The two bikes are close enough that posture preference matters more than the overall score.
Rider fit: reaching the ground
The BMW C 650 GT has a 805 mm seat; the Yamaha XMAX 400 sits at 800 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 650 GT and 80 cm for the Yamaha XMAX 400.
That makes the Yamaha XMAX 400 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 650 GT 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.
