When this is the right choice
- 84 N·m at 1.5 kg. EYOU PHU25H-110 needs 2,354 g for the same 84 N·m and Tongchuan TCHL-25 needs 1.85 kg for 83 — this is the lightest frame at that torque in our catalogue.
- 194 N·m start–stop — the same number as PHU25H-110’s instantaneous max, at 63% of the mass.
- 24–80 V covers a 72 V pack, which most harmonic joints do not.
When it is the wrong choice
- Single ratio, and the S parts are thinly documented. Body length and bore are not on our datasheet; confirm the drawing before fixing an envelope.
- No brake and no torque sensor. At 84 N·m this is usually a hip or a large shoulder, and both of those want a brake.
- Figures still being re-verified against the current Ti5 catalogue — 84 N·m at 1.5 kg is a headline number, so we confirm it before quoting.
Alternatives at a similar level
- Ti5 RI100-120-PRO-S — 169 N·m at 2.52 kg — the biggest frame
- Tongchuan TCHL-25 — 83 N·m at 1.85 kg with brake and sensor options
- EYOU PHU25H-110 — 84 N·m with force control, 2,354 g

RI80-97-PRO-S FAQ
How can 84 N·m weigh 1.5 kg?
Thin-wall housing and a compact motor stack, plus the single-ratio build. It is the same reason the S parts exist: less structure for a fixed ratio. We confirm the weight and the drawing on quotation because it is exceptional for the class.
Would you put this on a hip?
Only with a brake added. 84 N·m rated and 194 N·m start–stop fit a small humanoid hip, but a hip that sags on power-off is a safety problem, and no brake is published for this frame.
How long does it take to ship?
Confirmed per order at quotation, together with the specification and drawing confirmation.
