Tired of frequent chain adjustments? Pro X solves that problem once and for all with their top notch X-ring drive chain that is manufactured by the leading chain factory in Japan, using only the highest grade Japanese steel. 

An X-Ring chain features X-shaped seals that help keep in grease and seal out dirt and water. The result is a chain that creates 40% less friction and has 150% better durability over the standard non sealed MX chain.

This chain is a 520 pitch and 120 links long, and includes master link and clip. Available in standard or gold color. Standard non sealed chains are available as well. 

  • Chains are pre-stressed and pre-stretched to reduce initial chain stretch
  • Rollers and plates are shot peened and heat treated to offer an incredible tensile strength in combination with low friction and high wear resistance
  • Pins feature an exclusive pin treatment providing an extremely hard outside coating
  • Inner plates are designed in a specific shape allowing less material to be used which in combination with the unique lightening holes results in a 3% overall lighter chain without compromising tensile strength
  • Pins are also heavy press fitted and are quad staked riveted for an ultra-strong connection
  • Weight of 100 link chain: 54oz
  • Made in Japan

520 chains come standard on most full size MX and offroad bikes. 520 is the pitch of the chain, or the distance between the drive links. Please see the "Fitment" tab for a list of specific motorcycles that come standard with a 520 size chain.

You must trim this chain to length, it will be too long out of the box. This is a standard procedure on every chain. Use a chain breaker tool to shorten the chain, which can be done in a matter of minutes. 

Since an X-ring chain is wider than a standard chain, always check that there is proper clearance to the engine cases near the front sprocket and any other places of close contact. Failure to do so could result in damage to the chain and engine.
