Unfortunately, my RK Racing chain came with a bent link, which made installation a hassle. I contacted customer service and they were helpful, but I still had to wait for a replacement. The quality seems good, just wish it hadn’t arrived in that condition.

Solid chain for my bike
I bought the RK Racing 520 O-ring chain for my street bike, and it’s been running smoothly. The 104 links feel durable and the steel construction gives me confidence for both street and off-road rides. Installation was a breeze, and I could feel the difference in acceleration right away!

Not what I expected
I was excited to try the RK Racing O-ring chain, but after a couple of rides, I noticed some wear and tear faster than I thought. It connects well and looks good, but I hoped it would last longer considering it’s meant for both street and off-road use. Just okay for the price.

Exceptional performance!
I’ve been using the RK Racing 520 chain on my dirt bike for a few weeks now, and I can’t express how happy I am with its performance. The 104 link design holds up great on rough terrain, and the O-rings keep everything running smoothly. Highly satisfied!

Good enough for everyday use
The RK Racing 520 chain works fine for my daily rides on the street. The links are sturdy, and I like that it’s designed for both street and off-road. However, it doesn’t feel as premium as I expected, but it gets the job done.
