Notes on Chain Type:
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.
BikeMaster 520 BMOR O-Ring Chain:
O-ring chain offers high durability. Component designs, optimized with computer analysis, provide higher tensile strength. Specially controlled heat treatment means tougher material. Reinforced roller offers higher impact resistance and longer durability.
BikeMaster 520 BMXR X-Ring Chain:
BikeMaster 520 BMXR X-Ring Chain - Colored:
BikeMaster is pleased to announce the addition of colored chains to their BMXR Series Sealed Chain product line. The chains will now be available in red, blue, green, yellow, orange and pink, making it easy for customers to customize their bikes to fit their style.
Made in Japan, each chain is an O.E.M. replacement Q4 Sealed Chain that offers 1.5 to 2x longer wear-resistance than standard O-ring chains. They have been designed with computer analysis to provide refined components and higher tensile strength. Each chain has also undergone a specially controlled heat treatment. This results in a chain that is tougher and more durable. The Q4 seal ring with reinforced pin and roller ensure higher impact resistance and fatigue strength as well as less friction.
BikeMaster 520 BMZR Z-Ring Chain:
Specifically developed for today's 1,000cc to 1,400cc, high-performance sport machines. High-quality components coupled with a factory-greased seal ring ensures superior rigidity. High-tensile steel used throughout the chain components; larger pins mean loads spread out over wider area, resulting in longer life and more strength. Specially controlled heat treatment means tougher material and more durability.
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.
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.
D.I.D 520 VR46 X-Ring Chain:
MotoGP rider Valentino Rossi has teamed up with D.I.D to create the signature series VR46 racing chain, with which his Petronas Yamaha Racing Team YZR-M1 will be equipped this season. The chain features VR46's "Sole e Luna (Sun and Moon)" symbol mark, and it runs a silver outer plate, and gold inner plate, with a VR46 yellow master-link. For racing and Rossi enthusiasts, this will be a golden opportunity to use a product backed by The Doctor himself.
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.

EK Chains 520 ZVX3 NX-Ring Chain:
The Pinnacle of Chain Technology.
Renthal 520 R3-3 SRS Road Chain:
Renthal R3-3 chains are specially developed utilizing Renthal's SRS technology for increased service life. 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.
Renthal's R4 SRS Road chain is a specially developed sealed ring chain utilizing Renthal's Self Regulating Seal (SRS) technology to increase the service life of the chain in road applications. 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.
The Renthal "Road R4" chain is supplied with a solid pin rivet link, matching the durability of the chain.
A highly specialized lightweight 520 sealed-ring chain developed exclusively for Superbike racing applications where a combination of lightweight and durability are a must. Utilizes Renthal's self-regulating seal (SRS) technology to increase service life. The specially developed self-regulating seal (SRS) ring is pre-loaded during assembly creating a spring effect. As the chain wears, conventional O-ring and X-rings loose their seal, however, the SRS ring has the ability to unload itself during use keeping a tighter seal against the side plates. This offers increased longevity as the specially formulated grease remains trapped around the critical pin and bushing area longer while also keeping dirt, water and other contaminants out.
As part of their continuing quality improvement program, the RK Chain Factory has made a running production upgrade to their best selling 520XSO chain. The 520XSO chain features RK's proprietary "RX-Ring" seal design and is offered in 520, 525 and 530. 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. RK's new GBXSO chains offer quality, performance and unbeatable value, for all but the most demanding high performance applications.
RK 520 XRE XW-Ring High Performance Chain:
RK's XRE series chains are the successor to XSO chains. Compared to XSO, XRE series chains feature a 20% longer wearlife. XRE chains include XW-sealing rings which provide two lubrication pools which help protect against high-speed abrasion and prevent dirt and debris from penetrating the inner rollers / bushings of the chain. XRE series chains are available in 520, 525 and 530 pitch. XRE's features create a perfect balance between high tensile strength and light weight while maximizing wearlife.
520GXW is RK's premium quality 520 XW-Ring chain. XW-Ring chains are the best high-speed, extreme heat performance chains available today. So, If you've modified your ride into an extreme high-speed machine, you need the strength and performance of GXW.

Developed in collaboration with MotoGP and World Superbike teams to produce the ultimate racing chain.
Sunstar 520 Road Dualguard Sealed Chain:
Sunstar's heavy duty, street motorcycle chain model is the RDG series (RDG = Road Dual Guard) for 520, 525 and 530 applications. It uses Sunstar's 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 - and it is available for just about every street motorcycle on today's market. It comes in the natural color option and uses a strong rivet-type connecting link. For a higher performance road chain at a non-premium price, the Sunstar RDG answers the bell and is great for everything from everyday commuting to closed course riding.
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.
