2G-Namd Flex Force
2G-Namd Flex Force is a highly elastic graphite material that allows the frame to flex and snap back quickly during impact. It is designed to support ball pocketing and spin potential while retaining a responsive feel.
The Yonex VCORE 98 TOUR in Ruby Red is for players who handle fast exchanges comfortably and want the frame to remain composed against a heavy incoming ball. Its 98-square-inch head and 315 g nominal weight place it among the more demanding VCORE options. Extra mass can contribute to a firmer, more substantial contact, but it also asks for early preparation and a developed swing. This racquet prioritises purposeful attacking play over effortless handling.
A stable foundation for aggressive spin
The 16/19 string pattern leaves scope for varied trajectories, while the compact head suits players who strike cleanly and know how to direct the ball. Compared with the lighter 98L, TOUR takes more work to accelerate but has a more substantial character once the rally gets physical. It will appeal to a player who steps into shots and expects a consistent response when increasing pace.
The eighth-generation frame blends revised aerodynamics and ISOMETRIC geometry with materials such as 2G-Namd Flex Force, Servo Filter and VDM. Yonex brings string movement, frame stability and impact feel into the same design brief. VCORE 98 TOUR makes most sense when your technique can put that specification to work; it is not the easiest option simply because you enjoy topspin.
Technologies
Aero Trench
A recessed upper-grommet channel is shaped to reduce aerodynamic drag. Within VCORE it is designed to help accelerate the racquet head and support spin, without guaranteeing a specific result for every player.
ISOMETRIC
Yonex ISOMETRIC uses a more squared-off head geometry that optimizes main and cross string intersections. Yonex reports an approximately 7% larger sweet spot than a comparable conventional round head, supporting a more forgiving response when contact is off centre.
LINER TECH
LINER TECH uses straighter string-entry holes so the main strings can move more freely on impact. The design supports ball pocketing and a more forgiving stringbed response, including on off-centre hits.
Servo Filter
SERVO FILTER is an elastic film integrated between graphite layers in the frame. It is designed to reduce unwanted vibrations while preserving useful feedback to the hand for a more precise impact feel.
VDM
VDM (Vibration Dampening Mesh) is a flexible mesh wrapped around the graphite inside the grip. It filters unwanted impact vibrations to provide a smoother, more comfortable feel in the hand.
