BikeMaster 525 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 525 BMXR X-Ring Chain:
BikeMaster is a brand that focuses on quality, performance, and value priced products for motorcycles and ATV's.
BikeMaster 525 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 525 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 525 VX3 X-Ring Chain:
The VX Series chain is a great chain upgrade from O.E.M. and is D.I.D's most popular and widely used chain on both on and off-road bikes.
D.I.D 525 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.
D.I.D 525 ZVMX 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 525 SRX2 QX-Ring Chain:
The Ultimate Sportbike Chain: The SRX2 Series chains are an excellent value for any street machine. The SRX2 chains feature lightening holes, reduced friction and Quadra X-Ring design which increases chain life from up to two times longer than standard O-Ring chain.
EK Chains 525 MVXZ2 Quadra-X Ring Chain:
EK's Supreme Quadra-X Ring Chains, The Ideal O.E. Replacement.
EK's MVXZ2 Quadra-X Ring chain is the ideal replacement chain for any 1000cc street bike. Features like lightening holes in the sideplates, large-diameter pins, and friction-reducing Quadra-X Rings help ensure high-performance and up to two times increased wear life compared to a standard O-ring chain.
EK Chains 525 ZVX3 NX-Ring Chain:
The Pinnacle of Chain Technology.
Renthal 525 R4 SRS 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.
RK 525 XSO RX-Ring Chain:
As part of their continuing quality improvement program, the RK Chain Factory has made a running production upgrade to their best selling 525XSO chain. The 525XSO 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 525 GXW XW-Ring Chain:
525GXW is RK's premium quality 525 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.

RK 525 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.
RK 525 ZXW XW-Ring Premium High Performance Chain:
RK's ZXW series is used for both racing and general use. ZXW and RK's Drag Racing Chain 530PRODR are each made for very different disciplines, but both share the same racing technology which provides the ultimate in high performance drive chains. ZXW features MotoGP and FIM Suzuka 8 Hour Endurance technology and has proven superiority by winning 35 first place finishes out of 39 races at the FIM Suzuki 8 Hour Endurance Race.

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.
