Rider fit: reaching the ground

The FB Mondial HPS 300 lists a 790 mm seat; the Mutt Motorcycles Mongrel 125 lists 790 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.
