The two bikes are close enough that posture preference matters more than the overall score.

Rider fit: reaching the ground

The Yamaha YZ125 has a 980 mm seat; the Yamaha YZ250 sits at 975 mm — a 5 mm difference. As a rule of thumb you flat-foot a bike when your inseam roughly matches its seat height: about 98 cm for the Yamaha YZ125 and 98 cm for the Yamaha YZ250.

That makes the Yamaha YZ250 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 YZ125 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.
