Rider Profile

Best ForSuitable for beginner to intermediate riders who want a manageable, low-slung cruiser with classic V-twin character.
PurposeBuilt for short blasts, boulevard cruising, and style-focused riding rather than outright speed or long-distance touring.
Rider FitVery low seat height and low center of gravity make it easy for shorter riders to handle, though limited ground clearance and suspension travel require a relaxed, upright riding style.
CharacterA stripped-down, fat-tired custom cruiser that delivers punchy low-end torque, a thumping air-cooled V-twin soundtrack, and bold Dark Custom styling.
Not Ideal ForNot a good fit for riders seeking sport-bike agility, off-road capability, or a comfortable two-up long-distance tourer.

2017 Harley-Davidson Sportster Forty-Eight 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 2017 Harley-Davidson Sportster Forty-Eight, 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.
