Rider Profile

Best ForThis bike suits riders who have at least some experience handling a heavy, low-slung cruiser at low speeds.
PurposeIt's built for relaxed, torque-driven cruising and stylish around-town riding rather than outright speed or sport handling.
Rider FitThe low 655mm seat height makes it approachable for shorter riders, though its nearly 300kg weight demands confident low-speed control.
CharacterIt delivers classic Harley-Davidson soul with strong low-end torque, a stripped-down custom silhouette, and an easygoing, laid-back riding character.
Not Ideal ForIt's not the right choice for riders seeking sharp cornering agility, off-road capability, or long-distance touring comfort.

2021 Harley-Davidson Softail Standard Rider Ergonomics Assessment

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

Feet:

At 655mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2021 Harley-Davidson Softail Standard, 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.
