Rider fit: reaching the ground
The Rieju MRT 125 SM AC lists a 870 mm seat; the Rieju MRT 125 SM LC lists 870 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.
