Rider fit: reaching the ground
The Kawasaki KZ650 B1 lists a 810 mm seat; the Triumph Speed Twin 1200 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.
