The two bikes are close enough that posture preference matters more than the overall score.
Rider fit: reaching the ground
The Aprilia RS125 has a 805 mm seat; the Suzuki Hayabusa 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 Aprilia RS125 and 80 cm for the Suzuki Hayabusa.
That makes the Suzuki Hayabusa the easier reach to the ground — the safer pick for shorter riders or anyone who wants both feet planted at a stop — while the Aprilia RS125 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.
