Rider fit: reaching the ground
The Fantic XXF 250 has a 970 mm seat; the KTM 500 MX sits at 975 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 Fantic XXF 250 and 98 cm for the KTM 500 MX.
That makes the Fantic XXF 250 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 500 MX 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.
