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 Honda Today lists a 703 mm seat; the Yamaha LB 70 Chappy lists 710 mm — a 7 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 Honda Today has the easier modeled ground reach. Load your measurements into the simulator to compare the model, then verify both motorcycles in person.
