dual-sport / default rider 183 cm
Yamaha XT600E vs Yamaha XT660R ergonomics
Yamaha XT600E and Yamaha XT660R 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 Yamaha XT600E lists a 860 mm seat; the Yamaha XT660R lists 865 mm — a 5 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 Yamaha XT600E has the easier modeled ground reach. Load your measurements into the simulator to compare the model, then verify both motorcycles in person.
