Reinforced pins and rollers enhance impact resistance and fatigue strength, making it suitable for demanding applications. With an average tensile strength of 9,300 lbs., this chain is compatible with street bikes up to 1,100cc and off-road bikes up to 900cc. It includes a rivet master link for secure installation. Proper matching to the motorcycle's size and power output is essential to ensure safety and optimal performance.
