RK 520 XSO Performance RX-Ring Drive Chain - 520XSO100
  • RK racing chains have been the overwhelming choice of World Championship Teams for the past two decades!
  • They have benefited from their long-term OEM relationships with the major Japanese motorcycle manufacturers; RK has supplied original chains and chains for racing
  • All high-quality RK chains are made in Japan except the standard RKM series, which are from Malaysia
  • All RK chains feature quad-staked pin riveting, solid rollers and solid bushings, except the RKM and standard series, which have two-point riveting and curled bushings
  • They are all pre-stressed and pre-stretched for better performance with fewer adjustments


  • Lubricated with specially-formulated, vacuum-injected U-grease locked in at 4 sealing points by tough rubber X-rings
  • 30 percent longer wear life than regular O-ring chains
  • Polished and shot-peened link plates
  • High tensile strength ensures reliable performance
  • Max. Engine Size: 750cc
  • Tensile Strength: 8,500lbs
  • Wear Life Index: 750
    (Wear life Index should be used as a comparison for probable wear life under identical circumstances. Think of it as a percent, with standard chains being 100)

    If your motorcycle came factory-equipped with an O-Ring, it must be replaced with an O-Ring chain
