Rider fit: reaching the ground
The Ducati Diavel V4 has a 790 mm seat; the Royal Enfield Classic 650 sits at 800 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 80 cm for the Royal Enfield Classic 650.
That makes the Ducati Diavel V4 the easier reach to the ground — the safer pick for shorter riders or anyone who wants both feet planted at a stop — while the Royal Enfield Classic 650 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.
