525 O-Ring Rivet Chains

D.I.D VO Premium O-Ring (up to 900cc)
The VO Series is our professional O-Ring series chain that is a great OEM replacement on street and off-road bikes up to 900cc. With quad-stake riveted pins and solid bushings, you get great performance, strength, and chain life.

D.I.D VX3 Pro-Street X-Ring (up to 1000cc)
The VX Series chain is a great chain upgrade from OEM and is our most popular and widely used chain on both on and off-road bikes. The 525VX3 boasts a 41% longer chain life than the VO Series due to our patented X-Ring seal technology. It also has increased rigidity as to reduce flex, which gives you a more responsive and smooth driving experience.

D.I.D ZVM-X2 Super Street X-Ring (up to 1300cc)
The D.I.D ZVM-X Series utilizes our patented X-Ring seal and has greater strength than the VX Series and is designed for heavyweight motorcycles with tremendous torque and horsepower. The twisting action of the X-Ring increases its sealing performance and its four contact points minimizes power loss. The ZVM-X Series’ Direct Energy Transfer, born from our experience in MotoGP, means greater stretch resistance under load. The ZVM-X chain is a great chain for high powered street bikes but may also be utilized on adventure bikes.
