Rider fit: reaching the ground
The Royal Enfield Classic 650 lists a 800 mm seat; the Zontes 310 V lists 807 mm — a 7 mm difference. 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.
On seat height alone, the Royal Enfield Classic 650 has the easier modeled ground reach. Load your measurements into the simulator to compare the model, then verify both motorcycles in person.
