Rider fit: reaching the ground
The Piaggio NRG Power 50 DD 2T lists a 785 mm seat; the Vespa Primavera RED 50 lists 785 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.
