High Repulsion Power — Stiff Feel, Loud Sound, Raw Smash Transfer
The Yonex BG80 is built for players who want direct, explosive power transfer on every shot. Its High-Intensity Nylon core wrapped in rigid Vectran fibers creates a stiff, locked-down string bed that minimizes deformation on impact — sending the shuttle off the strings with a loud, authoritative sound and maximum force behind smashes and clears.
At 0.68mm, the BG80 sits in the mid-gauge range, balancing repulsion and durability for players who hit hard and hit often. Made in Japan.
Best for: heavy singles smashers, back-court doubles players, and players who want a solid, stiff string bed with direct raw power transfer.
HIGHLIGHTS BG80 at a glance
SPECS String specifications
TECHNOLOGIES How the BG80 works
RACKET MATCHING Physics-based string pairing
The BG80 is a power-amplification string. It works best when paired with rackets where raw smash force is the primary goal, or as a counter-balance string to soften overly fast or thin-feeling setups.
Astrox 99 Pro / 88D Pro / 88D Tour
Locks in the head-heavy smash power of these frames. The stiff BG80 bed transfers maximum force from the frame’s mass into the shuttle on full-swing smashes.
Nanoflare 800 Pro / 1000Z
Adds weight and solidity to head-light frames that can feel too fast or thin. The BG80’s stiff bed gives back-court substance to speed-oriented rackets.
Astrox 88S Pro
Pairs with the 88S Pro’s net-attack geometry to add raw power on cross-court drives and mid-court interceptions where a stiff string bed accelerates the shuttle.
Arcsaber 11 Tour
Softens the Arcsaber 11 Tour’s control-oriented setup with added repulsion — useful for players who want more pop on clears without switching to a more aggressive frame.
Nanoflare 700 Pro / 77 Pro
Adds back-court power to medium-flex frames that benefit from a stiffer string bed to compensate for their softer flex profile on full-swing shots.
Astrox 77 Tour
Balances the 77 Tour’s medium-flex feel with a stiffer string bed, giving players more direct power transfer on smashes without changing the frame’s comfortable swing weight.
PLAYER FIT Who is the BG80 for?
Best For: Heavy Smashers, Back-Court Doubles Players & Players Who Want a Solid, Stiff String Bed
The BG80 is the right choice for players who prioritize raw power over touch or spin. Its stiff, rigid feel rewards aggressive back-court players who rely on full-swing smashes, powerful clears, and hard drives. It’s particularly well suited to head-heavy Astrox users who want to maximize the frame’s smash potential, and to doubles back-court players who need consistent, loud power on every attack. Players who prefer a softer, more cushioned feel or who prioritize net play and deception will likely prefer a more flexible string like the EXBOLT 65 or SKYARC.

At 0.68mm, it balances power and durability for hard-hitting players. Available at Badminton Warehouse in White, Yellow, Black, Sky Blue, Royal Blue, and Violet. Made in Japan.
