Rider Profile

Best ForSuits riders from newer to experienced who want a low, easygoing cruiser rather than a bike that demands advanced skill.
PurposeBuilt for laid-back boulevard cruising and style-focused short rides rather than outright performance or distance-eating touring.
Rider FitThe very low seat height and low center of gravity make it accessible to shorter riders, though the fat front tire and stretched-out cruiser geometry add some effort in slow-speed maneuvers.
CharacterA classic blacked-out custom cruiser with punchy low-end V-twin torque, deep exhaust note, and a relaxed, chopper-inspired stance meant to be seen as much as ridden hard.
Not Ideal ForNot the right choice for riders wanting sharp cornering agility, high-speed touring comfort, or any off-road capability.

2015 Harley-Davidson Sportster Seventy-Two Dark Custom Rider Ergonomics Assessment

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

Feet:

At 710mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2015 Harley-Davidson Sportster Seventy-Two Dark Custom, 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.
