Astrox 88 S: the front-court racquet behind Kevin Sukamuljo’s 2018 and 2019 titles
Kevin’s racquet, Lee Yong-dae’s brief
For two seasons the Astrox 88 S was the racquet in Kevin Sanjaya Sukamuljo’s hand. Yonex lists him on it from the March 2018 All England, where he and Marcus Fernaldi Gideon beat Mathias Boe and Carsten Mogensen 21–18, 21–17 for a second straight title, to the 2020 All England final. Yonex counted eight World Tour titles for the pair in 2018 and kept listing the 88 S through their 2019 wins. It is often described as a racquet built around Kevin’s hand speed. Yonex tells it differently. It developed the 88 S and 88 D with advice from Lee Yong-dae, the Korean former men’s doubles world No. 1 and Beijing 2008 mixed doubles gold medalist, for front- and back-court players in general, and Kevin had won all of the pair’s 2017 titles on an ArcSaber 11.
Skill, and five extra millimeters
Yonex Japan announced the pair on January 16, 2018 for worldwide release in mid-March, at ¥25,000 before tax each, made in Japan. Its doubles logic was that the back-court player breaks the opponents down and the front-court player turns the openings into points; the S stands for Skill. Where the 88 D flexes mainly in the upper frame, the 88 S bends along the whole frame to hold the shuttle for control and finishing accuracy, and it was the first Yonex frame made 5 mm longer than standard, which Yonex said combined handling with power. Namd is in the shaft only, a new Energy Boost Cap lets the shaft flex while resisting twist, and the Rotational Generator System came from the Astrox 77. Yonex rates it stiff, its Japanese gauge puts the balance on the head-heavy side, and its swing-robot test credited the 88 S with 3.1% more smash power, against 5.4% for the 88 D.
Kevin, Axelsen and Lee Yong-dae
Mathias Boe used the 88 S before it reached shops, winning the Swiss Open with Mogensen in February 2018. Kevin was still on the ArcSaber 11 at the pair’s January and February 2018 titles, and Yonex Japan’s preview said they would take up the Astrox 88 at the All England. With Kevin on the 88 S they won their first Indonesia Open and the Denmark Open in 2018, and in 2019 a third straight Japan Open and the French Open, their seventh title of that season. Viktor Axelsen began using it at the April 2018 European Championships, his first event back from injury, and won the final 21–8, 21–7 in 31 minutes. He said he liked how the shaft stayed firm on compact swings and flexed on big ones. He lost the July 2018 Indonesia Open final to Kento Momota’s 88 D and was back on the Duora Z-Strike by February 2019. Lee Yong-dae played the 88 S himself, winning the 2018 Spain Masters with Kim Gi-jung.
Emerald Green and Off-White/Red
Emerald Green was the launch finish, with the 88 D in Ruby Red. In May 2020 Yonex gave both a linked red, black and off-white design under the same codes, and said Kevin and Gideon, Keigo Sonoda and Takeshi Kamura, and Yuki Fukushima and Sayaka Hirota would adopt it. Yonex’s reports never name a colorway, so neither finish can be tied to a particular title. The second-generation 88 S Pro of March 2021 is a different racquet, with Volume Cut Resin, and it is the 88 S Pro that Yonex lists for Kevin by late 2021. A third generation followed in 2024, and its Pro and Game versions have their own pages.
Three years in Yonex’s range
The verified sales in the price panel above are pre-owned first-generation frames from the Asian resale market; the 2021 88 S Pro and the 2024 Pro and Game have their own pages. Yonex Japan sold the first generation from March 2018 until the turn of 2021, when its Astrox list replaced the 88 S and 88 D with Pro and Game models, and Yonex USA still carried the Off-White/Red in its 2021 catalog. Its Japanese launch price was ¥25,000 before tax. Both finishes share one code and one specification. The model’s interest rests on Kevin and Gideon’s 2018 and 2019 seasons, on Axelsen’s brief spell with it and on Lee Yong-dae’s part in its design. That record belongs to the model, not to any individual frame.
Three generations under one name
No counterfeit of the first-generation 88 S is documented, though popular pro frames attract counterfeiters and Yonex says fakes are hard to spot by looks alone. The likelier trap is the name. Yonex has sold three generations of Astrox 88 S, in 2018, 2021 and 2024, and the later two came in several tiers; the 2024 88 S Game, for example, is made in Taiwan. A listing can pair photographs of one generation with the description of another. The 88 D is a second trap, because it shares the 88 S’s frame materials and differs mainly in color, flex pattern and length. The callout lists the checks.
The first of three generations
The 88 S and 88 D were not Yonex’s first doubles pair. In 2004 it split the Armortec 800 into Offensive and Defensive models, by attack and defense rather than by court position, and it has not linked the two pairs. The 88 idea has lasted longer. In January 2021 Yonex called the originals “popular doubles-concept racquets” as it announced the Pro versions, and its 2024 generation keeps the 88 S 5 mm longer than standard and the 88 D 10 mm longer. Women’s pairs won with the first 88 S too: Wakana Nagahara used it when she and Mayu Matsumoto retained their world title in 2019. A 2018 reviewer found it the lighter-headed of the pair and called it a playmaker’s racquet, though Yonex’s own gauge still places it on the head-heavy side.
Yonex’s item code is AX88S. The first generation came in Emerald Green (2018) or Off-White/Red (2020), and both should be marked Made in Japan; a frame made anywhere else is not a first-generation 88 S. Yonex lists stiff flex, 4U (average 83 g) or 3U (average 88 g) with G4 or G5 grips, and a frame 5 mm longer than standard; the 88 D is 10 mm longer. Materials are high-modulus graphite with Nanometric and tungsten in the frame and Namd in the shaft, with the Energy Boost Cap, and any mention of Volume Cut Resin points to the 2021 88 S Pro. Yonex’s own test is the hologram sticker, which resists peeling on a genuine racquet and lifts easily with a fingernail on a fake, and cone codes should be laser-engraved, not printed.
Buy the first-generation 88 S on condition and identity. Ask for daylight photographs of the whole frame, the cone and the shaft markings, and confirm the finish, the Made in Japan marking and the absence of later-generation technology. Kevin’s and Axelsen’s use belongs to the model, and Yonex never named a colorway for any match, so treat claims that a frame is “Kevin’s Emerald Green” or match-used as unproven without documentation. Players who want the same idea today will find it in later 88 S generations, which are different racquets.
