Rider fit: reaching the ground

The Kawasaki Vulcan 1500 Mean Streak lists a 701 mm seat; the Triumph Thunderbird Storm lists 700 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.
