What are Yonex Pre-strung Badminton Racquets Pre-Strung with?

Product Knock Out

Contrary to popular belief, Yonex pre-strung badminton racquets are NOT pre-strung with Yonex BG65.

Virtually all of Yonex’ pre-strung badminton racquets are pre-strung with something called Yonex Demo Gut — a low-cost, extruded nylon monofilament that is nothing at all like Yonex BG65 multifilament.

Yonex Demo Gut is not intended for long-term adult use. It is a temporary string put in racquets to help them keep their shape and to help large sporting good stores sell racquets.

Yonex Demo Gut is not intended to function as badminton string in any serious way.

You will not find serious players at the professional or recreational level stringing their racquets with Yonex Demo Gut.

In fact, Yonex does not even sell Yonex Demo Gut.

The name tells you all you need to know. Demo Gut was created as a demo string. Essentially, it is a prop. It is a substitute for the real thing.

So when you buy a pre-strung Yonex racquet, you should plan to replace the strings in very short order.

What you replace it with is up to you. It will depend on the racquet you are stringing, the shuttles you are using, and what you need the string to do.

Yonex has an large selection of excellent badminton strings to choose from. Regardless of who you are or how you play, we will be able to help you choose a suitable replacement when you are ready.

How to Customize the Astrox 88

About the Yonex Astrox 88

The Astrox 88 comes in two versions. The Astrox 88D and the Astrox 88S. The models are identical with one exception, the 88S is about a centimeter shorter than the 88D. This is because the 88S is designed for players who play mostly from mid-court to front court while the 88D is for players who play mid- to back-court. Given the marketing for this racquet, stringers should expect that the Astrox 88D will be used by smashers and drivers while the 88S will be used primarily for drops, lifts and clears.

How to String the Astrox 88D

If you are stringing for advanced to elite level men using feather shuttles, we recommend using one of these strings.

If you are stringing for rec level men using nylon shuttles, then we recommend selecting something from this group.

Nylon shuttles, of course, are much harder on strings than feather shuttles. So some men may break strings more often than they like using string from the group above. In that case, it may be advisable to switch to something more durable.

How to String the Astrox 88S

As this is a shorter racquet intended for front court usage, it is most likely to be used by shorter and lighter players (ladies, for example) than the 88D. Our advice, therefore, it to string it with thinner, less durable strings.

Our string suggestions for players using feather shuttles includes this group of string options…

Our string suggestions for players using nylon shuttles includes this group of string options ..

As always, these suggestions are just starting points. Players who are having particular issues are advised to come into the store and discuss options with our experts.

Which Yonex Nanoflare is Best for Me?

Yonex Nanoflare Jr Badminton Racquet Head Blue Green

The Yonex Nanoflare series consists of head-light racquets that also provide extra shuttle speed and distance.

While many players around the world prefer the touch and maneuverability of a head-light racquet, the one downside to these racquets has been sacrificing the shuttle speed and power of a head-heavy racquet.

In 2019, Yonex upended that contradiction with the new Nanoflare 700, a head-light racquet built with unique technology and construction that helps adult players not only play nimbly but also achieve increased shuttle acceleration allowing them to hit deep into their opponent’s court.

To achieve this, designers and engineers at Yonex re-imagined frame design.

Firstly, the Nanoflare 700 was the first racquet to utilize the Sonic Flare System design, utilizing the latest in graphite technologies, such as TORAYCA® M40X*, to create a stable yet highly repulsive head shape.

Additionally, by designing a highly aero-dimensional shape built to compress and “snap back” they were able to realize an ultra-light racquet for players who demand agility, that was also able to launch the shuttle at speeds not before possible in a head-light racquet. This also resulted in a greater hitting feeling and less impact on the player’s arm.

Launching alongside the 700 were four other models in the head-light NANOFLARE series.

The 370 SPEED is designed for advanced players who desire improved smash speeds.

The 270 SPEED is intended for intermediate to advanced players seeking greater clears,

The 170 LIGHT is for beginning players who require the ultimate in lightness and maneuverability.

Meanwhile, the NANOFLARE JR combines the lightweight, maneuverability with added speed, distance and comfort of the 700 in a junior-sized racquet intended for competitive junior athletes.

Best Badminton String for Children

Yonex Aerobite Badminton String

The tendency for most parents is to string their child’s badminton racquet with the cheapest, most durable string possible.

Bad idea!!

If the parent’s goal is to increase their child’s enjoyment of badminton, then the string should help them succeed.

Very few children are frequent string breakers. Once they become teenagers that may change for some — especially for some boys — but very few children ever break badminton strings. So there is no need to go for maximum durability.

Instead, children’s racquets should be strung for maximum enjoyment.

Stringing children’s badminton racquets for maximum enjoyment means stringing their racquets with the thinnest, most powerful string you can get your hands on.

All of the strings in the table below have been chosen by our coaches as suitable for children up to 10 years old. It does not matter if they are boys or girls or what kinds of shuttles they are using. Children at this age rarely smash, so these strings will work with both nylon and feather shuttlecocks.


Best Badminton String for Children

The badminton strings in this table are recommended by our coaches are the best options for most children. The reasons why they are recommended are discussed in this post.

The reason for stringing children’s racquets this way is simple. Thinner strings increase power. Increasing power allows them to hit the shuttle further. Hitting the shuttle further means longer rallies. Longer rallies equal more fun.

On the other hand …

When parents string children’s badminton racquets with durable string they end up generating less power. Less power means fewer shots make it over the net which leads to shorter rallies and less fun.

In fact, if this happens in a game situation, the result equals less success and more failure, which for many kids is no fun at all.

Stringing kids racquets with thinner more powerful strings means — in a game situation — that they will be able to hit the shuttle deeper.

If Child A strings for power and Child B strings for durability, then Child A has an advantage. Assuming they are equal, Child A will probably have more fun than Child B.

If Child A starts playing well enough that he or she is hitting the shuttle out the back of the court or if Child A starts to break strings more often than his or her parents can afford, then it’s time to choose something more durable.

But switching to a thicker string before that happens is not necessary and may be counterproductive to the whole point of enrolling a child in an athletic program.

In other words, if you want your child to have fun playing badminton, string their racquets with string that will offer them the most amount of fun.
