motocross / default rider 183 cm
KTM 350 SX-F vs Yamaha YZ426F ergonomics
KTM 350 SX-F and Yamaha YZ426F 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 KTM 350 SX-F lists a 992 mm seat; the Yamaha YZ426F lists 998 mm — a 6 mm difference. 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.
On seat height alone, the KTM 350 SX-F has the easier modeled ground reach. Load your measurements into the simulator to compare the model, then verify both motorcycles in person.
