ISOMETRIC^TM technology continues to help the world’s greatest players achieve global success.

Developed over 30 years ago, the ISOMETRIC^TM design increases the sweet spot by 7%*. Compared to a conventional round frame, a square-shaped ISOMETRIC^TM racquet generates a larger sweet spot by optimizing the intersection of the main and cross strings.

ISOMETRIC^TM delivers greater control without sacrificing power. ISOMETRIC^TMis a Trademark of Yonex CO., LTD.

M40X

A next-generation highly strong, yet elastic carbon fiber developed by Toray Industries, Inc.

Sonic Flare System

Max Acceleration

The revolutionary new graphite material TORAYCAR M40X and SUPER HMG provide unrivalled power and stability for maximum shuttle acceleration.

 

Ultra PE Fiber

The shaft is constructed using ‘Ultra PEF’ – ultra poly ethylene fibre – which is light enough to float on water yet able to withstand immense forces. these characteristics allow for maximum shock absorption.

 

Super Slim Shaft

Reduced Air Resistance

The slimmest racquet ever produced by YONEX vastly reduces air resistance whilst providing maximum feel.

 

Energy Boost CAP PLUS

Uniquely shaped cap which maximizes shaft performance.The front allows the shaft to flex, while the sides arch-shaped curve stabilizes the racquet face by preventing the shaft from twisting.

 

New Built-in T-Joint

The lightweight T-Joint increases stability of the shuttle on the strings, maximizing power and control.
