Rider fit: reaching the ground
The GasGas MC 50 lists a 653 mm seat; the Kawasaki KDX50 lists 480 mm — a 173 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 Kawasaki KDX50 has the easier modeled ground reach. Load your measurements into the simulator to compare the model, then verify both motorcycles in person.
