scrambler / default rider 183 cm
Zontes 125 G1 vs Zontes 350 GK ergonomics
Zontes 125 G1 and Zontes 350 GK 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 Zontes 125 G1 lists a 795 mm seat; the Zontes 350 GK 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).
| Rider height | Zontes 125 G1 | Zontes 350 GK |
|---|---|---|
| 158 cm / 5'2" | Balls of feet | Balls of feet |
| 167 cm / 5'6" | Balls of feet | Balls of feet |
| 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
Zontes 125 G1 and Zontes 350 GK are both scrambler 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 Zontes 125 G1 from Zontes 350 GK 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.
