supermoto / default rider 183 cm
GasGas SM 125 Halley vs Kreidler Supermoto 50 DD ergonomics
GasGas SM 125 Halley and Kreidler Supermoto 50 DD 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 GasGas SM 125 Halley lists a 870 mm seat; the Kreidler Supermoto 50 DD lists 870 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.
