Duora 9: the Duora 10’s materials in a 4U, Magenta, Japan-made export frame
A lighter frame on the Duora 10’s materials
The Duora 9 put the Duora 10’s materials into a lighter frame. Yonex’s 2018 catalog lists both with the same H.M. Graphite, Nanometric DR and nickel-titanium fiber frame, an H.M. Graphite and Nanometric shaft and a Stiff rating, but the 9 came only in 4U (average 83 g) and in Magenta, where the 10 was sold in 3U and 2U. It was made in Japan, yet Yonex Japan’s own Duora range of June 2018 did not include it: the 9 was sold through Yonex’s international site and catalogs. Yonex published no launch release for it and named no player.
Two faces and a space-age carbon
Yonex’s international Duora list showed eight models from January to mid-March 2018 and ten on 30 March, with the 9 and the Duora 33 added; no earlier Yonex record of the 9 is known. Its pages list the Dual Optimum System, the two-sided Duora concept that Yonex summed up as “Huge forehands. Quick backhands.”, with an Aero+Box frame, an Isometric head, a new grommet pattern, Solid Feel Core, a new built-in T-joint, a Super Slim Long Shaft and the Control Support Cap. Yonex described Nanometric DR as a carbon developed from a Toray material “originally developed for next generation space aviation”, and wrote that “by combining firm shuttle hold and high repulsion, NANOMETRIC DR puts the DUORA into a class of its own.” The frame is 10 mm longer than standard.
No player on the 9
Yonex named no player for the Duora 9, and no Yonex source documents a professional using it. The only player on its pages is Lee Chong Wei, in the quote Yonex ran across the Duora range: “I feel like my arm is one with the racquet on both my forehand and backhand, so I can push faster at the net.” That line sells the series, not the 9. Lee’s documented Duora is the Duora 10, which has its own page.
One code, one color
Yonex sold the 9 under one item code, DUO9, in one documented color, Magenta: on its international pages of 2018 and 2020, in its 2018 catalog, on Yonex UK’s page of November 2018 and on Yonex USA’s page of November 2019. No player, limited or Lee Chong Wei edition was made. Yonex’s international page offered G4, G5 and G6 grips; Yonex UK listed G4 and gave the 4U range as 80–84.9 g. The near-namesake Duora 99 (DUO99) is a different racquet, a black, Taiwan-made 3U frame with titanium mesh first documented in 2019; it has its own page.
Two and a half years on export lists
The Duora 9 was an export model. Yonex’s international Duora list carried it from March 2018 to January 2020, and Yonex USA’s 2019 catalog names DUO9 only in its stringing instructions, not among the Duoras it pictured. When Yonex rebuilt its global site in 2020, the 9 was shown in stock in August and was on the new Duora list of September 2020; the next list on record, of September 2021, had dropped it along with the 6, 77 and 8 XP. Yonex USA’s 2021 catalog does not name it. Yonex published no production-end notice, so 2020 is the last year it is documented on sale. No verified sales are recorded yet.
Copies and look-alikes
No counterfeit of the Duora 9 is documented, and Yonex published no guide specific to it. Mix-ups within the family are the likelier problem, since every Duora shares the two-profile head and the long frame. The Duora 10 LT is the closest look-alike: also Japan-made, 4U and rated Stiff, but with Vibslayer Carbon in place of nickel-titanium fiber and a Pink/Yellow finish. The Duora 6 is Japan-made and 4U too, but Hi-Flex. The Duora 10 shares the 9’s material list but was never listed in 4U, and the export 88, 77, 55 and 33 were made in Taiwan.
A side branch of the Japan-made Duoras
In the Duora story the 9 is a short side branch: a Japan-made, Stiff 4U frame on the Duora 10’s materials, added to the export range in spring 2018 and gone from Yonex’s list by September 2021. With no player, edition or Japanese release behind it, it is less documented than the Japan-market Duoras. For a collector it rounds out the Japan-made 4U Duoras with the 6 and the 10 LT. The Duora 10 page tells how the series wound down.
Yonex’s item code is DUO9. Yonex listed it only in 4U (average 83 g; Yonex UK: 80–84.9 g) with G4, G5 or G6 grips, rated it Stiff and recommends 19–26 lb. The frame is 10 mm longer than standard, and the only Yonex color is Magenta. Yonex lists it as made in Japan, so a Taiwan marking, or a 3U or 2U label, points to another Duora. Check that the head shows the two profiles Yonex calls Aero+Box, and that the model name is the 9, not the 99 or the 10.
Judge a Duora 9 on condition and completeness rather than scarcity: Yonex listed it for about two and a half years in one color. Confirm the DUO9 code, a 4U label, the Magenta finish and a Japan marking, since the 10 LT and 6 share its weight and origin. Ask for daylight photographs of both head faces, the T-joint and the cone, and look for cracks and repainting.
