The two bikes are close enough that posture preference matters more than the overall score.
Rider fit: reaching the ground
The Honda CB-1 has a 775 mm seat; the Kawasaki Z125 Pro sits at 780 mm — a 5 mm difference. As a rule of thumb you flat-foot a bike when your inseam roughly matches its seat height: about 78 cm for the Honda CB-1 and 78 cm for the Kawasaki Z125 Pro.
That makes the Honda CB-1 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 Z125 Pro 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.
