cafe-racer / default rider 183 cm
Ducati 250 Mach 1 vs Yamaha SRX400 ergonomics
Ducati 250 Mach 1 and Yamaha SRX400 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 250 Mach 1 lists a 760 mm seat; the Yamaha SRX400 lists 760 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.
