sport-touring / default rider 183 cm
Ducati ST4S vs Kawasaki Ninja 1000SX ergonomics
Ducati ST4S and Kawasaki Ninja 1000SX 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 ST4S lists a 820 mm seat; the Kawasaki Ninja 1000SX lists 820 mm, within a few millimetres of each other. 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.
