heavy riding.
Not Ideal ForNot a good fit for riders seeking nimble cornering, long-distance touring comfort, or any off-road capability.

2018 Harley-Davidson Softail 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 2018 Harley-Davidson Softail 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.
