RK GB520MXZ4-CL Clip Connecting Link for 520 MXZ4 GB Heavy Duty Chain - Gold

Excellent chain that stands up to the rigorous action of motor cross, great price, the gold chain also looks cool.

Strength and longevity on a motocross track is a must, RK mx chains wonr disappoint.

Very good chain! Good quality for the price. Comes greased up with a separate little package for master link. Fit perfectly on my 2001 CR125. Amazon says the 116 links doesn't fit, but my shop manual said it does. So I went with 116 and it fit perfectly. Always consult the service manual for your bike, and you won't have fitment issues.

first time using RK chains after reading a recommendation, i put this chain on a supermoto duel sport and so far it seems to be a great chain

Replaced my chain as the o rings were all cracking and I regularly ride in glacier silt rivers and dry stream beds so it was only a matter of time before the chain wore completely out. I got a clip link as I don't have a chain rivet tool and so I can remove the chain for a kerosene cleaning. Only went on one ride in the mud and dirt so far but the chain is great rk quality. Also 116 links was too long so I took off two links with a cut off disk on my grinder. I have a 13 front and 51 tooth rear vs 14 47 stock and a huge 140/80-18 tire so I wanted the tire as far back as possible. 114 put me at 3 on the snail adjuster and 116 was maxed out with a loose chain fyi.

I bought this chain for my 2003 CR250R that I’ve recently rebuilt from the frame up. I liked the price, gold color, and tensile strength rating relative to other non o ring gold chains (did, renthal). Unfortunately, when it arrived the chain had surface rust on every stamped link. Additionally, while the chain package itself was still sealed, the box was opened on one side and taped on the other. I’ve returned it and I’m not sure if I’ll order another or go with another brand. (Purchased using a family members amazon account).

Have been running these chains for years on my 125 2-stroke. Had no problems with them, they are light and durable. You can just clean with a pressure washer and not ruin O-rings.

The link is fine but the description is wrong. There are no seals. This is not an o-ring chain.
