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 Harley-Davidson Road King Classic lists a 683 mm seat; the Harley-Davidson Ultra Limited Low lists 675 mm — a 8 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 Harley-Davidson Ultra Limited Low has the easier modeled ground reach. Load your measurements into the simulator to compare the model, then verify both motorcycles in person.
