*The number of corresponding links is the number of links in the case of full STD vehicle. Please note that the corresponding links may differ when replacing the number of sprockets or customized. *Please refrain from using it on the public road because it is a product designed for competition. *Changing the chain size must be done by yourself, and please make sure to check in the pro shop with a pro mechanic regarding installation. *It requires a special tool for ZJ: rivet type.
It is a race model that thoroughly sought zero friction
•Feature 1: Aim for clean in section The ERS 2 is the lightest in the 520 size chain, STD race chain with an overwhelming share of trials and races. Because it is a non-seal chain, it was almost used as friction/zero, formerly GP250.
•Feature 2: 520 Lightest It achieves the precise operability by reducing the weight of the spring and the reduction of the gyro effect by the weight of the trial competition and the driving part which divides a slight posture change from the clean to the deduction.
•Feature 3: Adopted Pin with stage It improves the rigidity of the chain by holding the outer rivet part and the outer plate so as to hold it by sandwiching the pin barrel (part in contact with the bush) by one step
•Feature 4: The life is increased by adopting cold forged solid bush It is a high stiffness bushing with a smooth surface that is seamless and excellent roundness. With the optimization of the contact surface between the pin and the bush and the specially developed special grease, the wear of the pin, which is the cause of chain elongation, is suppressed, and the wear life is improved by 1.2 to 4 times over the conventional type.
