ZX-12R Chain Tensile Strength???
Anyone know the tensile strength of the 2000 12R stock chain?? Also curious about weight comparisons between ours and aftermarket stuff.
I'm shopping for a new chain to give a little extra at the drag strip, so non-O-ring is probably the way to go. I'm unsure if ANY 520 or 525 chain would be strong enough but I'd consider one if it was.
I talked to RK Chain, but didn't get all the info I was looking for.
I couldn't find a number for DID at their website. :-/ Anyone got it?
Didn't I see that the new 2002 12R is using a 525 chain?!?!
I wonder if it's tensile strength is the same.

This might help...
Tensile strength of 525 & 530 chains
DID Superbike Series
525HV - 9,120 lbs.
50(530)ZVM - 10,400 lbs. (12R OEM chain)
RK
525GXW - 9,300 lbs.
530GXW - 10,000 lbs.
Tsubaki
525 Sigma - 9,460 lbs.
530 Sigma - 10,120 lbs.
I used to be a big fan of RK chains and converted my '97 7R to a 530. RK 530 SHO chains would normally last about 12K-14K miles before the would show signs of binding or kinking. I broke one at a little under 18K. I'm on my third DID chain (which I used to HATE). I replaced the first one at 16K and the second one at about 31K.
Neither of them showed any signs of wear, kinking or binding. I prpbably could have got several thousand miles out of either one. That why I still have both of them saved on my shelf.

I agree with Red Elk. When I first bought the 12r back in 2000 I didnt like the initial stretch of the DID chain on the bike. Knowing the factory chains on most bikes are less than the top quality, I jumped the gun and called the chain a "piece of shit" or somthing like that. Well 2 years later I still have that chain on there and its been great. The initial stretch stopped after 2000 miles and the pin to pin length hasnt changed much sence.
I'm used to the Sigmas I guess. They dont have much if any initial stretch.
I'm going to try a new DID instead of a Sigma when the chain gets replaced sometime this summer.
The rollers are starting to loosten up now but thats "normal" wear, and its comparable to the sigma at 15,000 miles.

Yeah! I also like the OEM DID chains. Just replaced the
original last wednesday and it had over 47000km(29000miles) on it and it didn't look like it was worn out yet. Just replaced it because I'm starting my summer holiday this evening and looking up to 8000km (5000miles) and don't want to get broken chain at 250KPH in the German autobahn. :-)

I will NEVER purchase another RK chain in my life. I dont know if anyone has any experiences with Busas, but there were about 50 guys that had RK chains on their bikes. Some broke, taking out expensive cases, others broke without incident. When RK was contacted about the weak chains, instead of stepping up and trying to fix the problem, RK sent out a letter stating their chains were not meant for highpower streetbikes like the Hayabusa and would no longer honor the warranty on the chains.
DID is the way to go!
