supermoto / default rider 183 cm
MZ 125 SM vs MZ Mastiff 660 ergonomics
MZ 125 SM and MZ Mastiff 660 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 MZ 125 SM lists a 830 mm seat; the MZ Mastiff 660 lists 831 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.
