Rider fit: reaching the ground

The WK Bikes RT 125 Cafe lists a 770 mm seat; the Yamaha SRX600 lists 770 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.
