Yonex Voltric Z-Force II badminton racket is part of the Yonex Voltric series. The Voltric Z-Force II in tests overpowers the Voltric Z-Force; providing high initial and end shuttle speeds on smashes it keeps the shuttle folded longer during flight.
Traditionally, extra weight at the top of the racket frame helps to increase hitting power but reduces racket handling speed. In contrast, a lighter top to the frame increases speed but causes a loss of hitting power. For the first time, the new TRI-VOLTAGE SYSTEM successfully combines the contrasting characteristics of exceptional power and great handling. Yonex has developed a racket which achieves a combination of heavy smashes and speedy racket handling.
Nanopreme – NANOPREME is an original technology developed by YONEX to provide an ideal racket material. Carbon Nanotube (with unique characteristics produced by Nanoscience) is combined with epoxy resin to tightly bind carbon fibres. Together, they form an incredibly strong material construction. NANOPREME delivers high repulsion and high strength to expand the performance capability of the racket.
Head Heavy Balance – Head-heavy balance is vital to place maximum power on a smash. The VOLTRIC Z-FORCE grips the shuttle on the string bed and transfers power more efficiently so that the shuttle retains power and weight deep into the opponent’s court.
Speed and Power – VOLTRIC Z-FORCE increases power even further through the larger frame cross-section and improved stiffness. Six metres from the initial impact, the shuttle was still travelling over 25km/h faster than a shot played with a conventional racket. A smash shot with this power and weight is hard for an opponent to counter.
Compact Frame – In combination with our most efficient head-heavy balance, the VOLTRIC Z-FORCE frame has been made smaller to deliver the faster swing speed demanded by advanced players. By reducing the drag caused by air resistance, the head-heavy feeling is reduced and racket handling speed is increased.
Strong shaft for explosive power – A thinner shaft for greater flexibility is traditionally less stable, but a stiffer shaft with high stability can become fragile. The VOLTRIC Z-FORCE shaft with NANOPREME combines flexibility and stability for ultimate performance. The thinnest shaft in YONEX history, it still delivers exceptional flexibility and amplifies the energy of the swing
To amplify the sweet spot the Z-Force II uses a new grommet system that uses grommet strips on the upper to extend the strings and guide them smoothly to the next string. This helps pre-load nearby strings for a more reactive string bed.
