Construction and context

Yonex USA lists HM GRAPHITE, CSR, TUNGSTEN and 2G-Namd™ FLEX FORCE in the product’s material field and supplies named technology labels. These are manufacturer-published construction descriptors; they are not independently tested evidence of a particular feel, shuttle outcome, durability result or player match.

Who it may suit

This record may help a shopper verify the exact ASTROX 88D GAME configuration and compare its listed balance, flex, length, average-weight notation, material labels and stringing field with other catalogued rackets. Product labels do not establish individual fit or results.

Specifications in context

Head Heavy balance
This is Yonex’s published balance label for the cited product and is not treated here as an independently measured handling characteristic.
Medium shaft flex
This manufacturer flex label can help compare listed configurations, but it does not predict personal feel or results.
4U (83 g avg.)
Yonex presents this as an average-weight notation for the cited 4U configuration, not an exact finished-frame measurement.

Tradeoffs and caveats

  • The reviewed Yonex USA listing is specifically 4UG5; check regional listings for any different configuration details.
  • Yonex’s 4U (83 g avg.) notation is an average specification, not a weighed measurement for every individual racquet.
  • The record is for an unstrung racquet, so final setup details depend on string, tension, installation and any grip modification.
