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 PERCEPT 97L in Midnight Navy answers a specific question: what if you like the precision of a compact 97-square-inch head but prefer less static weight than the 310 g PERCEPT 97? At a nominal 290 g, the 97L is more approachable to move and prepare for quick exchanges while preserving the narrow 21 mm beam and focused contact area. It can be a compelling choice for improving players who already value controlled ball striking.
Focused feel without the heavier frame
This is not simply a beginner-friendly version of the 97. The smaller head still rewards reliable timing, and its 325 mm balance gives it a different distribution of mass from the heavier model. A 16/19 string pattern leaves scope for topspin, touch and shaped shots, while the lower static weight can make fast reactions and purposeful volley preparation easier to manage.
ISOMETRIC head geometry, FlexCon System, 2G-Namd Flex Force and SERVO FILTER all contribute to Yonex’s control-and-feel concept. Midnight Navy refreshes the appearance without claiming a new technical generation. Choose PERCEPT 97L when a smaller, more communicative head matters to you but a 310 g racquet feels unnecessarily substantial for your playing style.
Technologies
FlexCon System
The shaped, elongated shaft is engineered for controlled flex through contact, extending the ball-pocketing sensation and supporting deliberate placement on well-executed strokes.
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.
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.
Stiff Racquet Face Design
Additional graphite layers reinforce the racquet face during impact. Yonex positions this as a way to stabilize ball trajectory and improve shot-to-shot consistency while allowing the shaft to retain its designed flex.
