Rider fit: reaching the ground
The QJ Motor SRV 550 lists a 785 mm seat; the Royal Enfield Classic 650 lists 800 mm — a 15 mm difference. 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.
