The two bikes are close enough that posture preference matters more than the overall score.
Rider fit: reaching the ground
The BMW K 1600 B has a 750 mm seat; the Moto Guzzi MGX-21 sits at 740 mm — a 10 mm difference. As a rule of thumb you flat-foot a bike when your inseam roughly matches its seat height: about 75 cm for the BMW K 1600 B and 74 cm for the Moto Guzzi MGX-21.
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 BMW K 1600 B 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.
