Features:

• New upgrade to the DID 520VT2 Chain
• NEW 520 ERVT breaks down the concept of the original motocross chain (non-O-Ring)and adds the benefits of an x-ring
• 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
• The clear choice of Top AMA teams. AMA riders rely on the 520 ERVT to achieve their success!
