RK EXCEL Gb420mxz4 Drive Chain Gold 420 X 134 for ATV and Off-Road Vehicles

The RK EXCEL Gb420mxz4 Drive Chain is engineered for demanding ATV and off-road applications, offering exceptional durability and performance. Designed to accommodate swingarm movement and handle increased torque stresses, this chain lasts approximately 1.7 times longer than traditional O-ring chains. Its robust construction features thermal crack resistant sideplates that protect against damage caused by rapid heating and cooling cycles, which can compromise chain integrity over time. Regular inspection after impacts or debris contact is recommended to maintain optimal performance and safety. The chain's high tensile strength of 7,700 lbs ensures reliable power transfer under strenuous conditions, making it suitable for engines up to 750cc. Weighing just 3.70 lbs, it provides a balance of strength and lightweight design for off-road enthusiasts. The chain includes a clip-type master link for easy installation, with a rivet-type option available separately. While not intended for street use, the Gb420mxz4 is ideal for rugged terrains where durability and longevity are critical. This chain features a maximum width of 22mm and is built to withstand the demanding environments typical of ATV and off-road riding environments, ensuring consistent performance and extended service life in the toughest conditions.
