520 ZVM-X - Drive Chain - 120 Link - Black - Retains all the low-friction, high-performance characteristics of the standard X-ring while providing 40% greater wear resistance and better overall chain life - Designed for heavyweight motorcycles with tremendous torque and horsepower - ZVM-X Series is only available with a rivet connecting link, included with the chain - ZVM-X Series utilizes D.I.D's patented X-Ring seal and has greater strength than the VX Series and is designed for heavyweight motorcycles with tremendous torque and horsepower - Twisting action of the X-Ring increases its sealing performance and its four contact points minimizes power loss - ZVM-X Series’ Direct Energy Transfer, born from our experience in MotoGP, means greater stretch resistance under load - ZVM-X chain is a great chain for high powered street bikes but may also be utilized on adventure bikes

428 VX Series X-Ring Chain - 25 Feet - Greater rigidity brings smoother handling, reduced power loss, and quicker response - Pre-stretched at the factory - Superior longer life than previous VM Series

520 ERVT - Drive Chain - 120 Links - 520ERVT breaks down the concept of the original motocross chain (non o-ring) and adds the benefits of an x-ring - X-Ring helps keep your chain sealed with lubrication, limits dirt and mud from getting in-between the side plates, and only has 4 contact points with the plates which means less friction than the traditional O-Ring chain - More lightweight and longer chain life - By adjusting the materials, the 520ERVT is now 2% lighter and has a 15% longer lifespan, all while maintaining the tensile strength

520 ERV7 - Drive Chain - 120 Links - The 520 ERV7 chain boasts a 3% higher tensile strength due to stronger inner side plates and thicker pins - Due to increased X-Ring durability, the ERV7 sees a 13% wear resistance increase - 520ERV7 is the top-of-the-line racing chain for all types of motorcycle racing, on and off road - Incredible design and utilization of D.I.D's patented X-Ring seal technology makes the ERV7 a top performing racing chain available - Utilized by many factory teams worldwide
