Rider fit: reaching the ground
The Moto Morini Calibro has a 725 mm seat; the QJ Motor SRV 600 V4 sits at 720 mm — a 5 mm difference. As a rule of thumb you flat-foot a bike when your inseam roughly matches its seat height: about 73 cm for the Moto Morini Calibro and 72 cm for the QJ Motor SRV 600 V4.
