As part of their continuing quality improvement program, the RK Chain Factory has made a running production upgrade to their best selling 520XSO chain. The 520XSO 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.
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 8,500 pounds.
Wear life index: 750.
Maximum displacement (street / dirt): 750cc / 750cc.
