The 420NZ was developed with the requirements of SX and MX racing in mind and is therefore specially reinforced. The wheels of the 420NZ are made of round material and therefore have no seams. Weak points, such as those in rolls made from wound sheet metal strips, are thus avoided. In addition, the 420NZ has rivets manufactured using a special process (SDH) that have a high surface hardness. DID is the leading original equipment manufacturer with almost 70% of all Japanese motorcycles as well as many European brands. Leading racing teams in road and off-road sports rely on DID technology. DID chains offer you a good price-performance ratio with high, controlled quality, which is constantly developed further through research and innovation.
