Description
A reliable 520-class drive chain is foundational to consistent power delivery and predictable handling on the track or strip. The RK 520 ZXW delivers the durability and heat tolerance demanded by high-RPM racing applications, with precision-riveted construction that eliminates weak points under sustained acceleration. Whether you're running a sport bike, kart, or small-displacement race engine, this chain maintains tight tolerances and resists elongation when it matters most.
The black scale finish provides corrosion resistance without sacrificing the lightweight design critical to minimizing drivetrain parasitic loss. Engineered for extreme-heat environments, this chain won't fail prematurely or require constant re-tensioning mid-season.
