Overview

Yonex USA identifies the ASTROX 88S GAME as an unstrung badminton racquet. Its current product page lists 4UG5, a 4U (83 g avg.) notation, medium shaft flex, a 5 mm-longer length, 20–28 lb stringing advice and a 22 × 21 string pattern.

Construction and context

Yonex USA lists HM GRAPHITE, CFR, Tungsten, 2G-Namd™ FLEX FORCE and Ultra PE Fiber in the material field. These are manufacturer-published construction labels for the cited model, not independent measurements or proof of a particular playing outcome.

Who it may suit

This entry may help a shopper verify an ASTROX 88S GAME listing against Yonex’s published configuration, tier, material labels, flex, length and stringing fields. Those catalog fields do not determine individual comfort, handling, fit, or on-court results.

Specifications in context

4UG5; 4U (83 g avg.)
Yonex’s page identifies the reviewed option as 4UG5 and separately gives a 4U average-weight notation; it should not be read as an exact individual-racquet measurement.
Medium shaft flex
This is Yonex’s published flex label for the model, useful when checking catalog information but not a promise about feel or results.
20–28 lbs stringing advice
This is manufacturer guidance attached to the listed configuration, not a universal setup instruction for every string or player.

Tradeoffs and caveats

  • Yonex lists the reviewed USA configuration as 4UG5, so a retailer listing with another weight or grip notation should be checked carefully.
  • The 4U (83 g avg.) statement is an average-weight notation, not an exact finished weight for each individual racquet.
  • The listed unstrung configuration means strings, tension, installation and grip changes can affect a finished setup.
