Each component benefits from RK's unique HIT (Heat Induction Transfer) process, ensuring all parts are properly heat-treated for maximum durability and performance.

  • Chromoly steel construction
  • Seamless rollers and bushings
  • Chromized pins improve wear resistance up to 2x over other non-sealed chains
  • HIT (Heat Induction Transfer) process strengthens components
  • Includes clip-style master link

Specifications:

  • Tensile Strength: 4,980 lbs
  • Max CC Rating: 150cc (Off-road)
  • Max Horsepower: 40
  • Weight: 3.70 lbs

Note: MXZ4 chains are for Supercross and Motocross and are not recommended for street use.
