Chaîne "narrow" de qualité
Les chaîne o-ring ou x-ring "narrow" commencent à être rares, j'ai roulé 90 heures sur cette chaine, dans le gros sable mou, la terre, la boue et elle a vraiment été durable à mon avis, la preuve j'en ai achetée une semblable pour la remplacer !
4 étoiles sur 5 car je la trouve dispendieuse...!

This is a good chain.
This is the second of these chains I have bought. I have put the first chain through miserable stuff and it still performs really well. The chain links have become quite flat on both sides and the pins worn down because of how long I've been using it and the aggressiveness of the environment of which it is used (muddy, sandy, swampy watery stuff i.e. northern Ontario). Despite this, all but the master link have remained sealed and still function smoothly. This chain appears to stretch less and more uniformly than previous DID chains I've purchased despite being a narrower and lighter chain. The gold plating keeps the links from rusting, it's fantastic. Installation is mildly more difficult than other chains because the plate of the master link does not press fit onto the pins, the o-rings push the plate against the clip to keep the clip secure, but this means you have to squeeze the link and assemble the clip simultaneously.

Meilleure chaîne à vie..!!
Cette chaîne n’offre pas de résistance au mouvement et ne requiert presque pas d’ajustement même après des séances dans le sable mou.

Great quality and price
My sons CRF250X and my KLX450R need narrow oil ring chains. This one is awesome quality and value and highly recommend it.

How wide is the chain overall? I've been having issues finding a sealed chain to work on my 05 CRF 450.
It's considerably narrower than a standard o-ring chain and should have no issues clearing the case on crf
