sport / default rider 183 cm
Aprilia RS125 vs Suzuki Hayabusa ergonomics
Aprilia RS125 and Suzuki Hayabusa 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 Aprilia RS125 lists a 805 mm seat; the Suzuki Hayabusa lists 800 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 Suzuki Hayabusa has the easier modeled ground reach. Load your measurements into the simulator to compare the model, then verify both motorcycles in person.
