Rider Profile

Best ForBest suited to riders who already have experience handling heavy, low-slung cruisers at low speeds and in traffic.
PurposeBuilt for relaxed boulevard cruising and image-driven riding rather than outright speed or cornering performance.
Rider FitIts low seat height is approachable, but the substantial dry weight demands confident low-speed balance and upper-body strength when maneuvering at a standstill.
CharacterA classic fat-tired Harley custom that delivers deep V-twin torque and presence over agility, rewarding a laid-back, unhurried riding style.
Not Ideal ForNot a good fit for riders seeking sharp handling, high-speed touring comfort, or any off-road capability.

2010 Harley-Davidson FLSTFB Sportster Fat Boy Special Rider Ergonomics Assessment

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

Feet:

At 680mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2010 Harley-Davidson FLSTFB Sportster 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.
