Rider fit: reaching the ground
The BMW F 800 GS Adventure lists a 890 mm seat; the BMW R 1250 GS Adventure lists 890 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.
