High-performance, lightweight low-friction chain designed to meet the performance needs of Moto3 racing. ERZ chain is upgraded with exclusive Super Dai Hard pins put through a special patented heat-treatment process that makes them 1.5 times harder than conventional carbon heat treating. Twice the wear-resistance of original D.I.D. 415 ER chains, and the 4,540 lbs. average tensile strength is a 15% increase
