    ■About ADVANTAGE EXACT (EXACT) Full Forged Wheel
    -The pinnacle of riding supported by technology

    ADVANTAGE first approach was to focus on the requirements of the F-1 (Formula One), although Advantage had already studied motorcycle wheels in depth.

    The full forged wheel (full specification) is completed by the wisdom of all Japan.

    Advantage was particularly particular about using one of the best 8,000 ton presses in Japan.
    Of course, the product can be commercialized with 6000t press, but it is meaningless for EXACT unless it is 8000t press.

    Pressing aluminum and magnesium at 8,000 tons tightens their component densities and makes them more rigid, and also dramatically changes their microstructures, making them tougher and more supple.
    Microscopic magnification of the cross-section of a material reveals the state of its microstructure.
    Material not pressed at 8,000 tons has a point-like knotted structure.

    Such a state is hard, but it can cause cracking under a large impact, and it is inferior in terms of bearing capacity as indicated by elongation.
    A motorcycle has 4 wheels, not like a car. It is naturally susceptible to cracks or, in the worst case scenario, a fall.

    This is why Advantage insists on using an 8000 ton press.

    In the material pressed at 8000t, the microstructure changes from point-like to linear and is connected.
    This condition is also called the fiber flow effect (forge line).
    It is very important not to remove these as much as possible.
    The fir streamline will create flexibility and turn hardness into strength (physical strength).
    It flexes flexibly and absorbs shocks to prevent breakage.

    In order to enjoy many of these advantages, an 8000t press + cleavage spinning machine is required.

    In the past, forging was used to make Japanese swords, and in recent years it has been used to make important components for the aircraft industry. The goal is to create a lightweight, dense and strong wheel.

    The reason why ADVANTAGE EXACT advocates full forged wheels (full spec) is because it is the best way to ignore various costs.
    There are various forging methods to produce EXACT, depending on the model and material factors.

    Processing method (1) is forging (called hot punching).
    Conventional forged wheels are completed by painting after forging, but EXACT is not a finished product.
    Spinning is also a very important process.

    Advantage can say that sping is the technique that makes the most use of the effect of forging, and Advantage cannot find any other effective one.
    Forging is the process of stretching a beaten object.
    The reason why Advantage has chosen to use such forging technology is to ensure absolute safety.

    Some of them adopt a method called "split-open forging", which is named from the fact that the rim is formed by ripping open a disc-shaped material pressed at 8000t from the side.
    This technology is an excellent answer to the difficult problem of how to form a strong rim while reducing weight.

    In contrast to the process of spinning and stretching the rim, cleavage forging folds and stretches the open part.
    This folding and stretching process requires a much stronger force than spinning.
    Therefore, the component densities at the rim become even closer, and consequently, the stiffness is higher than that of spinning alone.
    This is one of the most notable advantages of cleavage forging.
    In addition, pay close attention to the heat.
    Heat is required to process the material, but if the material becomes too hot, it may become too soft and deformed after processing.
    Heat is also required for cleavage.

    Spinning is similar to the process of spinning a potter's wheel on a potter's wheel, but while the wheel is spinning, heat is also applied to slowly stretch and shape the material to fit the rim mold.
    Since the forging is done by pressing with a large roller, the rigidity is increased by the pressure, but a more remarkable phenomenon occurs in cleavage forging.
    When spinning, a clean line extends inside the microscopic world.
    This line is called a fiber flow (forge line), and since the microstructure of the material that has undergone the 8,000-ton press and cleavage is extremely linear and tight, this forge line becomes more beautiful and extended, resulting in a more rigid rim.

    Japanese swords have been forged since ancient times by swordsmiths who forged and kneaded the iron to create the Japanese sword.
    In the case of EXACT aluminum forged wheels, the quenching temperature is approximately 520 degrees.
    In fact, it is a very severe process, in which heat of 520°C is applied and then cooled.(Not applied to magnesium considering what it is.)

    The sword is forged by a master swordsmith, and the steel is heated to the point of turning crimson, and then immediately cooled with water for the so-called quenching process.
    This kind of heat treatment stabilizes the material and increases its rigidity.
    This is the kind of forging that many great swords have undergone while being forged by swordsmiths, and it is this forging that Advantage's EXACT is given.

    Since there is a possibility of thermal deformation due to rupture, it is cooled with water at once to prevent this.
    In addition, spinning is applied in order to make the form more precise.

    Processing Method (2) For forged aluminum wheels, in some cases, the wheels are forged using a 6,000-ton press and in other cases, they are forged using an 8,000-ton press.
    ADVANTAGE uses each of them to get the best characteristics.
    These wheels are finally subjected to rigorous testing outside of Advantage, and have been subjected to a series of severe tests by ENKEI TEST AND LABORATORY, which undertakes only tests for ENKEI CORPORATION, the highest-ranking wheel manufacturer in Japan, and these tests are reflected in our products.

