naked / default rider 183 cm
Aprilia Mana 850 vs CFMoto 800NK ergonomics
Aprilia Mana 850 and CFMoto 800NK 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 Aprilia Mana 850 lists a 800 mm seat; the CFMoto 800NK lists 800 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 | Aprilia Mana 850 | CFMoto 800NK |

| 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
Aprilia Mana 850 and CFMoto 800NK are both naked bikes, so the practical question is which of their real differences you'd actually feel. CFMoto 800NK is about 48 kg lighter wet than Aprilia Mana 850, which tends to show up most when paddling backward out of a parking spot or picking the bike up off the sidestand. None of that adds up to a clear overall winner in the modeled posture score, so the individual differences above are the more useful comparison than the headline number. Treat every figure here as a planning estimate: seat width, suspension sag, footwear, and your own proportions can shift the real feel more than a few millimetres or degrees on paper. Load your height and inseam into the simulator, then sit on both before you decide.
