Motorcycle DID chain step 520MX gold and black color with clip joint (RJ) for supermotard

Created for off-road racing, the DID chains of the ER series (520 ERT2, 520MX, 420NZ3, 428NZ) are extremely light and sliding chains that are not sealed (ie without O-Rings, X-Rings, etc.).

The secret behind the superior performance of the ER chains is the exclusive SDH (Super Dai Hard) pin treatment that makes the chain much stronger and more resistant to wear.
