Rider fit: reaching the ground
The KTM 690 SMC R has a 925 mm seat; the Yamaha WR125X sits at 920 mm — a 5 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 690 SMC R and 92 cm for the Yamaha WR125X.
That makes the Yamaha WR125X 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 690 SMC R 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.
