BikeMaster 520x112 BMXR X-Ring Chain

BikeMaster is known for making reliable drivetrain components, and this 520x112 BMXR X-Ring Chain is a solid example. If you're looking for an OEM replacement chain that can handle more abuse and last longer than a standard O-ring chain, this is a good option. It's designed to give you significantly more wear resistance, up to twice as much as a regular O-ring chain, meaning fewer replacements down the road.

They've put some thought into the design here. Using computer analysis, they've refined each part for higher tensile strength and used special heat treatment to make the material tougher. The Q4 seal ring and reinforced pins and rollers are key to its superior wear and impact resistance. Plus, that Q4 seal ring helps reduce friction, which means less power loss from your engine to the rear wheel – almost half that of a standard O-ring chain.

This chain is rated for engines up to 1,000cc for street use or 750cc for off-road. It comes with both a rivet master link and a clip master link, so you have options for installation. With an average tensile strength of 9,000 lbs, it's built to hold up.
