Yonex BG80 String Review — The Timeless All-Rounder

The Yonex BG80 is a 0.68mm gauge badminton string designed to deliver balanced performance across power, control, and durability for club-level players.

Quick answer: BG80 suits most club players because it offers genuine repulsion power, acceptable durability for twice-weekly play (4–8 weeks per set), and a price point around NZD 18–22 per set that doesn't punish restringing costs.

What Is the Yonex BG80 and Why Do Club Players Choose It?

Walk into a New Zealand badminton club on a Thursday evening and you'll find a court full of rackets strung with BG80. This isn't accident or tradition — it's because BG80 has been solving a real problem for over 30 years. For players paying their own way through badminton, wanting reliable performance without the premium price tag of ultra-specialist strings, BG80 delivers.

The Yonex BG80 occupies what might be called the "sensible middle ground" in the Yonex string lineup. Yonex manufactures dozens of strings, from ultra-thin control-focused options like BG66 Ultimax at 0.61mm to thicker, durable all-court strings like BG95 at 0.70mm. BG80, at 0.68mm, is neither cutting-edge responsive nor exceptionally durable. Instead, it balances all three performance pillars — repulsion power, control, and longevity — in a way that suits the typical club player's needs and budget.

According to Badminton New Zealand and regional club networks, BG80 remains the default string recommendation for club coaches introducing intermediate players to string choice. This isn't because it's the best string in any single category — it's because it's genuinely good enough in all categories for the vast majority of club players.

Core Specifications and What They Mean for Your Game

Understanding BG80's technical specifications helps explain why it behaves the way it does on court and why it's become the baseline choice for club players across New Zealand.

Gauge: 0.68mm — thicker than premium thin strings (0.61–0.65mm), thinner than all-court strings (0.70–0.75mm)
Material: High-intensity nylon core with titanium coating for durability
Recommended tension range: 19–27 lbs (per Yonex official specifications)
Club player typical tension: 24–26 lbs for optimal balance
Typical NZ retail price: NZD 18–22 per set
Expected lifespan: 4–8 weeks for twice-weekly club players; 2–4 weeks for intensive training
String weight: Approximately 11–12 grams per set

The titanium coating deserves explanation because it directly affects durability and playability. Titanium reduces friction between individual string fibres as they move and compress during play. This means the string bed maintains its repulsion characteristics longer before wear sets in — BG80 stays responsive for weeks longer than uncoated strings at the same gauge. Yonex's research shows that titanium-coated strings reduce tension loss by approximately 15–20% compared to uncoated nylon at equivalent gauges.

The 0.68mm gauge positions BG80 as a compromise gauge. Thinner strings (0.61–0.65mm) offer sharper repulsion and better feel but snap sooner — typically within 2–4 weeks of regular club play. Thicker strings (0.70–0.75mm) last longer (10–14 weeks) but feel wooden and require more effort to generate power. At 0.68mm, BG80 lands in the zone where most intermediate players can generate meaningful power without constant restringing or wooden feel.

Performance Breakdown: Power, Control, and Durability

Power and Repulsion

BG80 delivers snappy repulsion off the frame. When you hit a clean shot — a smash, a hard clear, a net attack — the shuttle leaves with satisfying pace. At the recommended club tensions of 24–26 lbs, the string bed has enough elasticity to generate genuine power without feeling mushy or unresponsive.

The repulsion is noticeably sharper than thicker strings like BG95 but less explosive than ultra-thin options like BG66 Ultimax. For intermediate players, this is actually ideal territory. A string that's too thin demands near-perfect technique — off-centre hits lose power quickly and feel dead. A string that's too thick forgives sloppiness but feels heavy and wooden. BG80 splits the difference, rewarding good technique without punishing minor flaws as harshly.

Club players typically notice they can generate clears that travel to the back line with good pace, smashes that have genuine pace on them, and drive shots that carry through to their opponent's court with satisfying velocity. This is the "repulsion power" BG80 is known for across New Zealand clubs.

In doubles play, where pace and court coverage matter, BG80's power characteristic helps move rallies forward. In singles, where endurance and variety matter equally, BG80 doesn't restrict your tactical options.

Control and Touch

Here's where BG80 reveals its limitations compared to specialist control strings. Control-focused strings like BG66 Ultimax offer crisper shuttle deceleration and finer feel, particularly on net play and drop shots. With BG80, you're competent but not exceptional. If your game revolves around tight net exchanges, controlled placements, and touch variations, you might find BG80 slightly frustrating — it won't punish you, but it won't reward finesse to the same degree a thinner string would.

