MX series chain developed for motocross with Team Johnson Suzuki Bieffe in Europe; features 11% higher tensile strength. 20% higher fatigue strength. 13% stronger anti-tight joint performance, 17% higher roller impact strength and 20% longer wear resistance. D.I.D ER chain is designed exclusively for racing. 520ERT and 520ERM are used by the top factory Supercross and Motocross Teams. 520MX chain has higher tensile strength for maximum performance and is ideal for muddy conditions. For offroad applications where an O-Ring chain is preferred, D.I.D`s 520VM X-Ring chain provides excellent low friction performance. X-Ring chain has 1.5 to 2 times greater wear resistance than standard O-Ring chain. D.I.D`s exclusive DAI-HARD (`di-hrd) pin treatment is the secret behind the superior performance of our 520ERT, 520ERM, 520ERV2 and all NZ Series chains. Dai-Hard hi-tech pin treatment forms an extremely hard chromium carbide layer on the pins surface while maintaining a soft inner core. Dai-Hard treated pins have extreme impact strength while maintaining outstanding shock absorption. Dai-Hard creates a chain with superior wear resistance, anti-oxidation properties and performs well against invasion of hard foreign materials. Distinctive gold-plated finish.
