The two bikes are close enough that posture preference matters more than the overall score.
Rider fit: reaching the ground
The Ducati Diavel V4 has a 790 mm seat; the Honda CB900C Custom sits at 780 mm — a 10 mm difference. As a rule of thumb you flat-foot a bike when your inseam roughly matches its seat height: about 79 cm for the Ducati Diavel V4 and 78 cm for the Honda CB900C Custom.
That makes the Honda CB900C Custom 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 Diavel V4 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.
