Rider fit: reaching the ground
The Ducati Diavel V4 lists a 790 mm seat; the QJ Motor SRV 550 lists 785 mm — a 5 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 QJ Motor SRV 550 has the easier modeled ground reach. Load your measurements into the simulator to compare the model, then verify both motorcycles in person.
