Rider fit: reaching the ground
The Aprilia Dorsoduro 1200 lists a 870 mm seat; the Beta Motor M4 Motard 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.
