Standard (M) chains feature heat-treated medium carbon alloy steel construction. All components are heat-treated and shot-peened for maximum strength. They feature two-point pin riveting and solid rollers. Designed for motorcycles up to 400cc that did not come with an O-ring or heavy-duty chain as standard equipment. Chains include a clip-style...

Ideal for OE replacement on mid-size motorcycles. This lightweight and durable chain provides quick and smooth acceleration. Designed with cutting-edge technology from on-road and off-road racing. Features RK's original double-X-shaped 'XW-Ring' seal for exceptionally long chain wear-life.

The only reliable choice for serious racers, available in DRZ2 and MS series.

The finest motocross chains for the world's fastest riders. 428 SHDR chains include a clip connecting link.

Premium-quality sealed O-ring, RX-ring, and X-ring chains. Built for high-horsepower applications and today's extreme performance street bikes. MAX Series chains offer unparalleled tensile strength and are available in extra-long lengths for motorcycles with extended swingarms. Specific series are rated for street bikes up to 1,400cc.

Precise forging process leads to a stiff chain for better acceleration and more efficient engine work. Lightening hole allows for a lighter chain without compromising strength while removing mud and dispersing heat more efficiently. Non-sealed to reduce as much friction as possible. Chromium carbide pin surface coating increases hardness and...

For motocross use only. Tensile strength of 8,900 lbs. Includes clip connecting link. Maximum engine size: 500cc.

Economical QX-ring chain. Uses the same QX-ring as the SRX2 series chain.

Super-economical roller chains made from a special steel alloy with solid rollers and pre-stretched, shot-peened parts. Available in Standard and SR Heavy-Duty series.

Value O-ring chain that doesn't compromise quality or durability. High-tech heat-treated steel alloy construction. 420 SRO/428 SROZ chains include semi-press fit clip connecting link. 520 SRO6 chains feature lightening holes and includes rivet connecting link.

For competition and OEM replacement. Excellent value for any street machine. Features lightening holes, reduced friction and Quadra X-Ring design, which increases wear life from 1.5 to 2 times longer than a standard O-ring chain. 520 SRX2 chains come with clip-type master link. 525 and 530 SRX2 chains come with rivet-type master link.

Premium X-Ring chains where all components are shot-peened and heat-treated. Features a patented 'TFC' connecting link and a special low-friction 'X' type O-ring to increase performance and provide better sealing to keep dirt out and lubrication in. Offers superior strength to combat breakage. Originally comes with a rivet connecting link.

Greatly increased sealing performance with four sections. Keeps dirt out and lubrication in. Lowest friction of all type of O-rings. Twisting action disperses the pressure and minimizes power loss. Maximum wear resistance.

Pins for ER chains are put through a special patented heat-treatment process that produces a 1.5 times harder than conventional carbon heat treating, providing the highest wear resistance, tensile strength and impact resistance available. ER chain is used by top motocross/supercross OEM works teams and has a distinctive gold-plated finish....

Greater rigidity brings smoother handling, reduced power loss, and quicker response. Available in gold (G&B) or natural (unplated steel). Average tensile strength 9,220 lbs. Pre-stretched at the factory. VX Series replaces the Professional O-ring V Series and the Premium X-ring VM Series. Features the highest value and longest life in all D.I.D....

EK's strongest chains developed specifically for extreme sportbikes. For competition and OEM replacement. New NX ring lasts 15% longer than previous ZVX series chains, minimizes clearance between plates, and features improved stiffness and weight.

D.I.D's professional high-performance non-O-ring chain treated with a patented SDH pin treatment. This forms an extremely hard chromium-carbide layer on the pin surface while maintaining a soft inner core for shock absorption. This results in greater rigidity, 5% to 25% longer life, up to 19% higher tensile strength, and increased anti-oxidation...

D.I.D's high-performance O-ring chain with solid bushings for the longest possible wear and reinforced rollers for the greatest impact resistance. Recommended for machines originally equipped with O-ring chains. Originally comes with a clip connecting link.

A line of low-cost, high-quality solid roller chains featuring quad-staked pin riveting, special alloy steel construction, and an extended riveted bushing anti-kink design. Chains are pre-stretched at the factory and are intended for motorcycles originally equipped with non-O-ring chains. Each chain originally comes with a clip connecting link.

Retains all the low-friction, high-performance characteristics of the ZVM-X, but with improved rigidity for greater wear resistance and better overall chain life. Features maximum rigidity and originally comes with a rivet connecting link.

High-quality O-Ring and X-Ring style motorcycle chains, available in various sizes and pre-cut lengths. All chains are shot-peened, pre-stretched, and made in Japan.
