Ok Chain
I race Harescrambles and this chain only lasted about 6 months. Had it break on me during a race. My buddy had the same chain and it broke in the same spot. Back to xring chains!

Primary Drive 520 RDO O-Ring Chain
Very impressed with this chain, has not needed adjusting since the first couple rides. About 30 hrs on it so far, MX only, will probably last another 20 at least. I will get their X-ring chain next time, less rolling resistance. Very good value from Primary Drive.

Is the chain lubed for use out of the package, or is that just packing grease?
Cody H on Sep 30, 2016
BEST ANSWER: Use the chain out of the package as is. After your ride and you do your maintenance, clean your chain and lube with your favorite chain lube for o-ring chains.
Is this master link, Part# 1021270020, compatible with this chain:
Primary Drive 520 ORH X-Ring Chain 520x112 - 2003 Suzuki DR-Z 400

GREG on Sep 6, 2016
