Iconic Status

A collectible Yonex racquet of the 1990s from the maturity of isometric design.

History

Part of Yonex’s isometric lineage, which began with the R-7 and R-22 of the early 1980s.

Collectibility and Value

Used €180–€300; excellent/original grip & cover €350–€600; rare pristine €700+. Traded on eBay, Catawiki.

Technical Notes

Thin beam and slightly head-light balance, built to maximize sweet spot size while preserving feel.

Sources & research note: specifications and prices are period-typical estimates; individual examples vary. Earlier versions of this profile named Monica Seles and Martina Navratilova; Yonex documents Navratilova with the R-7, R-22 and RQ-180, and Seles with Yonex from 1990, but not with this model, so those names were removed.
