Ducati Monster 900 vs Royal Enfield Guerrilla 450 ergonomics
Ducati Monster 900 and Royal Enfield Guerrilla 450 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 Ducati Monster 900 lists a 770 mm seat; the Royal Enfield Guerrilla 450 lists 780 mm — a 10 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 Ducati Monster 900 has the easier modeled ground reach. Load your measurements into the simulator to compare the model, then verify both motorcycles in person.
