Duora 99: the Duora 88’s stiff, Taiwan-made recipe with titanium mesh, in black
A stiff export Duora with titanium mesh
The Duora 99 is the stiff, Taiwan-made export Duora with titanium mesh in its frame. Yonex lists the frame as H.M. Graphite, Super HMG and Nanometric β with titanium mesh, and the shaft as H.M. Graphite: the Duora 88’s materials with the mesh added, which no other Duora in Yonex’s 2018 or 2021 catalogs lists. It came in one weight, 3U (average 88 g), and one color, Black. Its paper trail is unusual for a Duora: the item code appears in a 2019 catalog, but Yonex gave the racquet a product page only in 2020.
First documented in 2019, pictured in 2020
Yonex USA’s 2019 catalog is the earliest Yonex record. It prints DUO99 in its stringing instructions, in a group with the Z-Strike, 10 LT and 8 XP, but its Duora pages picture only the Z-Strike, 10, 10 LT, 8 XP, 7 and 6. Yonex’s international Duora list never showed a 99 up to January 2020. The first Yonex product page appeared on the rebuilt global site in August 2020. No launch release is known, so 2019 is the year it is first documented, not a launch date. Yonex lists the Dual Optimum System, an Aero+Box frame, an Isometric head, a new grommet pattern, a built-in T-joint, the Control Support Cap and a slim shaft, and the frame is 10 mm longer than standard.
No player on the 99
Yonex named no player for the Duora 99, and no Yonex source documents a professional using it. Yonex UK’s page carries only the series pitch, “Huge forehands. Quick backhands. The DUORA lets players do both with one revolutionary design.” The Duora players Yonex documented used other models, such as the Duora 10, 7 and Z-Strike, which have their own pages.
One code, one color
Every Yonex page for the 99 shows one item code, DUO99, and one color, Black: the international pages of 2020 to 2023, Yonex USA’s 2021 catalog and Yonex UK’s page of May 2022. No player or limited edition is documented. Yonex’s international pages list G4 and G5 grips, the 2021 catalog G5 and Yonex UK G4, with Yonex UK giving the 3U range as 85–89.9 g. The Duora 9 (DUO9) is not a lighter version of the 99 but a different frame, a Magenta, Japan-made 4U racquet of 2018; it has its own page.
On the global list to early 2023
The 99 was an export model, and no Yonex Japan listing of it is known. Yonex USA’s 2021 catalog priced it at $195, below the $245 Duora 6 and the $270 Duora 10 on the same pages. Yonex’s rebuilt global Duora list carried it from September 2020; by September 2021 the list had shrunk to seven models, the 99 among them, and it was still listed in January 2023, with its product page showing it in stock on 1 February. By late March 2023 only the Z-Strike remained. Yonex published no production-end notice, so 2023 is the last year the 99 is documented on sale. No verified sales are recorded yet.
The Duora 88 look-alike
No counterfeit of the Duora 99 is documented, and Yonex published no guide specific to it. The likelier mix-up is the Duora 88: also stiff, Taiwan-made and 3U with an H.M. Graphite shaft, but without titanium mesh, and Yonex recommended 19–26 lb for it against 21–29 lb for the 99. The Duora 77 shares the Taiwan origin and 3U weight but is rated Medium, and the Japan-made Duoras such as the 10, 7 and Z-Strike carry a Japan marking. The Astrox 99 shares only the number.
A late branch of the export Duoras
In the Duora story the 99 is a late addition: the stiff export Duora that stayed on Yonex’s global list after the 88, 55 and 77 had gone, and one of the seven Duoras still listed when the range was cut back to the Z-Strike in 2023. With no player, launch or Japanese release behind it, it is documented mainly by its spec pages. For a collector it joins the Taiwan-made export set of the 88, 77, 55 and 33. The Duora 10 page tells how the series wound down.
Yonex’s item code is DUO99. Yonex listed it only in 3U (average 88 g; Yonex UK: 85–89.9 g) with G4 or G5 grips, rated it Stiff and recommends 21–29 lb. The frame is 10 mm longer than standard, and Black is the only Yonex color. Yonex UK gives Taiwan as the place of manufacture, so a Japan marking points to a Japan-made Duora such as the 10 or 7, and a 4U label to another Duora such as the 9. Check that the head shows the two profiles Yonex calls Aero+Box, and that the model name reads 99, not 88 or 9.
Judge a Duora 99 on condition and completeness rather than scarcity: Yonex listed it on its global site for about two and a half years in one color. Confirm the DUO99 code, the 3U label, the black finish and a Taiwan marking, and tell it apart from the Duora 88, which shares its flex, weight and origin. Ask for daylight photographs of both head faces, the T-joint and the cone, and look for cracks and repainting.
