Rider fit: reaching the ground
The Brixton Sunray 125 lists a 790 mm seat; the Norton Motorcycles Commando 750 Fastback lists 788 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.
