Rider fit: reaching the ground
The Harley-Davidson Low Rider S lists a 720 mm seat; the QJ Motor SRV 600 V4 lists 720 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.
