525 or even 530 chains do last a lot longer.

The best wearing chain i've heard of is the DID ZVM-X

In 520 DID rate both that and the VX2 at ZVM-X at a chain life index of 3500

The 525ZVM-X is rated at 4000 or 14% longer

On my previous 750 super tenere i've been running both 525 and 530 after

DID 520 VM 15417
DID 530VM Gold 28050
DID 525ZVM Gold 23099

And a AFAM DC 520 MTX only lasted 6033 before it was completely shot

On my small pony (xt660z) both the original and the first 520VX2 lasted ~20.000km and i'm on the second 520VX2.

Since the 525 is heavier than 520 i guess that i will go with a 520 again the next time. But i'll prefer the 520ZVM-X over the VX2 since i think that it will last better.

I might also go with the 525ZVM-X but will not pay more than the +14% extra as it is the expected added life.

If i was to go for a long overland trip i would definitely go for an extra bearing in the rear hub and 525ZVM-X - just for the piece of mind of riding of the strongest chain with the best wear resistance.

On my former XT600Z i've had CZ and RK chains fall short of expectations. The RK 520 XSO only lasted 8000km and the first CZ 9000km. The link of the second CZ failed after only 4000km

So since then i had only been DID endless x-rings chains for me ...
