Notes on Chain Type:
- Q4 Sealed Ring - Q4 seal ring and reinforced pin and roller provide superior wear resistance, higher impact resistance and fatigue strength. Q4 seal ring offers less friction, which leads to less power loss, almost half that of standard O-ring chain.
- X2-Ring - D.I.D proprietary X-ring design. New X2-ring design provides 40 percent greater wear resistance and better overall chain life.
- SX2-ring - Slim-sized SX2 ring strengthen the stiffness by reducing clearance between plates. SX2 ring has better wear-resistant performance than SX ring by 30%.
- Quadra-X ring - EK Chains proprietary X-ring style.
- ZX-ring - Adopted new ZX-ring and lasts 15% longer than ZVX series.
- 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.
- RX-Ring - RK proprietary X-ring design. RK RX-ring seals are made from an advanced Nitrile Butadiene composite for maximum performance and wear life. Viewed in cross-section, the RK "RX-Ring" has two lubrication pools and seal points versus the single seal point / pool design of a regular O-ring chain.
- XW-Ring - RK proprietary X-ring design. Uses an advanced design with XW-Ring construction for better sealing that provides extended wear and chain life up to 100% over conventional chains. XW-Ring chains are the best high-speed, extreme heat performance chains available today.
- UW-Ring - UW ring thickness is 50% thinner than O-ring with longer life time.
- DG-Ring - Sunstar proprietary X-ring design. DualGuard sealed ring street bike chain technology where the sealing ring has an 'X' shape - meaning there are two sealing points and two lubrication pools versus the one-sided, single-lip design of a standard O-ring. This sealed ring design type dramatically improves lubricity in high heat conditions while providing lower friction and longer chain life.
- TG-Ring - Sunstar proprietary X-ring design. TripleGuard sealed ring technology where there are three sealing lips and lubrication pools on each side of the ring to maintain top performance in high heat, extreme conditions; the TripleGuard ring type is the best for lubrication and protection.
- Duo Glide (X-Ring) - Vortex proprietary X-ring design. Duo Glide seal design reduces heat and friction resulting in a seven times longer wear life than a standard O-ring chain.
- Tri Glide (X-Ring) - Vortex proprietary X-ring design. Tri Glide seal provides three pockets of lubrication and two stabilizers ultimately reducing heat, friction, and increasing wear life by as much as 10 times over standard O-ring chains.
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.
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.
Note: Image is for reference ONLY, actual product may vary based on fitment and selection.

D.I.D 520 VX2 X-Ring Chain:
D.I.D's Pro-Street X-Ring VX Series Chains are high quality X-Ring chains with superior strength to withstand the horsepower of today's dual sports and trials bikes. The VX Series uses D.I.D's patented low friction X-Ring for maximum performance.
- Greater rigidity (7% higher than previous VM chain) creates smother handling, reduced power loss and quicker response.
- Highest value in all D.I.D series.
- D.I.D X-Ring has half the friction and 50 - 100% longer wear life compared to typical O-ring chains.
- Superior longer life than previous VM series.
- Solid rollers.
- Shot-peened parts.
- Pre-stretched.
- Extended riveted bushing "Anti-Kink" design.
- Replaces the Professional O-ring V Series and the Premium X-ring VM series chains.
- Average tensile strength of 8,210 pounds.
- Wear life index: 3500.
- Ideal for bikes and ATV's up to 750cc.
- Weight (per 100 links): 3.35 pounds.

Half the Power Loss - Compared with Normal O-ring chains, 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.
1.5 to 2 Times Longer Wear Resistance - Compared with Normal O-ring chains, 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.

DID 520 ZVMX Series X-Ring Chain:
D.I.D's engineers are continuously improving chain designs in order to handle the tremendous horsepower loads of today's high performance motorcycles. In developing the new DID ZVM-X series, D.I.D focused on "Rigidity." Traditionally, "Tensile Strength" has been the bench-mark to indicate overall strength, but tensile strength is only a laboratory static measurement of a chain's fracture point. Rigidity, on the other hand, is the ability of a chain to withstand the forces that occur in the real world that riders experience. Increased rigidity means better power transfer from the engine to the ground, greater resistance to stretching under load, and overall improved performance that meets the demands of the current high-power bikes and the people who ride them.
Half the Power Loss - Compared with Normal O-ring chains, 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.
1.5 to 2 Times Longer Wear Resistance - Compared with Normal O-ring chains, 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.

Sunstar 520 RTG1 Works Tripleguard Sealed Racing Chain:
For a top of the line, premium-level roadracing chain, Sunstar offers the RTG1 series - Sunstar's highest performing roadracing chain - for 520 and 530 street applications (RTG1 = Road Triple Guard). This Works level chain features the TripleGuard sealed ring technology where there are three sealing lips and lubrication pools on each side of the ring to maintain top performance in high heat, extreme conditions; the TripleGuard ring type is the best for lubrication and protection. Both the 520 and 530 are available in pre-cut lengths and come in the gold color option (gold outer and inner plates). While the 520 is great for any bike 1000cc or less which already uses a 520 pitch, the 530RTG1 is suitable for the high-performance, larger displacement machines like the Suzuki Hayabusa, Kawasaki ZX-14R Ninja and others in the same class that use 530 pitch. Both options use the rivet-type connecting link and are well suited to handle the demands of the toughest racing conditions encountered on the street.
