sport / default rider 183 cm
Buell 1125R vs Suzuki GSX-R750 ergonomics
Buell 1125R and Suzuki GSX-R750 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 Buell 1125R lists a 775 mm seat; the Suzuki GSX-R750 lists 755 mm — a 20 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 GSX-R750 has the easier modeled ground reach. Load your measurements into the simulator to compare the model, then verify both motorcycles in person.
