So here is my problem, I have 2019 tw200 with 4000 miles on it. I put a DID o-ring chain on it 2000 miles ago and I now believe this was a fake DID chain because I have lost/cracked 2 of the rollers on the chain. I rode for awhile missing one of the rollers before I noticed it and cut out the bad link and replaced it. I’m going to get a new chain but do I need to just replace the sprockets as well to prevent premature chain wear and failure? I don’t really know how to judge sprocket wear. Thanks!
