520 ERT3 Racing Chain

• Product Details

  The best chain in motocross just got better, the D.I.D. ERT3 chain has been proven by the top teams in the world. With cutting edge technology and designed for the extreme conditions of racing, the D.I.D. ERT3 has 25% greater anti-shock performance and a 5% higher tensile strength over the previous generation chain without changing the weight of the chain. This means that the ERT3 is stronger without compromise while keeping the rotational mass to a minimum. Used and tested by professional motocross teams such as Factory KTM, Honda, Yamaha, Kawasaki and Suzuki, the D.I.D. ERT3 is the next level of chain performance. The gold coating also adds that level of factory look while giving the ERT3 excellent durability.

  The D.I.D. ERT3 has SDH pin treatment that creates an extremely hard chromium carbide layer on the pin's surface while the inner core is maintained soft to absorb extreme shock loads.

  The D.I.D. ERT3 uses solid bushing technology for high wear resistance. The cold-formed solid bushings have a smooth seamless surface with complete roundness, giving the chain exceptional wear life.
