Rider fit: reaching the ground
The GasGas MC 50 lists a 653 mm seat; the Yamaha PW50 lists 475 mm — a 178 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 Yamaha PW50 has the easier modeled ground reach. Load your measurements into the simulator to compare the model, then verify both motorcycles in person.
