The two bikes are close enough that posture preference matters more than the overall score.
Rider fit: reaching the ground
The Yamaha XSR125 has a 815 mm seat; the Yamaha XSR900 sits at 810 mm — a 5 mm difference. As a rule of thumb you flat-foot a bike when your inseam roughly matches its seat height: about 82 cm for the Yamaha XSR125 and 81 cm for the Yamaha XSR900.
That makes the Yamaha XSR900 the easier reach to the ground — the safer pick for shorter riders or anyone who wants both feet planted at a stop — while the Yamaha XSR125 gives taller riders more legroom and a more open knee bend. Load your own height and inseam into the simulator to see exactly how each one fits you.
