Rider fit: reaching the ground
The Harley-Davidson Street Bob 114 lists a 680 mm seat; the Kawasaki Vulcan 900 Classic lists 680 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.