    Just as a great sword was made by a master swordsman, the ADVANTAGE EXACT has been made with the utmost care and attention to detail to meet the ever-changing needs of the machines on the circuit.

    There is no such thing as an absolute.
    Constantly adapting to change is the hallmark of ADVANTAGE EXACT.

    As it is mentioned above, Advantage have repeatedly developed and provided feedback to refine their technology and to address the conditions of cars, which are completely different from those of motorcycles.
    A safer wheel that doesn't break is what Advantage wants most.
    The entire design process is carried out by Advantage.

    Special mention should be made of the parts that naturally make up those on motorcycles.
    The disc rotors, brake calipers and front forks are specially designed to maximize their features in a total package.
    The most important point of Advantage is that you can simulate and confirm the design.
    In addition, the tire mounting radius of the rim is made of a unique and ideal arc.

    Advantage also focuses on the air cushioning between the rim and tire.
    This shape is used to determine the expansion rate and volume of the air, and to create an ideal space.
    As the temperature rises, the thermal expansion of the air has a significant effect on the grip of the tyre and can also cause abnormal tyre wear.
    Advantage has designed the system to mitigate those fatalities.

    The recent trend of advantage over wheels is not lightness.
    If you want a light wheel, there is a 0kg wheel, if you install it, it will make your bike unstable and nervous.

    Have you ever heard of the earth piece? It is a gyroscopic piece that keeps spinning and spinning without falling down.
    Therefore, ADVANTAGE has already entered a different era from the era of competing for lightness.

    The manufacturer focuses on the balance of rotation and the flex and stiffness of the wheel.
    The flexure of the rim and the wheel itself has an important meaning to provide better information to the rider in the continuous running, turning and stopping.
    It is a wheel that is ripe for a smooth dialogue with the rider

    It is notable for its unique and stoic design.
    The design is shapely, with no extravagance.
    It is also used for racing machines and is absolutely safe for street use.

    Which is the best choice, forged aluminum or forged magnesium wheels?
    Advantage is often asked this question, but of course magnesium is more expensive.

    However, magnesium is lighter, but it also has better shock absorption and ride comfort.
    Aluminum has strength, but it is said that it will destroy the image of cast magnesium of a long time ago or accelerate weathering, which may arouse the anxiety of customers.
    The durability of the current ADVANTAGE EXACT full forged magnesium wheel is no longer comparable to the magnesium products of the past.


    Especially, the advantage is in the front and rear hubs and the rim.
    When the hub part is forged, a fist allowance is forged in the center of the hub part (like the same part of a drum) to increase the strength of the hub.

    As for the maintenance parts, we have been asked about the hub damper rubber.

    ADVANTAGE hub damper rubbers are made from proven SHOWA / KYB hub damper rubbers,almost 10 years after they were first sold, the hub damper rubbers themselves are still amazingly durable, and only 5 units have been sold in the ADVANTAGE shop.
    This is a proof that the material and design of the damper rubber is alive and well.

    The damper rubbers attached to the upper and lower end eyes of the rear suspension are thicker than 5mm to 10mm, and thinner than 3mm even for a liter class vehicle. In fact, how many of you have replaced the end eye rubber of your motorcycle rear shock?

    Recently, some racers say that fan-shaped damper rubbers are required to catch the power, but Advantage uses fan-shaped damper rubbers with an outer diameter of Φ36 because they cause more backlash.
    In the past, 6 damper rubbers were used for endurance races, but since they do not wear out significantly, the design has been shifted to 5.
    There is also this happy misadventure.

    The sprocket is XAM JAPAN's special product for EXACT.
    In Suzuka 8 hours endurance race, 525 and 520 size are supporting the machine's legs in JSB1000 class.

    Regarding wheel maintenance (especially magnesium).
    As for the characteristic of magnesium itself, it is easy to be oxidized without coating, and there was a time when it was said that it was hard to take care of when it appeared, but if it is ADVANTAGEEXACT produced by modern technology, you do not have to worry about it.
    If the paint is peeled or rubbed off and you can see the surface, you should touch up the paint immediately and keep it clean.
    When you wash your car, you can use neutral detergent.

    Before painting, chromate treatment with high corrosion prevention effect is applied as a base treatment.
    Chromate is also known as: Chromate treatment, chromate film treatment, chromate is a chemical film treatment for the purpose of corrosion resistance of aluminum alloy, magnesium, and the base of paint, is safe for a long time.

    By immersing the material metal in a solution containing hexavalent chromium and passivating it, a self-healing film can be obtained and chemical polishing can be performed at the same time.
    Currently, hexavalent chromium is regulated as an environmentally destructive substance and is replaced by trivalent chromium.
    Immediately after treatment, the surface of the metal is gelatinous, but when dried at about 60°C, it becomes a film with corrosion resistance and self-healing properties, and is ready for final coating.
