Rider fit: reaching the ground
The Beta Motor 300 RR Race Edition has a 965 mm seat; the Yamaha YZ125X 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 97 cm for the Beta Motor 300 RR Race Edition and 97 cm for the Yamaha YZ125X.
That makes the Beta Motor 300 RR Race Edition 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 YZ125X gives taller riders more legroom and a more open knee bend.
