The two bikes are close enough that posture preference matters more than the overall score.
Rider fit: reaching the ground
The Buell 1125R has a 775 mm seat; the Yamaha TZR250 sits at 760 mm — a 15 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 Buell 1125R and 76 cm for the Yamaha TZR250.
That makes the Yamaha TZR250 the easier reach to the ground — the safer pick for shorter riders or anyone who wants both feet planted at a stop — while the Buell 1125R 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.
