Rider Profile

Best ForSuited to riders who have built confidence handling a heavy, low-slung machine at low speeds and in traffic.
PurposeDesigned for relaxed classic-styled cruising and weekend touring rather than outright performance.
Rider FitA tall or strong rider will find it easier to manage the substantial wet weight when maneuvering at a standstill or in parking lots.
CharacterA traditional, heritage-styled cruiser that rewards a laid-back, torque-driven riding style over revs and lean angle.
Not Ideal ForNot a good fit for riders seeking sharp cornering agility, off-road capability, or high-speed sport performance.

2018 Harley-Davidson Softail Herritage Classic Rider Ergonomics Assessment

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

Feet:

At 680mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2018 Harley-Davidson Softail Herritage Classic, 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.
