The two bikes are close enough that posture preference matters more than the overall score.
Rider fit: reaching the ground
The Kawasaki KX65 has a 760 mm seat; the Yamaha YZ65 sits at 754 mm — a 6 mm difference. As a rule of thumb you flat-foot a bike when your inseam roughly matches its seat height: about 76 cm for the Kawasaki KX65 and 75 cm for the Yamaha YZ65.
That makes the Yamaha YZ65 the easier reach to the ground — the safer pick for shorter riders or anyone who wants both feet planted at a stop — while the Kawasaki KX65 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.
