The two bikes are close enough that posture preference matters more than the overall score.
Rider fit: reaching the ground
The KTM 500 MX has a 975 mm seat; the Yamaha YZ250F sits at 970 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 KTM 500 MX and 97 cm for the Yamaha YZ250F.
That makes the Yamaha YZ250F the easier reach to the ground — the safer pick for shorter riders or anyone who wants both feet planted at a stop — while the KTM 500 MX 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.
