Rider fit: reaching the ground
The Harley-Davidson Fat Bob 114 lists a 710 mm seat; the Yamaha Road Star lists 710 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.
