electric / default rider 183 cm
Arc Vehicle Vector vs Zero Motorcycles XB ergonomics
Arc Vehicle Vector and Zero Motorcycles XB 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 Arc Vehicle Vector lists a 825 mm seat; the Zero Motorcycles XB lists 832 mm — a 7 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 Arc Vehicle Vector has the easier modeled ground reach. Load your measurements into the simulator to compare the model, then verify both motorcycles in person.