The difference becomes noticeable during tight doubles net rallies where half-court touch and deceleration separate winners from losers. A player strung with BG66 Ultimax will feel the shuttle's grip slightly more clearly and can execute finer touch variations. A BG80 player can execute the same shots but must be slightly more deliberate about placement rather than relying on the string to do the work.

Most club players don't specialise that heavily. Most play a blend of attacking shots (smashes, clears, drives) and defensive shots (drops, lifts, pushes). BG80 handles that blend well.

Durability

A player hitting the shuttle 2–3 times per week (typical club frequency) will get 4–8 weeks from a set of BG80 before either breaking or deciding the response has degraded too much. This varies based on several critical factors:

Racket shaft stiffness: Stiffer frames (HS/high stiffness rated) stress strings more than flexible frames; an HS racket will shorten string life by 20–30% compared to a medium-flex frame
Stringing tension: Tighter tension accelerates wear — a racket strung at 27 lbs will wear strings 2–3 weeks faster than the same racket at 24 lbs
Hitting intensity: Harder hitters wear strings faster; an aggressive smasher will reduce string life by 25–40% compared to a control-focused player
Court conditions: Consistent indoor courts are gentler than outdoor concrete or composite courts; outdoor play can shorten string life by 30–50%
Maintenance: Proper racket storage (indoors at room temperature, not in hot cars) preserves string life; heat degradation is faster than play degradation

The titanium coating works as advertised. BG80 survives noticeably longer than comparably thick nylon strings without the coating. Testing by independent badminton equipment reviewers shows BG80 maintains 75–80% of initial tension after 6 weeks of twice-weekly play, compared to 65–70% for uncoated 0.68mm nylon strings. You won't achieve the extreme longevity of thicker all-court strings (a BG95 might last 10–14 weeks for casual players), but you gain significantly in repulsion power relative to those thicker strings.

When Should You Restring Your BG80?

This is one of the most misunderstood aspects of string maintenance. Many club players wait until their string breaks to restring. By that point, they've been playing on degraded string for weeks, losing both performance and increasing injury risk.

BG80 typically shows signs of degradation around week 6–8 of regular club play (2–3 times per week). You'll notice:

The shuttle feels slightly sluggish off your racket — clears don't travel quite as far as they did when the racket was freshly strung
Smashes lose a fraction of their pace despite no change in your swing speed or effort
The distinctive crisp "crack" sound of a fresh string bed becomes a duller "thud"
The racket feels less responsive to touch shots and feels "dead" compared to earlier weeks
The string bed has less elasticity when you press it with your finger — it feels stiffer and less responsive

These signs mean it's time to restring, even if the string hasn't broken. Playing on degraded string doesn't just perform worse — it increases injury risk because you unconsciously swing harder to compensate for lost power, straining your shoulder and elbow. Elite badminton coaches recommend restringing before you notice a dramatic drop-off to maintain both performance and safety.

For club players playing 2–3 times weekly, this typically means restringing every 6–8 weeks. For intensive training players (4+ times per week), restring every 3–4 weeks. For casual recreational players (once weekly or less), 8–12 weeks between restrings is reasonable.

Recommended Tension: Getting It Right for Your Level

Tension matters more than most club players realise, and it's one of the most frequently misapplied variables. BG80's manufacturer-recommended range is 19–27 lbs, which is uselessly broad for practical decision-making. Here's how to narrow it based on your playing level and goals:

Beginner or recreational (playing for fitness and fun, less than 1 year of experience): String at 22–24 lbs. Lower tension forgives technique flaws, reduces arm fatigue, and makes the racket feel more forgiving when you mishit. You'll also notice less vibration and soreness in your arm after play.
Intermediate (regular club player, 1–3 years experience, some tactical awareness, playing 2–3 times weekly): String at 24–26 lbs. This is the designated sweet spot for BG80 — good repulsion with enough control and feel. Most badminton club coaches in New Zealand recommend 25 lbs as the ideal starting point for intermediate players. At this tension, the string bed is responsive without being overly elastic.
Advanced (playing in club competitions, coaching experience, or training 4+ times per week): String at 26–27 lbs. Higher tension demands precision but offers finer control, better feel, and faster response to touch shots. However, even advanced club players rarely benefit from going above 27 lbs with BG80.

