The RK 520XSO RX Ring Chain continues RK’s tradition of quality, coming pre-stretched, shot peened, and heat-treated just like all chains from RK. The 520XSO distinguishes itself by having an 8,500 pound tensile strength that makes it perfect for street applications up to 750cc in displacement. RK has also fitted the 520XSO with their unique RX sealing ring that gives the links and rollers two pools of lubrication to draw from and two sealing points to keep the chain lube in and abrasive buildup out. All this makes for a high performance chain that stands up to incredible stress while still remaining a great value.

  • For street and off-road applications
  • RX-Ring seals
