The two bikes are close enough that posture preference matters more than the overall score.
Rider fit: reaching the ground
The Ural Gear Up Forest has a 813 mm seat; the Yamaha NIKEN sits at 820 mm — a 7 mm difference. As a rule of thumb you flat-foot a bike when your inseam roughly matches its seat height: about 81 cm for the Ural Gear Up Forest and 82 cm for the Yamaha NIKEN.
That makes the Ural Gear Up Forest 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 NIKEN 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.
