Rider Profile

Best For	Best suited to riders who already have some experience handling heavy, low-slung cruisers at low speed.
Purpose	Built for laid-back boulevard cruising and style-driven weekend rides rather than outright performance.
Rider Fit	Its substantial dry weight and long wheelbase demand confident strength and balance at parking-lot speeds.
Character	A bold, muscular custom cruiser that rewards relaxed throttle-rolling torque over aggressive cornering.
Not Ideal For	Not a good fit for riders seeking sharp handling, off-road capability, or high-speed sport performance.

Units

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 2011 Harley-Davidson FLSTFB 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.
