Speaking of motorcycle chains, I believe that most knights immediately think of the three major brands such as DID, EK and RK. These three major brands are undoubtedly like Wei, Shu and Wu in the three countries.

Speaking of motorcycle chains, I believe that most knights immediately think of the three major brands such as DID, EK and RK. These three major brands are undoubtedly like Wei, Shu and Wu in the three countries.

But in 2021, SUNSTAR, which originally specializes in making gear plates, announced the launch of a chain product! Could he be the "Jin" that unifies the three countries? Therefore, this time, the editorial department will analyze SUNSTAR in detail, sort out what benefits and disadvantages it has, and predict whether SUNSTAR can break through the siege in chain products! What kind of manufacturer is

SUNSTAR?

Before entering the analysis chain product, let's review the history of the brand SUNSTAR:

1930s: Manufacture of rubber patches for repairing bicycle tires and inner tubes

1940s: Launch of tubular toothpaste

1950s: Start of production of bicycle crank

1960s: Launch of motorcycle toothpaste entering the market of chewing gum, detergent and scraping products At this time, SUNSTAR has become one of the leading toothpaste manufacturers in Japan

1970s: We started to produce brake discs for motorcycles, and at the same time it became famous because of signing a contract with Harley to provide brake discs

1980s: Launched the "G.U.M" toothpaste series

1990s: Launched the "Ora2" toothpaste series that can remove plaque

2000s: Acquisition of Italian brake disc manufacturer Braking S.p.A. (now Sunstar Engineering Europe GmbH – Italian branch)

2021: SUNSTAR has made its first production of motorcycle chain products

So that's it! SUNSTAR, which is famous for its gear wheels in the motorcycle field, is actually the same company as SUNSTAR, toothpaste brand! After

SUNSTAR launched motorcycle gear discs and brake discs in the 1960s and 1970s, it has now become a high-quality brand and product supported by a large number of knights. Not only that, just like the new generation of HAYABUSA original disc is made by SUNSTAR, the high quality of its products is favored by many motorcycle brands as original parts.

By the way, the brand name is composed of "SUN" and "STAR", which means this reminds everyone to "brush your teeth when the sun rises in the morning and when the stars rise in the evening."

directly hits the production site through the video

. Since it is not open to the public, it is impossible to see the production site in person, but you can see the production site of the brake discs and chains through the video. It can also be found from the film that SUNSTAR has considerable production facilities and is good at metal processing. Is the

SUNSTAR chain reliable?

Now let's bring the focus back to the chain, which is SUNSTAR's new product launched in 2021. Although it looks no different from the general chain at first glance, its characteristics are still slightly different from the products of the other three chain brands; so, what types of knights are recommended for SUNSTAR's chain?

Recommended conditions for choosing SUNSTAR chain:

According to the author's actual contact and use it, the SUNSTAR chain is quite suitable for travel enthusiasts because it is quite durable and the practice of improving durability is not the same as the chains of other companies. This will be explained in detail later.

The conditions for using SUNSTAR chain are not recommended:

On the other hand, the conditions for using SUNSTAR chain are that motorcycles are mainly racing in tracks or racing sports that are often high-speed, low-speed, and repeatedly operated, etc., because the SUNSTAR chain is designed for general street driving rather than track driving, so if you are a track competition enthusiast, it is recommended to choose DID products.

SUNSTAR chains are different from other brands of products

Since we have introduced what brand SUNSTAR is and we can roughly analyze what kind of knights we can recommend to, let’s take a look at the benefits of choosing SUNSTAR chains. The smaller the tolerance between

and the gear disc = the more durable it is

Do you know there is actually a tolerance between the gear disc and the chain? According to SUNSTAR, there are many reasons for the wear of the gear disc, but one of the factors that accelerate wear is "tooth pitch offset".

tooth pitch offset is a phenomenon. Due to the slight differences in the chain pitch , the chain snail is not closely linked to the tooth plate, but it is still stuck by the gear. This phenomenon is not only caused by the initial tolerance, but also caused by the wear of various parts such as the chain bushing and pins for a long time to use, resulting in chain deformation.

Because the specifications of chain and gear plates, such as 520, 525, 530... are common specifications of all chain and gear plate products. Therefore, as long as the same size is selected, each brand product can be used together. However, if there is a slight deviation in meshing or contact points due to slight tolerances, it will accelerate the impact of the wear chain or gear plate life.

So, what is the chain launched by SUNSTAR this time? Its purpose from the very beginning was to create a chain that would not be able to create such subtle tolerances! SUNSTAR successfully extends each other's service life to the maximum extent by optimizing the tolerances between the gear disc and the chain!

Especially for those knights who originally used SUNSTAR gear plates, it is very recommended to change the chain to SUNSTAR system.

has only one option = Don’t hesitate

What issues should be considered when purchasing a chain? For the author, I will first confirm the applicable length and size, then choose the grade that is for long-distance travel or urban transportation, then choose the quick-button or thud joint type connector, and some products can also choose colors, etc. To be honest, this is very annoying.

In this regard, the SUNSTAR chain has only one level! As long as you see it is the applicable specification for the motorcycle model, it will be the applicable length. All you have to do is choose one of the three colors! This is all the work you need to do to choose a SUNSTAR chain.

Of course, there is only one level that cannot cover various usage situations from track competition to street driving. If your car is used for track driving, please consider other brands of chain products!

launches chains of just the right length for each car model

chain length and number of links usually depend on motorcycle models. For example, Super Cub now has 98, 100 and 106 links, CB400SF has 108 links, Z900RS has 114 links, etc. The length required for each car model is slightly different, but most of the chains that can be bought in general stores are integer links such as 110, 110, 120, 130, etc., and need to be cut according to the actual number of use.

However, SUNSTAR's chain can choose the required link length, so it is very convenient to cut it yourself!

But what about the quality?

No matter how good the catalog specifications are, it is normal to have doubts about new products, especially the important part of the chain. Since it is composed of a large number of parts, each part requires precision parts. This is a part that strictly emphasizes safety, because if problems occur, it is easy to cause accidents or failures.

so we actually installed it on the car of our working colleagues and conducted a long review! The following classification leads to several conclusions:

I slightly overweighted when installing. Although SUNSTAR is slightly heavier than ordinary chains, both the withering of the SUNSTAR logo and the color of the chain are very beautiful. I also appreciate the above advantages after using them. Therefore, SUNSTAR chain products are quite recommended; by the way, it is made in Japan.Cheap

does not mean bad quality!

From the above description, we can find that SUNSTAR's chain has many advantages, and what is even more surprising is that SUNSTAR's chain products are priced cheaper than other brands! Although it doesn’t mean to the product just by looking at the cheapness or not, it is a chain product launched by Japanese brands that are closely related to the chain and have a long history! And it is made in Japan so it has a certain product level. .

purchase gear plate + chain three-piece set at one time is even more discounted!

If you are considering replacing the chain and gear plate at the same time, we will recommend that you choose a three-piece group containing front and rear gear plates + chains! This way, the purchase of a set will be more discounted than purchasing a single item!

Conclusion: It is highly recommended to travel enthusiasts

This time, the author introduced the characteristics and advantages and disadvantages of the SUNSTAR chain in detail. Since it is a street chain, if your usage method is racing or a track, I will directly recommend that you refer to other brands of chain products.
