The new 520DZ2 is a great value in a lightweight, high performance chain designed for Motocross Racing. This new chain has the same SDH pin treatment as D.I.D's ER Racing 520ERT2, 520MX, 428NZ and 420NZ3 chains giving the 520DZ2 a Two Time Longer Life than the previous 520DZ. The SDH pin treatment gives the chain's pins a hard chromium carbide outer layer while the pin's inner core remains soft. This gives
the chain the ability to withstand the severe impact from jumps but absorb shock. The new 520DZ2 is Made in Japan and designed for MX motorcycles up to 450 c.c.'s. The 520DZ2 is now available at a new low competitive price at motorcycle dealers and accessory stores in North America.
