KTM 50 SX Factory Edition vs Yamaha PW50 ergonomics

Rider fit: reaching the ground

The KTM 50 SX Factory Edition has a 653 mm seat; the Yamaha PW50 sits at 475 mm — a 178 mm difference. As a rule of thumb you flat-foot a bike when your inseam roughly matches its seat height: about 65 cm for the KTM 50 SX Factory Edition and 48 cm for the Yamaha PW50.

That makes the Yamaha PW50 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 50 SX Factory Edition 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.
