Rider Profile

Best ForSuits riders with at least some experience handling a heavy, torque-driven cruiser, though the low seat height keeps it approachable for newer riders too.
PurposeBuilt for stripped-down, stylish street cruising rather than outright speed or long-distance touring.
Rider FitThe low 655mm seat height and manageable dry weight for a big V-twin make it accessible to riders of varying statures, though the wide bars and low-slung stance suit taller riders best for relaxed ergonomics.
CharacterA bare-bones, blacked-out bobber persona with a big air-cooled V-twin rumble, favoring attitude and torque over refinement or high-speed thrills.
Not Ideal ForNot ideal for riders wanting sharp cornering agility, sport-level acceleration, or serious off-road or highway touring comfort.

Rider Fit Visualizer

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

Feet:

At 681mm, a rider of 68.9" with a 31" (estimated) inseam will reach the ground with both feet flat on the 2008 Harley-Davidson FXDB Dyna Street Bob, 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.
