Rider fit: reaching the ground
The Moto Guzzi MGX-21 has a 740 mm seat; the Yamaha Royal Star Venture S sits at 750 mm — a 10 mm difference. As a rule of thumb you flat-foot a bike when your inseam roughly matches its seat height: about 74 cm for the Moto Guzzi MGX-21 and 75 cm for the Yamaha Royal Star Venture S.
That makes the Moto Guzzi MGX-21 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 Royal Star Venture S gives taller riders more legroom and a more open knee bend.
