The two bikes are close enough that posture preference matters more than the overall score.

Rider fit: reaching the ground

The Bluroc Motorcycles Spirit 125 has a 750 mm seat; the Ducati 900SS sits at 760 mm — a 10 mm difference. As a rule of thumb you flat-foot a bike when your inseam roughly matches its seat height: about 75 cm for the Bluroc Motorcycles Spirit 125 and 76 cm for the Ducati 900SS.

That makes the Bluroc Motorcycles Spirit 125 the easier reach to the ground — the safer pick for shorter riders or anyone who wants both feet planted at a stop — while the Ducati 900SS 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.
