Hey guys, i'm going through my bike right now stripping the whole thing down and getting everything ready to ride again. I just did my first trip to the Oregon Dunes where we rode for 3 days straight. My chain is garbage now, so i need a new one. My rear sprocket is a nearly new steel one that i run the bush so i think i'll keep that. Basically i'm looking for a good chain for a good price. O ring or X ring doesn't matter to me. I ran a DID non o ring and it lasted me well, until we hit the sand. When i order it do i need a 520, 114 link or something. My bike is a 03 cr250. And lastly, i'm in Canada, so i think i'll order online or look for a deal on ****. Thanks guys
