The two bikes are close enough that posture preference matters more than the overall score.
Rider fit: reaching the ground
The Yamaha YZF-R1 has a 856 mm seat; the Yamaha YZF-R1M sits at 861 mm — a 5 mm difference. As a rule of thumb you flat-foot a bike when your inseam roughly matches its seat height: about 86 cm for the Yamaha YZF-R1 and 86 cm for the Yamaha YZF-R1M.
That makes the Yamaha YZF-R1 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 YZF-R1M 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.
