Note for installing X-ring chains:
As X-ring chains are wider than standard roller chains, when fitting an X-ring chain to a motorcycle that was fitted with a non O-ring chain as original equipment, it is essential to check that there is proper clearance of the engine cases near the countershaft sprocket and any other places of close contact. Failure to do so could result in damage to the chain and motorcycle and could ultimately cause the chain to fail.

D.I.D 520 ATV X-Ring Chain:
The D.I.D X-ring is superior to other types of O-ring designs; it has half the power loss and 1.5 to 2 times the wear resistance of a normal O-ring chain. D.I.D's patented X-ring construction reduces friction by twisting between the side plates instead of being squashed. Normal O-rings and other makers' modified O-rings have squashed points that increase friction. The twisting action of the X-ring disperses the pressure and minimizes power loss. The X-ring's four contact points greatly increase its sealing performance. This keeps the dirt out and the lubrication in much better than any other O-ring. X-rings have the greatest wear resistance of any other type of O-ring or non-O-ring chain.
- Uses a special steel alloy designed specifically to provide the extra strength required for quad racing.
- Features the same low friction, long wearing X-ring technology as D.I.D's VX, ZVM-X, ZLV, and ERV chains.
- The ATV X-ring chain is engineered to create additional pockets to lock in grease to prolong the life of the chain.
- Solid rollers.
- Shot-peened parts.
- High cylindrical and roundness accuracy.
- Exacting tolerances provide low friction.
- Pre-stretched.
- Extended riveted bushing "Anti-Kink" design.
- Average tensile strength of 7,600 pounds.
- Wear life index: 3250.
- Rated up to a maximum displacement of 750cc.
- Weight (per 100 links): 3.65 pounds.
