The two bikes are close enough that posture preference matters more than the overall score.
Rider fit: reaching the ground
The Suzuki JR50 has a 480 mm seat; the Yamaha PW50 sits at 475 mm — a 5 mm difference. As a rule of thumb you flat-foot a bike when your inseam roughly matches its seat height: about 48 cm for the Suzuki JR50 and 48 cm for the Yamaha PW50.
That makes the Yamaha PW50 the easier reach to the ground — the safer pick for shorter riders or anyone who wants both feet planted at a stop — while the Suzuki JR50 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.
