Yamaha WR250F vs Yamaha WR400F ergonomics

Rider fit: reaching the ground

The Yamaha WR250F has a 998 mm seat; the Yamaha WR400F sits at 991 mm — a 7 mm difference. As a rule of thumb you flat-foot a bike when your inseam roughly matches its seat height: about 100 cm for the Yamaha WR250F and 99 cm for the Yamaha WR400F.

That makes the Yamaha WR400F 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 WR250F 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.
