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 BMW R 1200 GS Adventure lists a 895 mm seat; the KTM 640 LC4 Adventure lists 945 mm — a 50 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 BMW R 1200 GS Adventure has the easier modeled ground reach. Load your measurements into the simulator to compare the model, then verify both motorcycles in person.
