RK 525XSO motorcycle chains are manufactured from heat-treated, high-carbon alloy steel. These chains
feature seamless rollers, shouldered bushings, and use nitrile butadiene seals for maximum performance
and wear life. RK 525XSO chains incorporate RK’s RX-ring design. Their RX-ring design has two lubrication
pools and seal points, versus the single-lubrication/seal point design of standard O-ring chains.
These chains are pre-stressed and heat-treated for maximum wear life and performance.
RK 525XSO chains offer quality, performance, and an unbeatable value for all of your
high performance applications.
