O ring chain

[Aussie scott]

I was inspecting my chain today and noticed a broken o ring hanging out, dose this mean the chain is at the end of its life or has it got a little time before it needs replacing, ive travled 20000 kms on this chain so maybee its time for a new one anyway, has any one had this happen before and had the chain last a little longer?

The O ring retains lubricant within the chain, so you might get it to last, with care and plenty of lube.

My o/e chain failed at 7,000 miles so you've done well at 20,000 kms.
I fitted a replacement X ring chain along with a chain oiler and that's done 18,000 miles and still going strong

Keep an eye on the spot where the o-rings have failed...look out for seized links or a tight spot developing...others wise keep it lub'ed and adjusted and, assuming there's no other damage or excessive wear, keep riding!

thanks for your reply robell and grumpy, will keep a close eye on the chain, seems to be in good condition apart from the oring broken, have heard of many chains failing earlier on the zumas, perhaps is due to diffrent climates i.e salt on the roads in the uk
