Rider Profile

Best ForBest for intermediate to experienced riders comfortable managing 800+ lbs of low-slung weight; not a beginner's first bike due to sheer mass.
PurposeA stripped-down bagger built for relaxed long-haul highway cruising and open-road touring with saddlebags, windshield and cruise control.
Rider FitLow 27.4in seat and forward controls give a laid-back stance; very heavy at 820 lbs wet, but weight carries low for planted feel once rolling.
CharacterClassic American V-twin muscle: massive 165Nm torque from the Milwaukee-Eight 114, effortless roll-on, and a commanding, nostalgic road presence.
Not Ideal ForNot for off-road, tight-corner sport riding, track days, or riders wanting a light, flickable machine for stop-and-go city commuting.

2020 Harley-Davidson Road King Special Rider Ergonomics Assessment

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

Feet:

At 695mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2020 Harley-Davidson Road King Special, 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.
