DID ROLLER CHAIN 520MX (G&B)

DID Roller Chain 520MX (G&B) open with clip lock

The 520MX is the Motocross Monster of D.I.D. It boasts the highest rated tensile strength among non-sealed chains at 8,930 lbs. Perfect for the beating that chains take during tough, off-road races. Utilizing the SDH pin treatment, with an extremely hard chromium carbide surface layer and a softer inner core, the 520MX is able to absorb shock loads without stretching and landing you on the box!

Trusted by the 2019 AMA SX Champion, Cooper Webb, and the Red Bull KTM Factory team, as well as 6X AMA ATV Pro MX Champion, Chad Wienen, the 520MX wins championships!

NOTE
If the motorcycle was delivered from the factory with an endless chain, this should not be replaced with an open chain with clip lock, but for safety reasons only with an endless or open chain with rivet lock.
If the motorcycle was delivered with an O-ring chain, it must be replaced with a chain of equal or better quality.
