Rider fit: reaching the ground
The Maico 490 Sand Spider has a 1010 mm seat; the Yamaha YZ125 sits at 998 mm — a 12 mm difference. As a rule of thumb you flat-foot a bike when your inseam roughly matches its seat height: about 101 cm for the Maico 490 Sand Spider and 100 cm for the Yamaha YZ125.
That makes the Yamaha YZ125 the easier reach to the ground — the safer pick for shorter riders or anyone who wants both feet planted at a stop — while the Maico 490 Sand Spider gives taller riders more legroom and a more open knee bend.
