Ive had two non o-ring chains. One is the one that came with my honda. There is under 20hours of woods riding and its shot. Its been shot. I have to adjust it every ride. Its getting replaced asap. Ive also had the DID MX chain which I thought was o-ring since it was in that section. Same deal as the stock chain. Garbage. PK has been running the regina oring chain on his bike for a while. That will be my next chain. Its 1/2 the price of a did erv3 and lasts much longer then a non oring piece of junk.
