Product Description

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 new upgrade GBXSO and non-gold XSO chains features RK's proprietary "RX-Ring" seal design and is offered in 520, 525 and 530 versions. 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.

  • High-performing, durable chain that will last five to eight times longer than your standard motorcycle chain.
  • Constructed from polished, shot-peened alloy steel providing high tensile strength for maximum performance.
  • RK RX-ring seals are made from an advanced Nitrile Butadiene composite for maximum performance and wear life.
  • Side plate treatment helps prevent corrosion.
  • Designed to make any motorcycle look stylish.
  • Average tensile strength of 8,850 pounds.
  • Wear life index: 750.
  • Maximum displacement (street / dirt): 900cc / 750cc.

How does the chain need lubed?
I was streching the swingarm 10 inches on a gsxr750. I was wondering if the chain will hold up on long runs of 85mph? I despize the lube slinging off and probaly wont lube it as much as i should, would anyone know if this part will be the best for the money????? any recommendations??

With an O-Ring chain you will want to keep it lubed other wise the o-rings in the chain will burn up and the chain is useless.. so proper maintenance as far as lubing goes is critical. And with a 10in extension on your swing arm I don't think a 120links will be long enough. So if you are looking for a chain you don't have to run lube in I have no recommendations for you.
