Best chain?
 

What do you rate as a good chain?

I got to change mine as now other people have noticed it's Knackered as well:o

I've only used a few brands of o-ring chains and rate their durability as follows.
1) Regina OR - very long lasting, chain remains flexible until worn out (I've had two of these)
2) RK EXW - very long lasting, chain remains flexible until worn out (I'm on my third one)
3) Primary Drive - long lasting, chain gets very stiff over a short time (I've had two of these)

Regina and DID

Here are the numbers...

RK RX x-ring replaced at 2515 miles
RK GB520GXW x-ring still running at 2582 miles - almost no stretch
Primary Drive o-ring replaced at 1773 miles.

I have had the best luck with DID X-ring...

I've read allot of very good reviews of the DID 520VT2 X-Ring chain. These are a slightly narrower X ring chain (came stock on the Honda 250X) and fit through guides easier and seem to be pretty low friction and quiet.

I read this and have since been using RK XSO.

I'm convinced.
