Rider fit: reaching the ground
The Norton Motorcycles Commando 961 Cafe Racer Mk II lists a 813 mm seat; the Yamaha XSR900 lists 810 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.
