Just to give a thumbs up to RK.
No concrete evidence was found to suggest that fake RK chains are available. But if in the future if I find something new, I will update. And of coarse if anyone else comes across new
evidence, it would be great to hear about that.
I will be sticking with the RK 520XSO chain. A great chain for the EX
. It has a tensile strength of 8,300 lbs. Designed for bikes up to 80HP. The gold version and colored versions would be cool looking, and you would not be down grading the quality of the chain by using one of these, as they too have the exact tensile strength of 8,300 lbs. (Also good up to 80HP.) I would be leery of using the regular "O-ring" chain, as it only has a tensile strength of 6,900 lbs. and designed for bikes up to 60HP. While the 60HP would still be within the spec of the EX
, a little too close for comfort for me. They even go on to say it is really for bikes 400cc or less. With the X-ring chain (XSO) good up to 750cc. It would still be OK to bump it up a notch and get the Z-ring chain, don't have the specs in my head but can be found in the link a couple of post's up. For me, since the specs for the X-ring fits well with my bike, I'm good with that one.
On a side note:
In all this I did manage to learn a new way to determine when a chain needs to be replaced. Looking at the square shapes on the end of the pins, if 1 or more isn't lined up parallel to the others, then the chain needs to be replaced. I just thought I would put that out there, it was a new one on me.
To the member that sent me a PM on this subject, I will keep you anonymous for now since the communication was made via PM. I think you made a very wise decision to go with the RK Z-ring chain. As your riding a much more powerful bike than I am, I would have made the same choice
. I may end up talking you into a meet up at the Tail of the Dragon next year, hey it could happen
. I have all the confidence that Z-ring chain will get you there, back, and then some
