◆ Demonstrates its true value under harsh conditions and uses SDH processing! *For motocross only ● Directly descended from AMA/All Japan, non-seal chain exclusively for motocross ERT2 is strong, as shown by the overwhelming installation rate at the AMA Supercross/All Japan Championship. This is the strongest motocross chain, with a high balance of lightness and impact resistance that no other company can match. *This product is designed for competition use only, so please refrain from using it on public roads. ●Special pin processing "SDH" This is a processing method that forms a very hard chromium carbide film on the surface of the pin and disperses the highly hard carbide inside. It suppresses pin wear that causes chain elongation, and exhibits high wear resistance even in harsh environments. ●Stepped pin adoption By making the pin body (the part that contacts the bushing) one step thicker, it holds the outer caulking part and the outer plate between them, increasing the rigidity of the chain. ●Cold forged solid bushing increases lifespan Highly rigid bushing with seamless smooth surface and excellent roundness. By optimizing the contact surface between pins and bushes and using a uniquely developed special grease, pin wear, which is the cause of chain elongation, is suppressed, and wear life is increased by 1.2 to 4 times compared to conventional types. ★D.I.D chain joint symbol explanation The joint strength is expressed as RJ>FJ>ZJ. For sealed chains and medium displacement vehicles and above, we recommend using a ZJ (caulking) joint.・RJ (clip type): Can be used with pliers or pliers.・FJ (light press-fit clip type).Use "Kashimaru-kun" when press-fitting the plate. After press-fitting, work can be done with pliers.・ZJ (caulking type): A type that uses "Kashimaru-kun" for plate press-fitting and pin caulking. Precautions for use *This product is designed for competition use only, so please refrain from using it on public roads.
