Rider fit: reaching the ground
The CZ 400 MX Type 981 has a 836 mm seat; the Kawasaki KX85 sits at 830 mm — a 6 mm difference. As a rule of thumb you flat-foot a bike when your inseam roughly matches its seat height: about 84 cm for the CZ 400 MX Type 981 and 83 cm for the Kawasaki KX85.
That makes the Kawasaki KX85 the easier reach to the ground — the safer pick for shorter riders or anyone who wants both feet planted at a stop — while the CZ 400 MX Type 981 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.
