Rider fit: reaching the ground
The Aprilia Dorsoduro 900 lists a 864 mm seat; the Derbi Senda DRD X-Treme 50 SM lists 865 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.
