I've had the RK Racing 520 chain on my off-road bike for a few weeks now. It performs well and handles well in tough conditions. My only issue is that I've noticed a little rust starting to appear after some rain rides. Just make sure to maintain it well!

Best Chain I've Used!
This RK Racing 520 chain has been a major upgrade for my motorcycle. The steel construction feels really durable, and the O-rings keep the dirt out. I noticed a significant increase in performance on my last ride. Highly satisfied with this purchase!

Solid Chain for My Bike
I bought this RK Racing 520 O-ring chain for my street bike, and it's been really reliable so far. The 140 links fit perfectly, and I love how smooth the ride feels. Installation was straightforward, though I did have to adjust a bit to get it just right.

Mixed Feelings About This Chain
I installed the RK Racing 520 chain on my dual-sport bike, and while it works well, I had trouble with the connecting link. The instructions weren't super clear, which made it frustrating. Once it was on, though, it seems sturdy enough for both street and off-road!
