Rider fit: reaching the ground
The Tomos Sprint Sport lists a 780 mm seat; the TVS Motor Rockz 125 lists 780 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.
