The two bikes are close enough that posture preference matters more than the overall score.
Rider fit: reaching the ground
The Kawasaki KX112 has a 866 mm seat; the Yamaha YZ85LW sits at 884 mm — a 18 mm difference. As a rule of thumb you flat-foot a bike when your inseam roughly matches its seat height: about 87 cm for the Kawasaki KX112 and 88 cm for the Yamaha YZ85LW.
That makes the Kawasaki KX112 the easier reach to the ground — the safer pick for shorter riders or anyone who wants both feet planted at a stop — while the Yamaha YZ85LW 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.
