Rider fit: reaching the ground
The Yamaha XS1100 lists a 820 mm seat; the Yamaha XSR900 lists 815 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 Yamaha XSR900 has the easier modeled ground reach. Load your measurements into the simulator to compare the model, then verify both motorcycles in person.
