Now you can achieve the fastest swing speed possible. The evolutionary new frame minimizes wind resistance to produce an ultra fast swing. New ISOMETRIC head shape maximizes the sweet spot, producing ultimate swing speed and consistent power, even on off-center hits. YONEX cutting edge design delivers amazing ball speed on the court. EZONE Ai is Driven For Speed.



YONEX evolved our ISOMETRIC Technology with an improved grommet system, applying both deep and shallow grooves inside of the frame. This New ISOMETRIC technology provides the EZONE Ai with a maximum sweet spot.


YONEX knows that many players catch the ball at the top of the frame. The new EZONE Ai delivers ultimate swing speed and maximum power even on off-center hits. Players can now hit with greater impact both on dynamic angles as well as powerful attacking shots.


Integrating the new NANOMETRIC material, which improves the bonding strength between carbon fibers at the center and bottom of the frame, reduces the weight shift to the top of the frame. This Trans-Weight System results in a racquet head that reacts faster for quicker maneuverability and produces the fastest swing speed in YONEX history.


DUAL SHUT SYSTEM improves comfort and control with every stroke. Shockless Grommets at the bottom of the frame reduces impact vibration and Quake Shut Gel, which is embedded inside the grip, removes even the most subtle discomfort from the frame. A 50% reduction in vibration compared to conventional models.

[Quake Shut Gel, vibration test]

Two identical bottles both containing water were placed onto a vibrating surface.
The bottle on the left is directly on the surface of the machine and is affected by the vibration. The bottle on the right is on Quake Shut Gel and is not as affected by the vibration.
This demonstrates how Quake Shut Gel will reduce vibration in our racquets.
