Rider fit: reaching the ground
The BMW G 650 Xchallenge has a 909 mm seat; the Fantic XEF 250 Trail sits at 915 mm — a 6 mm difference. As a rule of thumb you flat-foot a bike when your inseam roughly matches its seat height: about 91 cm for the BMW G 650 Xchallenge and 92 cm for the Fantic XEF 250 Trail.
That makes the BMW G 650 Xchallenge the easier reach to the ground — the safer pick for shorter riders or anyone who wants both feet planted at a stop — while the Fantic XEF 250 Trail gives taller riders more legroom and a more open knee bend.
