The two bikes are close enough that posture preference matters more than the overall score.
Rider fit: reaching the ground
The Kawasaki KR-1S has a 755 mm seat; the Yamaha TZR250 sits at 760 mm — a 5 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 KR-1S and 76 cm for the Yamaha TZR250.
That makes the Kawasaki KR-1S 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 TZR250 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.
