Rider Profile

Best ForSuits riders from newer intermediate to experienced who want a classic heavyweight cruiser rather than a beginner's first bike.
PurposeBuilt for laid-back boulevard cruising and stylish weekend rides rather than outright performance.
Rider FitLow 648mm seat height makes it approachable for shorter riders, but nearly 305kg wet weight demands confident low-speed handling and strength when maneuvering it off the kickstand or in tight parking.
CharacterA stripped-down, minimalist Softail with bobber styling, deep torque from the Milwaukee-Eight V-twin, and relaxed, low-slung ergonomics that reward smooth, unhurried riding.
Not Ideal ForNot for riders seeking sharp cornering agility, off-road capability, or a light, flickable machine for tight technical roads.

2017 Harley-Davidson Softail Slim Rider Ergonomics Assessment

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

Feet:

At 650mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2017 Harley-Davidson Softail Slim, 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.
