standard / default rider 183 cm
Yamaha XS750D vs Yamaha XSR900 ergonomics
Yamaha XS750D and Yamaha XSR900 have modeled posture scores within three points for the 183 cm default rider. Treat this as a planning estimate; posture preference, data confidence, and a real test sit still matter.

The modeled scores are within three points, so the result does not distinguish a higher-scoring bike. Treat the result as a planning estimate and compare each bike's geometry confidence before a real test sit.
Rider fit: reaching the ground
The Yamaha XS750D lists a 813 mm seat; the Yamaha XSR900 lists 810 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.
