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 Derbi Senda X-Race 50 SM lists a 850 mm seat; the Husqvarna Motorcycles SM 570 R lists 845 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 Husqvarna Motorcycles SM 570 R has the easier modeled ground reach. Load your measurements into the simulator to compare the model, then verify both motorcycles in person.
