I was really disappointed with the RK Racing chain. It worked fine at first but then started skipping after just a week of use. I followed all maintenance guidelines too. Not the durability I was hoping for from a heavy-duty product.

Excellent Performance in MX
This RK Racing 420MXZ chain is a beast! I've been using it for a month on my YZ250F and it's held up wonderfully. Smooth shifting and no issues with stretching. Highly efficient for motocross racing!

Solid Chain for My Dirt Bike
I bought the RK Racing 420MXZ chain for my Honda CRF250R and it's been fantastic! The heavy-duty steel feels super strong, and I’ve noticed better acceleration on the track. Installation was straightforward too, just followed the instructions and it fit perfectly!

Decent Chain, But Difficult to Install
The RK Racing chain is durable and seems well-made, but I struggled a bit with the installation. The connecting link was somewhat tricky to get on. Once it was on, performance was good, though. Just be prepared for a bit of hassle!

Not a Great Fit for My Bike
I had high hopes for the RK Racing chain, but unfortunately, it didn’t fit my Suzuki RMZ450 like I thought it would. The quality seems solid, but I ended up returning it. Make sure to double-check your specs before ordering!
