The two bikes are close enough that posture preference matters more than the overall score.
Rider fit: reaching the ground
The BMW C 600 Sport has a 810 mm seat; the Vespa 946 sits at 805 mm — a 5 mm difference. As a rule of thumb you flat-foot a bike when your inseam roughly matches its seat height: about 81 cm for the BMW C 600 Sport and 81 cm for the Vespa 946.
That makes the Vespa 946 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 C 600 Sport 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.
