The D.I.D ERT2 chain is the most trusted chain in Supercross and motocross racing because of its reputation of meeting the high quality demands that are required when pushing the limits. It was designed with the intention of making a chain that is optimized for the purpose of racing. D.I.D beefed up the ERT2 chain by increasing the pin size by 3 percent to give the chain an average tensile strength of 8,100 pounds. Increasing the strength of the ERT2 chain did not come with a sacrifice of weight, in fact DID was able to shed 5 percent from the previous ERT chain.
Exclusively designed for motorcycle racing.
High-performance, lightweight and low friction chain.
3 percent bigger pin diameter and 5 percent lighter than former ERT.
Provides the highest wear resistance, tensile strength and impact resistance.
Average tensile strength of 8,100 pounds.
Wear life index: 430.
Rated for up to a 450cc motocross bike.
Weight (per 100 links): 2.99 pounds.
Includes a clip-style master link.
Notes: ERT and ERT2 Connecting Links are not interchangeable. Non-sealed chains require more regular maintenance than sealed (O-ring, X-ring) versions and are mainly recommended for off-road use.
