ok, that stupid advertising pop-up has GOT to go! Like any of us are interested in a designer purse... better yet, the stupid ad doesn't re-direct properly! What's the deal? This just started today, AFAIK...

Sixto,

The sprocket doesn't need to be replaced, unless the teeth are worn, which is not usually the case. But it wouldn't hurt to replace it, especially with >200kmi. I don't think I've ever seen a failed 60x tensioner (yet), but it wouldn't hurt to replace that either. For the record, I did not replace either of those items on my cars... only the chain. I did use a new OE master link, with a press-fit center plate. The aftermarket links typically have a slip-fit center plate.