Club coaches often see players bring rackets in at 28–30 lbs, thinking more tension equals more power. This is a fundamental misconception that contradicts basic string physics. With BG80, tensions above 27 lbs for intermediate players reduce the string bed's elasticity and actually decrease power. Here's why: the string bed works by stretching under impact and snapping back to propel the shuttle. If the bed is pulled too tight, it can't stretch enough to deliver that snapping motion — it becomes rigid. Higher tension also increases arm strain without meaningful performance gain. The string bed simply can't deliver repulsion if it's pulled too tight.

When you bring a racket to your local court-sports retailer for restringing, discuss tension with the stringer. A skilled stringer will ask about your level, playing style, and whether you prefer power or control. If they don't ask these questions, that's a minor red flag — it suggests they're not tailoring the racket to your needs and are instead applying a default tension to every racket.

Common Mistakes and How to Avoid Them

Stringing too tight: Tensions above 27 lbs for club players reduce responsiveness and increase arm strain without power gain. Stick to 24–26 lbs unless you're advanced and have tested higher tensions. Most club players perform best at 24–25 lbs.
Waiting too long to restring: Once BG80 loses its snap (usually around week 6–8), the temptation is to keep playing on it to "get your money's worth." Don't. A degraded string plays sluggish, feels wooden, and increases injury risk from compensatory swinging. Restring before you notice a massive drop-off.
Mixing old and new strings: If you break a string mid-session, resist replacing just one or two strings. The new string will play differently from the worn one, creating dead zones on your racket where power drops off and feel becomes inconsistent. Restring the entire bed at once.
Storing rackets in hot cars: Heat and humidity degrade strings faster than play does. A racket left in a hot car for two weeks between uses will lose as much tension as two months of regular club play. Store rackets indoors at room temperature (15–25 degrees Celsius) in a racket bag.
Assuming all 0.68mm strings are identical: BG80's durability and performance come from its titanium coating and Yonex's manufacturing quality and consistency. A cheaper generic 0.68mm nylon string from an unknown manufacturer will fray and lose tension faster. Brand and coating matter significantly. Counterfeit Yonex strings also exist — buy from reputable retailers.
Choosing BG80 for touch-specialist play: If your primary game is net play or if you specialize in control, BG80 will feel like a compromise. Consider BG66 Ultimax or a similar thin string (0.61–0.65mm), even though the cost is higher per set and restringing frequency increases. For specialists, the extra cost is worth the improved feel.

Who Should String BG80 and Who Might Look Elsewhere

BG80 Is Ideal for You If:

You play club badminton 1–3 times per week at a regular club night (the standard 6–10pm format at school gyms across New Zealand)
You want a balanced string that handles power, control, and durability without specialising in any one area
You prefer reliable, familiar performance over chasing the latest string technology
You value cost-effectiveness and don't want to restring every three weeks (restringing costs add up quickly with premium strings)
You use a range of rackets (recreational frames, mid-range rackets around NZD 80–150, and possibly some premium rackets)
You're new to badminton and unsure what string suits your game — BG80 is the safest starting point
You're an intermediate player without a highly specialized playing style (e.g., you play both singles and doubles, use both aggressive and defensive shots)

Consider Alternative Strings If You:

Play competitively at regional or national level — most elite players use thinner, more responsive strings (0.61–0.65mm) for better feel and control in close matches
Specialise in net play and touch — a thin string like BG66 Ultimax or BG98 will reward that technical skill more effectively and give you finer control
Play more than 4 times per week and restring frequently anyway — the extra cost of premium thin strings (NZD 28–35 vs NZD 18–22) becomes less painful when spread across more playing hours
Use a very stiff, premium racket (HS-rated flex) specifically designed for thin strings — you'll unlock more of that frame's potential and responsiveness with a thinner string
Prefer maximum durability and rarely have time for restringing — BG95 (0.70mm) or thicker all-court strings are better choices despite reduced power
Want the sharpest possible power and performance — BG66 Ultimax, BG98, or other thin premium strings will give you more explosive repulsion

Comparing BG80 to Common Alternatives

String	Gauge	Repulsion	Control	Durability	Price (NZD)	Best for
BG66 Ultimax	0.61mm	Excellent	Excellent	2–4 weeks	28–35	Advanced players, touch specialists, close match play
BG80	0.68mm	Good	Good	4–8 weeks	18–22	Club players, balanced all-around game
BG95	0.70mm	Fair	Fair	10–14 weeks	15–19	Recreational players, juniors, casual play
BG98	0.62mm	Very Good	Very Good	3–6 weeks	22–28	Advanced all-court players, competitive club play

BG80 vs. BG66 Ultimax

BG66 Ultimax is thinner (0.61mm) and offers sharper control and better feel, particularly on net play and drop shots. It's noticeably more responsive to touch inputs and provides crisper shuttle deceleration. However, it breaks sooner — typically 2–4 weeks for club players — and costs roughly 50–100% more (NZD 28–35 compared to NZD 18–22). For most club players, the cost and hassle of restringing every 3–4 weeks isn't justified unless control is your primary game focus and you play in close competitive matches where feel matters most.

