I've been using the RK Racing 520 O-ring chain on my dual sport bike, and I couldn't be happier. The steel quality is top-notch, and I love the added durability. It handles both street and off-road with ease, definitely worth the investment!

Solid chain for my bike!
I installed the RK Racing 520 chain on my street bike, and it feels so sturdy. The 86 links fit perfectly, and the O-ring design has really minimized the noise. I'm impressed with how smooth it runs during rides, both on-road and off-road!

Good chain, but installation was tricky
The RK Racing 520 chain is a solid product, but I had some issues during installation. The instructions weren’t super clear, and it took a little longer than expected. Once it was on, though, it works great for my off-road adventures!

Decent chain but arrived with some rust
I was excited to get the RK Racing chain, but when it arrived, I noticed a bit of rust on it. I cleaned it up and installed it without any problems, and it performs well. Just wish it had come in better condition!
