Rider Profile

Best ForSuited to riders who are comfortable with a heavy, low-slung cruiser and confident handling significant weight at low speeds.
PurposeBuilt for relaxed boulevard cruising and image-driven riding rather than outright performance or long-distance touring.
Rider FitThe low 616mm seat height and low center of gravity make it accessible to shorter riders, though the 333kg wet weight demands strength when maneuvering at a standstill or on uneven ground.
CharacterA classic fat-tired Harley cruiser that delivers strong low-end torque, a deep V-twin rumble, and unmistakable custom styling over outright speed or agility.
Not Ideal ForNot a good fit for riders seeking sharp cornering ability, off-road capability, or a nimble, lightweight machine for tight urban lane-splitting.

2016 Harley-Davidson Softail Fat Boy Lo Rider Ergonomics Assessment

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

Feet:

At 616mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2016 Harley-Davidson Softail Fat Boy Lo, with a cramped knee angle of around 65 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.
