DID is the leading original equipment manufacturer with nearly 70% of all Japanese motorcycles and many European brands. Leading racing teams in road and off-road sports rely on the technology of DID. DID chains offer a good price-performance-ratio with high controlled quality, which is continually developed forward by research and innovation.

An exclusive hardening process of the bolts increases performance of the chains. Due to this special process the surface gets a hard layer but the bolt core stays soft. The bolts receive an enormous impact force, vibrations are easily absorbed.

This chain lock fits all 520 VT2 X-Ring D.I.D. chains.
