scooter / default rider 183 cm
Honda Spree vs Yamaha Jog CE50 ergonomics
Honda Spree and Yamaha Jog CE50 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 Spree lists a 700 mm seat; the Yamaha Jog CE50 lists 690 mm — a 10 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 Jog CE50 has the easier modeled ground reach. Load your measurements into the simulator to compare the model, then verify both motorcycles in person.

Fit by rider height
Modeled ground contact by rider height, in 5 bands from 5'2" to 6'4" (158-193 cm).
| Rider height | Honda Spree | Yamaha Jog CE50 |
|---|---|---|
| 158 cm / 5'2" | Both feet flat | Both feet flat |
| 167 cm / 5'6" | Both feet flat | Both feet flat |
| 176 cm / 5'9" | Both feet flat | Both feet flat |
| 184 cm / 6'0" | Both feet flat | Both feet flat |
| 193 cm / 6'4" | Both feet flat | Both feet flat |
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 Spree and Yamaha Jog CE50 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 Spree from Yamaha Jog CE50 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.
