The Yonex BG80 shifts the focus entirely toward explosive power and lightning-fast speed. It is widely considered one of the absolute best premier attacking strings ever made by Yonex, favored heavily by advanced and professional players worldwide. The Black color variant offers a sleek, stealthy aesthetic that pairs perfectly with modern, aggressive-looking racquets. Technical Specifications Gauge (Thickness): 0.68 mm. This thinner, more aerodynamic profile cuts through the air faster and bites into the shuttlecock more cleanly than a 0.70 mm string. Core Material: High-intensity NYLON Multifilament combined with high-modulus Vectran fibers. Outer Material: Special Braided Oval Shaped High Polymer Nylon. Feel: Hard. It offers zero "mushiness"—you feel the exact instant the shuttle hits the bed. Key Performance Attributes Vectran Powered Repulsion: The defining feature of BG80 is the integration of Vectran—a high-strength, high-modulus polymeric fiber wrapped around the nylon core. This ultra-stiff material creates an incredibly snappy bed. The moment the shuttle touches the racket, it is instantly repelled with massive velocity. Overpowering Heavy Smash: Yonex explicitly brands this string for an "Overpowering Heavy Smash." Because it is thinner and stiffer than the BG65 series, you get maximum energy transfer on full-power cuts, resulting in steeper, faster smashes. Rough, Textured Texture: The outer wrap uses an oval-shaped braided fiber. This gives the string a slightly textured surface, which bites into the shuttle's skirt. This texturing translates to phenomenal control and spin for tight net drops, slices, and cross-court deceptions. The Trade-Off (Durability): Moving down to a 0.68 mm gauge means sacrificing pure lifetime. While Vectran strengthens the string structurally, it will wear out and snap significantly faster than the robust 0.70 mm BG65Ti—especially if you mishit near the top frame.
