Rider fit: reaching the ground
The Aprilia RSV4 1100 Factory has a 845 mm seat; the Yamaha YZF-R1M sits at 860 mm — a 15 mm difference. As a rule of thumb you flat-foot a bike when your inseam roughly matches its seat height: about 85 cm for the Aprilia RSV4 1100 Factory and 86 cm for the Yamaha YZF-R1M.
