The Yonex Nanoflare 800 Tour is designed for advanced players who value ultra-fast swing speed, exceptional handling and precise control. According to Yonex's official site, it features a stiff flex shaft.
It's available in two variants: 4U (G5, G6) and 3U (G4, G5, G6), with recommended stringing tensions up to 28 lbs (4U) and 29 lbs (3U).
Although the manufacturer does not explicitly list the balance classification, independent spec sheets mention the racquet has a predominately head-light balance feel, catering to fast reactions and front/mid-court play.
This model features Yonex's built-in T-Joint, HM Graphite and Super HMG shaft materials, and the frame is extended by 10 mm over standard length for added reach.
A stiff shaft offers maximum control and precision, ideal for players with fast swing speeds who can fully load the shaft.
A head-light design increases speed and maneuverability, perfect for fast defensive play and quick doubles rallies.
