DID chain 520

DID 520ERT3 Gold&Gold is a premium non-sealed racing chain from the ER (Exclusive Racing) series, designed specifically for the demanding conditions of motocross and supercross. It is used by factory teams such as Red Bull KTM, Monster Energy Kawasaki, Honda HRC and Star Racing Yamaha, mainly in the 250 cc and 450 cc classes. The new ERT3 generation brings 25% higher impact resistance and 3% higher tensile strength than its predecessor while keeping the weight low. The patented SDH pin treatment creates an extremely hard chromium-carbon surface with a tough core that absorbs shocks. Combined with cold-formed seamless bushings it ensures maximum wear resistance and low rolling resistance. The Japanese manufacturer D.I.D supplies its chains as original equipment (OEM) to leading brands such as Honda, Yamaha, Kawasaki, Suzuki, KTM and Ducati, which guarantees top manufacturing precision and reliability.
