Sherco 250 SEF Factory vs Sherco 450 SEF-R ergonomics

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 Sherco 250 SEF Factory lists a 950 mm seat; the Sherco 450 SEF-R lists 950 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.
