520EXR X-Ring chain Product Introduction
The 520EXR X-Ring Chain is strong and made to last a long time. It has a special X-Ring that helps stop the chain from stretching and makes it last longer. This X-Ring also makes the chain slide better, with less rubbing than a normal O-Ring chain. It is very light and super strong, with a pull strength of 4200.
The outside of the chain is really hard to stop it from wearing out, but the inside stays soft so it doesn’t break easily. The pins are pressed in tight and have four punches to make them extra strong. The chain plates are shaped in a special way to use less material, so the chain is 3% lighter without losing any strength.
Every 520EXR chain is pulled and stretched ahead of time, so it doesn’t stretch too much when you first use it. The X-Ring makes it even smoother and tougher than normal motocross chains. It’s a great choice if you want a chain that rides nice and lasts a long time.
