Duora Z-Strike: the Duora that won world titles for Axelsen, Marín and Kobayashi
Three world titles on one frame
Yonex’s own equipment lists put the Duora Z-Strike in the hands of three world champions in four years. In Glasgow in August 2017, Viktor Axelsen beat Lin Dan 22–20, 21–16 for his first world title. In Nanjing a year later, Carolina Marín beat P. V. Sindhu 21–19, 21–10 for her third. In Huelva in December 2021, Yugo Kobayashi played it when he and Takuro Hoki, who used an Astrox 100 ZZ, won Japan’s first men’s doubles world title. The racquet has also outlasted the rest of its family. Yonex released it in February 2017, and in September 2026 its global site still lists the Z-Strike as in stock, the only Duora left in its catalog.
Hyper-MG and the Duora Grommet
Yonex Japan announced the Z-Strike on January 10, 2017 for worldwide release in early February; the Japan-made racquet listed at ¥28,000 before tax. Yonex pitched it at advanced players as a Duora that raised smash and drive performance and added control. Like the Duora 10, its head has a box profile on the forehand face, for smashes, and an aero profile on the backhand face, for drives. Two parts were new. The Duora Grommet is a strip of eight linked grommets at the top of the head, thicker and harder on the aero side, so a forehand meets a stiffer string bed. Hyper-MG, which Yonex called the most elastic carbon it had used, appeared in a Yonex racquet for the first time, in the lower frame to sharpen drives. Yonex lists the frame as extra stiff and 10 mm longer than standard. It has not settled on a balance: Yonex Japan’s gauge leans toward the head, while Yonex USA calls it normal.
Axelsen and Marín
Axelsen first appears on the Z-Strike at the March 2017 All England. That year Yonex lists it for his India Open, World Championships and Japan Open titles, and for his second straight Superseries Finals, won 19–21, 21–19, 21–15 over Lee Chong Wei. In April 2018 he moved to the Astrox 88 S, winning that month’s European title with it, and he was back on the Z-Strike by February 2019, winning the Spain Masters and India Open and losing the All England final to Kento Momota. By the 2020 All England he was on the Astrox 100 ZZ. Marín switched to it from the Nanoray Z-Speed between the March 2017 All England and that year’s India Open. Yonex lists the Z-Strike for her 2017 and 2018 European titles, her first Japan Open in 2017, the 2018 world title and the 2018 China Open. By September 2019 she was on the Nanoflare 700.
One colorway, no player edition
Yonex has listed the Z-Strike in a single black-and-white finish from the 2017 launch to its 2026 global page, in 3U and 2U only. There is no player edition; Axelsen’s first signature racquet was the Astrox 100 VA edition of 2025. Yonex Japan’s 2017 Duora list put the Z-Strike first, ahead of the Duora 10, 7 and 6, and the Duora 8 XP and the lighter Duora 10 LT followed in 2018. Yonex’s 2017 history of its Isometric racquets ended its run of thirteen landmark frames with the Z-Strike, called it the Duora series’ most attacking model and printed Axelsen and Marín beside it. The titles listed under their names include 2016 wins from before the racquet existed: Axelsen’s Superseries Finals, won on the ArcSaber 11, and Marín’s Rio gold, which falls inside her Nanoray Z-Speed years.
Nine years on sale
Verified sales of the Z-Strike so far come from Asia resale and are almost all pre-owned; the price panel above lists them, and the new figure is an estimate. It has an unusual market for a racquet of its age, because Yonex never stopped selling it. In early 2022 Yonex told UK coach Paul Stewart that the whole Duora range was being withdrawn, yet Yonex USA’s Duora page listed only the Z-Strike by March 2023, Yonex Japan’s product page was still live that December, and Yonex’s global site listed it as in stock in September 2026. New frames have been available for most of its life, and most examples were bought to play. Its interest for collectors comes from the titles won with it, which belong to the model rather than to any individual racquet.
What a copy would have to match
No counterfeit of the Z-Strike is documented. That is no guarantee: a frame tied to three world champions and sold new for nine years is an obvious target, and Yonex says fakes are hard to tell from genuine racquets by looks alone. Its construction does give buyers more to examine than most frames. A genuine Z-Strike has two different head profiles, an eight-grommet strip at the top of the head that is thicker on the aero side, and a length 10 mm over standard, and a copy would have to reproduce all of them. Because Yonex has listed only black and white, in 3U and 2U, a Z-Strike in another color or weight class is either mislabeled or not genuine. The callout lists the checks.
A long list of users
Many other Yonex players won with the Z-Strike. Sindhu took the Syed Modi Grand Prix Gold with it on January 29, 2017, days before it reached shops. Lin Dan played it at the May 2017 Sudirman Cup, winning every match in straight games, though Yonex lists him on the Voltric LD-Force at that year’s World Championships. Chou Tien Chen used it from the 2017 World Championships to the 2020 All England final, and Yuta Watanabe won the 2018 All England mixed doubles with it. Satwiksairaj Rankireddy had it when he and Chirag Shetty, on a Voltric 80 E-tune, won the 2019 Thailand Open, the first Superseries or World Tour men’s doubles title for an Indian pair, and again in May 2022 when India won its first Thomas Cup; Yonex’s product page still names him as its player. His 565 km/h Guinness record of April 2023, though, was set with a Nanoflare 1000 Z, not the Z-Strike.
Yonex’s item code is DUO-ZS. It has listed one colorway, black and white, in 3U (average 88 g) or 2U (average 93 g) with G4 or G5 grips; there is no 4U. The frame should be marked Made in Japan, with extra stiff flex. Run a finger around the head: one face should have a squared box profile and the other a slimmer aero profile. At the top of the head, a strip of eight linked grommets should be visibly thicker on the aero side. Yonex lists the frame as 10 mm longer than standard, so compare its length with a regular racquet. Yonex’s own test is the hologram sticker, which is hard to peel on a genuine racquet and lifts easily with a fingernail on a fake, and cone codes should be laser-engraved, not printed.
The Z-Strike is still sold new, so buy on condition and completeness rather than on any idea of scarcity. Its documented history, Axelsen’s 2017 world title, Marín’s 2018 world title and Kobayashi’s 2021 doubles title, belongs to the model, not to a particular frame, and Yonex reports never name a colorway or an individual racquet. Treat match-used claims as unproven without documentation. Stiff frames are often played hard, so ask for daylight photographs of both head profiles, the grommet strip and the T-joint, and look for cracks and repainting.
