Average tensile strength of 6,800 lbs

Traditional round O-ring chain that's a convenient blend of performance and affordability. RK's 520SO Chains are suitable for low- to mid-range cc motorcycles that came from the factory with sealed chains.

Solid rollers, solid bushings and quad riveted pins For extended wear-resistance.

Used by professional SX and MX race teams the MXZ chain features high-quality pins, bushings and rollers for maximum durability.

O-ring chain offers high durability. Component designs, optimized with computer analysis, provide higher tensile strength. Specially controlled heat treatment means tougher material. Reinforced roller offers higher impact resistance and longer durability...

Developed for performance, providing low friction for the most power transfer. Designed and constructed with high-strength steel and solid rollers for durability and longer life. Note: This chain must be correctly matched to the machine size and power...