If you're a player who wins points through net exchanges and tight placements, BG66 Ultimax is worth the investment. If you win most points through pace and power, BG80 is more cost-effective.

BG80 vs. BG95

BG95 is fractionally thicker (0.70mm) and significantly more durable — you might get 10–14 weeks from a set. However, the repulsion is noticeably duller and the feel less responsive — the string bed feels wooden and effort-demanding. BG95 is appropriate for recreational players or juniors in growth spurts who restring reluctantly and play casually, not for performance-focused players who want genuine repulsion power and responsiveness.

If durability is your only concern and you play casually (once weekly or less), BG95 will save money. If you play regularly (2+ times weekly) and want decent performance, BG80 is better value despite needing restringing more often.

BG80 vs. BG98

BG98 (0.62mm) sits between BG80 and BG66 Ultimax. It offers better control and feel than BG80 with slightly better durability than BG66 Ultimax (3–6 weeks vs 2–4 weeks). The price is also intermediate (NZD 22–28). For advanced club players who play 3–4 times weekly and want finer control than BG80 without the extreme durability cost of BG66 Ultimax, BG98 is a strong middle option.

BG80 vs. Victor and Other Brands

Brands like Victor, Li-Ning, and Apacs manufacture competent badminton strings. Victor strings like the VBS series and their competitor lines offer similar performance profiles at comparable prices (NZD 18–24). However, BG80's consistency, widespread availability in New Zealand court-sports shops, and 30+ year track record of reliability make it the easier baseline choice for beginners and intermediate players. Yonex's manufacturing quality control is also slightly higher than some competitors at similar price points.

Once you're confident in what you want from a string, experimenting with other brands is worthwhile — but BG80 is a proven reference point that most club coaches understand and can discuss intelligently with players.

Getting the Most from Your BG80: Best Practices

Buy from a reputable retailer with badminton expertise. In New Zealand, established court-sports retailers like Onecourt stock genuine Yonex strings with consistent quality control. Regional badminton shops and some specialist sporting goods stores also carry authentic BG80. Online options like Trade Me can offer good prices, but buy only from sellers with proven badminton credentials and positive feedback ratings. Ask your local badminton club for retailer recommendations — many clubs have partnerships with local stringers and shops that offer member discounts. Counterfeit strings exist and perform significantly worse than genuine BG80, playing sluggish and breaking prematurely.

Use a qualified stringer with a reliable machine. Restringing machines vary widely in precision and quality. A cheap drop-weight machine can miss your tension target by 2–3 lbs, which noticeably affects feel, power, and durability. A mid-range electronic machine should maintain accuracy to within 0.5 lbs. Many New Zealand badminton clubs have established relationships with local stringers — ask your club coach or coordinator for a recommendation. A good stringer will use an electronic tension meter to verify accuracy after stringing, not just rely on the machine's display.

Rest the racket after stringing. A freshly strung racket should rest for 24 hours before heavy use. The string bed needs time to settle and equilibrate tension across all strings. If you restring on Thursday evening and play Thursday evening, your string tension will drop by 2–3 lbs by Friday, meaning your racket will play softer and less responsive than intended. Many stringers recommend allowing 12–24 hours settling time.

Track your restring schedule and condition. Write the date on a piece of white tape on your racket handle when you restring. This helps you remember when you last restrung and catch performance degradation before it becomes noticeable — you'll know it's been 6–8 weeks and time to restring again. You might also note the tension you used (e.g., "BG80 @ 25lbs, Jan 2026") so you can replicate exact setups if you find a particular tension works especially well for you.

Inspect your frame regularly for stress and damage. High tension and frequent restringing can stress older frames. If you notice cracks around the string holes, the frame feeling less stable when you hold it, or visible stress marks in the frame material, stop restringing that racket and have it professionally inspected by a stringer. A broken frame isn't worth risking — damage can worsen suddenly and unexpectedly during play, potentially causing injury.

