Rider fit: reaching the ground
The Beta Motor RR X-Pro 4T 350 lists a 930 mm seat; the Rieju MR Ranger 300 lists 928 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.
