Rider Profile

Best ForThis bike suits riders who already have some experience handling heavy, low-slung machines at parking-lot speeds and in traffic.
PurposeIt's built for boulevard cruising and making a bold visual statement rather than for outright speed or long-distance touring efficiency.
Rider FitThe very low 670mm seat height makes it accessible for shorter riders, but its substantial 333kg wet weight demands confidence and strength at low speeds and when maneuvering.
CharacterIt delivers a big, torquey V-twin rumble with strong low-end grunt, favoring relaxed, deliberate cruising over aggressive cornering or high-rpm thrills.
Not Ideal ForThis is not the right bike for riders seeking agile canyon carving, off-road capability, or a lightweight, nimble daily commuter.

2013 Harley-Davidson Softail Fat Boy Special Rider Ergonomics Assessment

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

Feet:

At 670mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2013 Harley-Davidson Softail Fat Boy Special, 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.
