Notes on Manufacturer Chain Type:
- SRS-ring - Renthal proprietary X-ring design. The special SRS ring is pre-loaded during assembly creating a spring effect. As the chain wears, conventional O-rings and X-rings lose their seal integrity, whereas the SRS ring is designed to maintain itself during use, keeping a tighter seal against the side plates. This offers increased longevity as the specially formulated grease remains incased around the critical pin and bushing area longer while also keeping dirt, water and other contaminants out.
- Z-ring - Renthal proprietary and patented X-ring design.
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.
Note:
Image is for reference ONLY, actual product will vary based on fitment and selection.
Some Helpful Tools:
Try the Motion Pro Chain Breaker & Riveting Tool or BikeMaster's Heavy-Duty Chain Breaker & Rivet Tool to make removing your old chain and installing your new chain as easy and painless as possible.

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.

Renthal 520 R3-3 O-Ring Chain:
Renthal R3-3 chains are specially developed utilizing Renthal's SRS technology to increase the service life.
The special SRS is pre-loaded during assembly, creating a spring effect. As a chain wears, conventional O-rings and X-rings loosen their seal whereas the SRS has the inherent ability to regulate a constant sealing pressure against the side plates throughout the life of the chain.
This offers increased longevity, as the specially formulated grease remains encapsulated around the critical pin and bushing area longer whilst preventing ingress of dirt, water and other contaminants.
- SRS Technology: Nitrile Self Regulating Seals (SRS) retain a special vacuum-injected grease around the critical pin and bush area, which extends the life of the chain.
- Shot Peened: Shot-peened alloy steel side plates for high tensile strength and maximum impact load resistance.
- High Carbon Steel Pins: High carbon alloy steel bearing pins for excellent prolonged resistance to wear, for both road and off-road riding conditions.
- Special Finish: Special finish: gold colored side plates and copper colored rollers help prevent corrosion.
- Pre Stretched: To help with an easy setup, each R3 chain is pre-stretched meaning adjustments are not required.
- Spec: Available in 520 pitch only, average tensile strength: R3-3 520 - 7420 pounds.
- Perfect Match: Most perfectly matched chain for Renthal Chainwheels (sold separately) allowing maximum power at the rear wheel. This also extends the life of both the chain and chainwheels.
- Notes: The Rivet link has also been changed to a hollow end to facilitate easier installation. Like the R3.2, a split link is still included in the box for easy track side fitment.

Renthal 520 R4 ATV Z-Ring Chain:
Renthal's R4 ATV Chain is a premium strength Z-ring chain with excellent impact load resistance, designed specifically to withstand the stress found in ATV applications. The R4 chain features a heavier duty construction process and materials than the standard Renthal R3-2 O-ring chain which increases its service life and tensile strength. The patented "spring effect" Z-rings guarantee constant lubrication for longer life and pins manufactured from special alloy steel also contribute to better resistance from wear. Thicker side plates and a quad riveting manufacturing process round out the upgrades on this ATV-specific chain.
- Patented Z-ring seals dramatically increase the life of the chain.
- Larger diameter pins manufactured from specially enhanced steel improve the resistance to shock loads.
- A quad riveting process on each pin increases the tensile strength of the chain.
