The two bikes are close enough that posture preference matters more than the overall score.
Rider fit: reaching the ground
The Vespa Primavera RED 50 has a 790 mm seat; the Yamaha Sniper 155 sits at 795 mm — a 5 mm difference. As a rule of thumb you flat-foot a bike when your inseam roughly matches its seat height: about 79 cm for the Vespa Primavera RED 50 and 80 cm for the Yamaha Sniper 155.
That makes the Vespa Primavera RED 50 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 Sniper 155 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.
