I'm running the EK ZZZ X-ring 530 on four of my older liter bikes. Higher tensile strength than the DID, RK, Tsubakai, or Regina. I've not had to adjust the ZZZ on any of my bikes. Plus they come with two neat little contoured spacers that drop between the sideplates on the master link so you can't screw up the installation by overtightening with your peening tool. My one experience with a RK 530 SO O-ring chain was underwhelming. The steel JT sprockets machined in Thailand were nicely manufactured too.

 

I haven't had good luck with second tier chains from any of the major makers. Currently running RK520GXW, which I believe is the top of the line from them. I have never had to adjust it and it has been one the bike for a few years now, but I don't know the mileage.
Can't tell any performance difference with 520, but tensile strength isn't an issue for any of the chains.

 

As long as the 520 chain is from the highest grade, you should not see much of a diffidence on the life span. In any case this is a matter of preference like the oil threads.... All the good chains work much the same way in both 520 and 530 with a bit of weight advantage for the 520.

 

Totally an oil thread!

Still, I hold to the idea that all other things being equal, a 530 chain will last longer than a 520. A properly maintained 520 will last longer than a neglected 530, but now we're adding outside factors! Also, a 520 sprocket is thinner and more prone to wear. 530 just has more metal that you have to wear through!

After that, it's all personal preference... if you maintain your chain and are less choppy with the throttle and want the performance gains of a 520 (especially at no extra immediate cost) then I say smart move.

If you're like me and commute nearly every day on the bike and don't clean the chain but every two weeks, and am willing to sacrifice extra rotating mass that I won't even notice on the street, 520 may be an unnecessary conversion.

 

True, it's a given, 530 have more metal and probably will last a bit longer, but the little extra miles you can get out of it is most likely not very significant either.
How many times are you going to replace the chain if you maintain it correctly for the life of the bike? if you even going to keep it that long?

In my case, I am ready to forgive the 520 for doing a little less miles for the performance I get out of the light weight. The total package of light chain and light sprockets do make a difference, at list for me that is

 

The importance that you place on that significance is probably going to be the deciding factor in the chain that you buy. Well, unless only one of them comes in the color, price range, delivery time, sprocket size, or brand that you prefer!

Either way, I am not trying defend my choice, just trying to give reasons for both. I wouldn't hesitate to recommend a 520 chain to someone who wanted the benefits from it!


P.S. I'd probably notice the weight, but this bike is more than enough for me as it is so I wasn't too concerned staying with 530.

 

No worries, as I said it is like an oil thread! Your choice is as good as mine

hands down the best deal out there. good 520 chain and great sprockets.
super light super strong steel sprockets. running 4k on mine so far and no problems. i went 2up on rear and love it.

 

Wow that is a great deal! I've been using 520 for about 8 years now, but with aluminum reader I eat through those way before any chain problems. Track days chew the hell out of rear sprockets oh and wheelies are probably the worst thing for them as well.

 

Just to note. On their website there isnt a listing for our bikes, but just call them. They are real nice and they know vtr1000s, so they will get you what you need. Also you can specify what tooth combo and they can get you that. The rear sprocket is a pretty good one for steel. It hard anodized too I believe.
Yeah its way better than the aluminum sprockets.
Like I said the chain is a pretty good one too. Just keep it clean and itll last.

 

If you going to continue using Aluminum sprockets, use only AFAM the rest are pretty much crap. AFAM using the correct technology to make the sprocket allot stronger. Or just get the Superlite sprocket, very small difference in weight but will last you as the chain.

 

how much difference will you see between the 530 and the 520?
