moped / default rider 183 cm
Vespa Primavera 50 vs Yamaha Sniper 155 ergonomics
Vespa Primavera 50 and Yamaha Sniper 155 have modeled posture scores within three points for the 183 cm default rider. Treat this as a planning estimate; posture preference, data confidence, and a real test sit still matter.

The modeled scores are within three points, so the result does not distinguish a higher-scoring bike. Treat the result as a planning estimate and compare each bike's geometry confidence before a real test sit.
Rider fit: reaching the ground
The Vespa Primavera 50 lists a 790 mm seat; the Yamaha Sniper 155 lists 795 mm — a 5 mm difference. Seat height is only a first-pass ground-reach input. It does not establish safety or actual foot contact. Seat width, suspension sag, boots, mobility, load, and individual proportions can materially change the result.
On seat height alone, the Vespa Primavera 50 has the easier modeled ground reach. Load your measurements into the simulator to compare the model, then verify both motorcycles in person.
