Great for Mixed Use
I've been using this RK Racing chain for both street and off-road riding, and it holds up really well. The steel construction feels solid, and it handles tough conditions nicely. A good value for the price!

Decent Chain, Some Installation Issues
This RK Racing chain does a good job on my motorcycle, but I had a bit of a struggle setting it up. The connecting link was tricky for me to get right. Still, it works well once it’s on.

Not as Expected
I was excited about the RK Racing chain, but it arrived with some rust spots on it. It seems to work fine now, but the first impression was disappointing. Packaging could’ve been better too.
