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.

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.
The D.I.D Standard Non-O-Ring Chain is designed for low horsepower, smaller displacement mopeds, scooters and vintage motorcycles.
Pinning your bike out of every turn might tear apart the stock chain, but D.I.D and their 420NZ3 Gold chain will not let you, or your race for first, down.
D.I.D's exclusive SDH (Super DH) pin treatment is the secret behind the superior performance of the NZ Series chains. This high-tech pin treatment forms an extremely hard chromium carbide layer on the pin's surface while maintaining a soft inner core. SDH treated pins have extreme impact strength while maintaining outstanding shock absorption. This treatment creates a chain with anti-oxidation properties and superior wear resistance against invasion of hard foreign materials.
Designed, tested and produced with the highest level of Pro Taper quality. The gold series chains are purpose built for today's demanding 4-stroke bikes and ATV's. Pro Taper chains are manufactured with lightweight, ultra high-strength chromoly steel alloy for added performance and durability.
Renthal's R1 Works Chain is a high-strength non O-ring chain with excellent impact load resistance designed specifically to withstand the stress found in off-road applications. This chain is the choice where a combination of high strength, light weight and maximum power transfer are important considerations.
Sunstar 420 MXR1 Works MX Racing Chain:
Sunstar's MXR1 Works MX / SX / Off-Road race chain (MXR = Motocross Xtreme Racing) is a premium quality, highly durable non-sealed chain specifically designed for Motocross, Supercross and/or off-road racing. Featuring Sunstar's oversized TripleStar treated ultra hard pins and 100% heat treated components, the MXR1 chain is constructed to handle the demands of the highest levels of racing. This is also one of the lightest MX chains on the market thanks to its superlight design - the 520MXR1 120 link version weighs less than 3.6 pounds, yet is super strong with an 8,970-pound tensile strength rating. Its combination of strength, durability and light weight make it the top choice for serious racers.

D.I.D 520 Standard Chain:
D.I.D is the number one motorcycle chain in the world. D.I.D chains are used by factory races teams from all manufacturers in race series everywhere.
D.I.D 520 DZ2 Chain:
The All New D.I.D 520DZ2 is the best value in a lightweight, high-performance chain designed for motocross racing.
D.I.D's exclusive SDH (Super DH) pin treatment is the secret behind the superior performance of the DZ Series chains. This high-tech pin treatment forms an extremely hard chromium carbide layer on the pin's surface while maintaining a soft inner core. SDH treated pins have extreme impact strength while maintaining outstanding shock absorption. This treatment creates a chain with anti-oxidation properties and superior wear resistance against invasion of hard foreign materials.
D.I.D 520 ERT2 Chain:
The D.I.D ERT2 chain is the most trusted chain in Supercross and motocross racing because of its reputation of meeting the high quality demands that are required when pushing the limits. It was designed with the intention of making a chain that is optimized for the purpose of racing. D.I.D beefed up the ERT2 chain by increasing the pin size by 3% to give the chain an average tensile strength of 8,100 pounds. Increasing the strength of the ERT2 chain did not come with a sacrifice of weight, in fact DID was able to shed 5% from the previous ERT chain.
D.I.D 520 NZ Heavy Duty Chain:

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.
- 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.
- 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.
The best chain in motocross just got better, the D.I.D. ERT3 chain has been proven by the top teams in the world. With cutting edge technology and designed for the extreme conditions of racing, the D.I.D. ERT3 has 25% greater anti-shock performance and a 5% higher tensile strength over the previous generation chain without changing the weight of the chain. This means that the ERT3 is stronger without compromise while keeping the rotational mass to a minimum. Used and tested by professional motocross teams such as Factory KTM, Honda, Yamaha, Kawasaki and Suzuki, the D.I.D. ERT3 is the next level of chain performance. The gold coating also adds that level of factory look while giving the ERT3 excellent durability.
The D.I.D. ERT3 has SDH pin treatment that creates an extremely hard chromium carbide layer on the pin's surface while the inner core is maintained soft to absorb extreme shock loads.
The D.I.D. ERT3 uses solid bushing technology for high wear resistance. The cold-formed solid bushings have a smooth seamless surface with complete roundness, giving the chain exceptional wear life.
Sporting the same quality as all DID chains, the 520 ATV2 is a robust design with thicker plates for increased strength and heat dissipation. Perfect for hard-on-the-throttle quads. Don't worry about increased friction. With the "X" type sealing ring, friction is kept at bay with sealing surfaces that hold more lubrication in against the rollers and pins. With design like this, DID has made an ATV chain you'll adjust once and then keep on your bike for seasons to come.
D.I.D 520 ERV3 X-Ring Chain:
The D.I.D ERV3 X-ring chain is the ultimate high-performance, lightweight, low-friction race chain available and is used extensively by many off-road race teams. The ERV3 X-ring chain utilizes D.I.D's patented X-ring technology which reduces friction by 50% over standard O-ring chains for minimized power loss. The pins on the ERV3 X-ring chain have been put through a patented heat-treatment process to produce a pin that is 1.5 times harder than conventional pins. The result is a chain that is significantly stronger and offers better wear resistance than many other chains on the market. D.I.D ERV3 X-ring chains feature a gold-plated finish that resists rust and adds a little style to your motorcycle or ATV.

Renthal 520 R3 O-Ring Chain:
Renthal's R3-2 O-ring Chain is a high-strength sealed-ring chain with excellent impact load resistance designed specifically to withstand the stress found in off-road applications where an O-ring chain is desired. This chain is the choice where a combination of high strength, light weight and maximum power transfer are important considerations. The O-rings help extend chain life by retaining the special vacuum-injected grease near the critical pin area. Chain comes pre-stretched to shorten break-in period.
Renthal 520 R1 Race Chain:
Renthal's R1 Works Chain is a high-strength non O-ring chain with excellent impact load resistance designed specifically to withstand the stress found in off-road applications. This chain is the choice where a combination of high strength, light weight and maximum power transfer are important considerations.
