Rider fit: reaching the ground
The Moto Guzzi MGX-21 lists a 740 mm seat; the Moto Guzzi MGX-21 Flying Fortress lists 739 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.
