RK 525XSO MOTORCYCLE CHAIN

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.
