The two bikes are close enough that posture preference matters more than the overall score.
Rider fit: reaching the ground
The Buell XB12S Lightning has a 775 mm seat; the Ducati Monster 900 sits at 770 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 Buell XB12S Lightning and 77 cm for the Ducati Monster 900.
That makes the Ducati Monster 900 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 XB12S Lightning 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.
