standard / default rider 183 cm
Honda CB400 Super Four vs Honda Grom ABS ergonomics
Honda CB400 Super Four and Honda Grom ABS have modeled posture scores within three points for the 183 cm default rider. Treat this as a planning estimate; posture preference, data confidence, and a real test sit still matter.

The modeled scores are within three points, so the result does not distinguish a higher-scoring bike. Treat the result as a planning estimate and compare each bike's geometry confidence before a real test sit.
Rider fit: reaching the ground
The Honda CB400 Super Four lists a 755 mm seat; the Honda Grom ABS lists 762 mm — a 7 mm difference. Seat height is only a first-pass ground-reach input. It does not establish safety or actual foot contact. Seat width, suspension sag, boots, mobility, load, and individual proportions can materially change the result.
On seat height alone, the Honda CB400 Super Four has the easier modeled ground reach. Load your measurements into the simulator to compare the model, then verify both motorcycles in person.
