Rider fit: reaching the ground
The Harley-Davidson Road King Custom lists a 663 mm seat; the Harley-Davidson Street Glide Special lists 663 mm, within a few millimetres of each other. Seat height is only a first-pass ground-reach input. It does not establish safety or actual foot contact. Seat width, suspension sag, boots, mobility, load, and individual proportions can materially change the result.
