Product Details

BikeMaster is known for making well-built drivetrain components, and this 520x120 BMOR O-ring chain is a solid example. Designed for motorcycles, this chain offers improved durability thanks to its O-ring seal, which helps keep grease in and contaminants out. It's built to handle a good amount of power, suitable for street bikes up to 750cc and off-road machines up to 650cc.

The engineers at BikeMaster used computer analysis to optimize the component designs, which results in higher tensile strength. This chain boasts an average tensile strength of 8,500 lbs, meaning it can withstand significant pulling force. They also applied a specially controlled heat treatment to make the material tougher, and the reinforced roller design adds even more impact resistance and extends the chain's lifespan. You'll get both a rivet master link and a clip master link included, giving you options for installation.

It's important to make sure this chain is correctly matched to your machine's size and power output. If you're unsure about the proper fitment or installation, it's always best to consult a professional to avoid potential damage or injury.
