sport-touring / default rider 183 cm
CFMoto 650TK vs Yamaha TDM850 ergonomics
CFMoto 650TK and Yamaha TDM850 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 CFMoto 650TK lists a 795 mm seat; the Yamaha TDM850 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).

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
CFMoto 650TK and Yamaha TDM850 are both sport-touring bikes, so the practical question is which of their real differences you'd actually feel. Yamaha TDM850 runs a 60 mm longer wheelbase than CFMoto 650TK, which typically trades some low-speed agility for extra stability at speed. 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.
