I installed this RK Racing 520 chain on my street bike and it’s been fantastic so far. The 96 links fit perfectly and the O-ring design keeps the dirt out while maintaining smooth operation. Definitely worth the investment if you ride both on and off the road!

Arrived damaged, not impressed
I was excited to get the RK Racing 520 chain, but it arrived with some links bent. I had to straighten them out before installing, which was a hassle. Disappointed because I expected better quality control for a brand like this.

Good but tricky to install
The RK Racing chain is a sturdy piece for what you pay, but I found the installation a bit tricky. The connecting link took me a few tries to get right. Performance seems solid now, but I wish the instructions were clearer.
