Honda CB400 Super Four vs Honda Grom ergonomics

Rider fit: reaching the ground

The Honda CB400 Super Four has a 755 mm seat; the Honda Grom sits at 761 mm — a 6 mm difference. As a rule of thumb you flat-foot a bike when your inseam roughly matches its seat height: about 76 cm for the Honda CB400 Super Four and 76 cm for the Honda Grom.

That makes the Honda CB400 Super Four the easier reach to the ground — the safer pick for shorter riders or anyone who wants both feet planted at a stop — while the Honda Grom 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.
