The two bikes are close enough that posture preference matters more than the overall score.
Rider fit: reaching the ground
The BMW F800S has a 840 mm seat; the Yamaha YZF-R7 sits at 835 mm — a 5 mm difference. As a rule of thumb you flat-foot a bike when your inseam roughly matches its seat height: about 84 cm for the BMW F800S and 84 cm for the Yamaha YZF-R7.
That makes the Yamaha YZF-R7 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 F800S 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.
