RK's new RX-ring chains offer tremendous value, plus true quality and performance for All but the most demanding high performance applications. Pin length in mm: 19.9mm. Maximum wear life index: 750.

Really nice chains. Made in Japan. Make sure you get the special rivet install tool. It doesn’t use a clip.

Chain is good quality and no issues after my first 1000 miles. Install was easy and feels sturdier than the OEM KAWASAKI chain. Cleans easy after rain. I keep mine clean with WD40 and lightly oiled with motor oil.

Product works as intended. Fit my chain perfect.I will say that the link is a bit easier to rivet so don’t use too much pressure. As you can see mine started to chip a tiny bit, but that’s my fault for applying too much pressure while riveting.Comes with master link grease too which is nice, a lot of other options on here don’t.

Bought this chain for my 2002 DR-Z 400 S. The Amazon page said this was not correct but upon checking my owner's manual I found that it was. No trouble to install especially since the old chain, which had only lasted 10,000 miles had broken and I could not find it. You do need a riveting tool to install it. I have put about 150 miles on it and all is well. I recommend it but check your size rather than relying on the "will it fit" feature on Amazon. In my case the chain length was correct for an SM but 2 lengths off for an S.

A trusted brand for quality and durability. The price was good. It was in perfect new condition and installed with no issues. I love the high quality finish on the side plate, it encourages you to keep your chain clean. No problems with any RK chain ever so I expect to not need to use the warranty and keep riding with it for a long time.
