scooter / default rider 183 cm
Honda ADV350 vs Yamaha XMAX 300 ergonomics
Honda ADV350 and Yamaha XMAX 300 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.
Posture overlay
The default rider's modeled seated posture on each bike, solved from the same geometry as the score panels and overlaid on one ground line so seat height and reach differences are visible at a glance.

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 Honda ADV350 lists a 795 mm seat; the Yamaha XMAX 300 lists 795 mm, within a few millimetres of each other. 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.

Fit by rider height
Modeled ground contact by rider height, in 5 bands from 5'2" to 6'4" (158-193 cm).

| 158 cm / 5'2" | Balls of feet | Balls of feet |
| 167 cm / 5'6" | Balls of feet | Balls of feet |

Modeled from each bike's seat height and a typical inseam-to-height ratio only — not a flat-footing guarantee. Real ground contact still depends on seat shape, suspension sag, footwear, and your own proportions. Confirm on the motorcycle.
Verdict
Honda ADV350 and Yamaha XMAX 300 are both scooter bikes, so the practical question is which of their real differences you'd actually feel. On seat height, wheelbase, wet weight, and the modeled knee, torso-lean, and posture-score deltas, this pair sits inside the range where two bikes fit alike for a given rider — nothing here clears a difference most riders would notice from the saddle. That is a legitimate result, not a missing analysis: some same-category neighbors really are interchangeable on paper. The honest takeaway is to let other factors decide — running costs, service network, styling, availability — because ergonomics alone won't separate Honda ADV350 from Yamaha XMAX 300 for most riders. Load your own height and inseam into the simulator below to see whether your specific proportions turn up a difference the class averages hide, then confirm both bikes in person before you commit.
