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're all pre-stressed and pre-stretched for better performance with fewer adjustments


  • So good they outperform most of the competitions heavy-duty chains
  • Economical RKM series are made in Malaysia with Japanese materials and meet all RKs specifications
  • Max. Engine Size: 135cc Street/125cc Dirt;
  • Tensile Strength: 4,300 lbs;
  • Wear Life Index: 100 (Wear life Index should be used as a comparison for probable wear life under identical cicumstances. 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.
