Rider Profile

Best ForSuited to intermediate and experienced riders comfortable managing 300+ kg of low-slung muscle; the low seat helps but the weight demands respect at low speed.
PurposeBoulevard cruising and relaxed highway miles with unmistakable presence - built for torquey, straight-line style rather than speed or agility.
Rider FitVery low 658mm seat, forward controls, wide pulled-back bars and a massive 240-section rear tire; heavy but planted, with feet-forward relaxed ergonomics.
CharacterIconic solid-wheel Harley muscle cruiser: huge torque from the Milwaukee-Eight 114, deep exhaust rumble, all about attitude and effortless low-rev thrust.
Not Ideal ForNot for sport riders, twisty-road chargers, off-road use, or beginners intimidated by heavy machines; poor at nimble maneuvering and spirited cornering.

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

Feet:

At 658mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2023 Harley-Davidson Fat Boy 114, with a cramped knee angle of around 70 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.
