KTM 250 SX vs Yamaha YZ125 ergonomics

Rider fit: reaching the ground

The KTM 250 SX has a 925 mm seat; the Yamaha YZ125 sits at 935 mm — a 10 mm difference. As a rule of thumb you flat-foot a bike when your inseam roughly matches its seat height: about 93 cm for the KTM 250 SX and 94 cm for the Yamaha YZ125.

That makes the KTM 250 SX 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.
