Renthal R1 Works Chain – 420/134L


R1 – MX Works Chain

Renthal R1 Works Chain is a high-performance, lightweight, low-friction, non o-ring chain specifically engineered for racing at the highest levels. Often described as “the best motocross chain available”, the R1 Works Chain has high resistance to elongation and severe abrupt stresses encountered in MX & SX racing. This is achieved by manipulating raw material composition to increase tensile strength and yield strength

Each R1 Works Chain features chamfered inner links, extended bushings, shot-peened outer plates and manufacturing processes. This reduces weight in a durable and safe motocross chain that can be trusted to deliver maximum power output in any condition.

Installation Instructions

  • Accordion

    Shot Peened


    The Steel plates are shot peened to give them a high tensile strength and maximum impact load resistance.
  • Accordion

    Chamfered Link


    The Inner links are chamfered, this process helps reduce the chance of chain derailment in the toughest conditions. * *415 and 420-R1 chain do not have chamfered inner links
  • Accordion

    Chromised Pins


    Specifically for the off-road market, the bearing pins are chromised, giving them excellent resistance to wear in the gritty conditions endured in off-road racing.
  • Accordion



    Pre-formed bushings distribute the load, resulting in greater chain life. The bushings extended to reduce friction between inner and outer link plates, maximising power output.
  • Accordion

    Special Finish


    The gold side plates have a corrosion resistant plating that provides it with an attractive colour to match all motorcycles.
  • Accordion

    Perfect Match


    Pair with any Renthal Chainwheel and get the maximum power at the rear wheel with an extended life for both chain and chainwheels.