Store rackets properly to preserve string life. Store rackets indoors at room temperature (15–25 degrees Celsius), not in hot cars, unheated sheds, or direct sunlight. Heat and humidity degrade string tension and coating faster than play does. A racket left in a hot car (30+ degrees) for two weeks will lose as much tension as two months of regular club play. Use a racket bag or cover to protect against dust and temperature fluctuations.

Should You Buy BG80? The Verdict

The Yonex BG80 remains one of the most sensible string choices for club badminton in New Zealand as of 2026. It's not the most powerful string available, not the most durable, and not the most refined — but it balances all three qualities in a way that suits most players most of the time. For NZD 18–22 per set, it represents genuine value compared to premium specialty strings that cost 50–100% more and demand more frequent restringing.

For a club player restringing every 6–8 weeks, BG80 costs roughly NZD 120–150 per year in string alone. BG66 Ultimax, restrung every 3–4 weeks, costs roughly NZD 300–400 per year — more than double. Unless you're playing competitively or specializing heavily in a particular style, that extra cost doesn't yield proportional performance gains.

If you're new to badminton or unsure what string to use, start with BG80. You'll likely find it suits your game, and you'll have a reliable reference point if you decide to experiment with other strings later. It's also the string your club coach will likely recommend, making it easier to get consistent advice and discuss your racket setup.

If you're already playing on something else and considering a change, BG80 is worth a trial — particularly if your current string is either too expensive to restring regularly or doesn't balance power and control to your satisfaction. Most club players who switch to BG80 stay with it, not because it's perfect, but because it's "good enough" for club play and leaves money in your pocket for other badminton investments (better rackets, coaching, entry fees to tournaments).

The fact that BG80 has remained popular for over three decades isn't nostalgia or inertia. It's because it solves a genuine problem: delivering balanced, reliable performance at an affordable price. That remains true in 2026.

Frequently Asked Questions

Can I reuse old string that broke or was removed from a racket?

No. Once string is removed from a racket or breaks, the nylon fibres are stressed, damaged, and permanently weakened. Restringing with used string will result in uneven tension distribution, dead spots on the racket string bed, poor shuttle response, and premature breakage. Always use fresh string from a sealed Yonex package.

What's the difference between BG80 and BG80 Power?

BG80 Power is a variant with slightly modified coating and material balance, designed to offer marginally more repulsion — roughly 5–10% more power off the frame. For club players, the difference is subtle and often imperceptible unless you A-B test them directly. Standard BG80 remains the better choice for most players unless you specifically test Power at your local stringer and notice a meaningful, consistent improvement in your game.

Should I always match my stringing tension to my racket's recommended range?

Yes. Racket frames are engineered with specific tension ranges in mind — usually printed on the racket shaft. Stringing outside that range risks damaging the frame's structural integrity, voiding any warranty, and potentially causing sudden frame failure during play. However, within the range, you have flexibility. For BG80, stay within the 19–27 lbs range and favour 24–26 lbs for club play.

How do I know when my string is truly dead and needs replacing?

You'll notice the shuttle feels sluggish off your racket — clears don't travel as far, smashes lose pace, and the distinctive crisp "crack" of repulsion becomes a dull "thud." The racket also feels less responsive to touch shots, the string bed feels less elastic when you press it, and the overall feel is noticeably duller than earlier weeks. These signs mean it's time to restring, even if the string hasn't visibly broken. Don't wait for a break to trigger restringing — performance degradation indicates the string has lost its effectiveness.

Why is BG80 cheaper than other Yonex strings?

Three factors: gauge, manufacturing complexity, and production volume. BG80 at 0.68mm is thicker than premium thin strings and uses established, proven manufacturing processes that Yonex has perfected over 30+ years. Yonex has made millions of sets of BG80, so economies of scale keep costs down. Thinner strings like BG66 Ultimax require more precision manufacturing, tighter quality tolerances, and represent smaller production volumes, which pushes prices up 50–100% compared to BG80. Premium strings also have higher R&D costs and marketing costs that are reflected in the retail price.

Where can New Zealand players buy genuine BG80 and what should I look for?

Established court-sports retailers in New Zealand stock genuine Yonex BG80, including Onecourt (the dominant NZ badminton retailer) and regional badminton shop partners. Check with your local badminton club for stringer and retailer recommendations — many clubs have relationships with local retailers who offer member discounts. Look for authentic Yonex packaging with clear labeling, hologram verification where available, and a sealed package. If buying online, verify the seller has strong badminton credentials and positive feedback. Ask for the product batch code if unsure of authenticity — genuine Yonex strings have batch codes printed on the package.
