Rider fit: reaching the ground
The GasGas MC 50 has a 653 mm seat; the GasGas MC 65 sits at 730 mm — a 77 mm difference. As a rule of thumb you flat-foot a bike when your inseam roughly matches its seat height: about 65 cm for the GasGas MC 50 and 73 cm for the GasGas MC 65.
That makes the GasGas MC 50 the easier reach to the ground — the safer pick for shorter riders or anyone who wants both feet planted at a stop — while the GasGas MC 65 gives taller riders more legroom and a more open knee bend. Load your own height and inseam into the simulator to see exactly how each one fits you.
