Chain length for RM 125?

Recommended Posts

Does anybody know off hand in a 114 length chain is long enough for an RM 125 with 12/51 sprockets?

Look on Rockymountain ATV/MC and get the specs for your bikes. Now look at the stock gearing. Now look at the gearing you want. When you go down a tooth, then -1 link, up a tooth +1 link....or just order a longer than stock chain and you got it covered :thumbsup:

What did the box say on it. Sounds like you got a HD520 chain. They are thicker links. No way a 530 will fit on 520 sprockets.
