mvxz comes in 520. EK makes several types of 520.
i have an EK mvxz on a 190hp race bike and it holds up perfectly fine

when I was looking at buying a chain I bought the best wear and strength that was offered..seems as if buying the best offered online ...seemed like a good thing ...buy what you think might be over your needs....maybe they offer something not online that might meet your needs..

you beat me to it.



I got a 520 RK GXW haven't with Driven sprockets from motomummy but haven't installed it yet because it's too cold here, But when I do i'll post some pics and let you know how it works.
did erv3 states upto 8400 lbs, rk gxw states strength up to 8800 lbs while ekmvxz up to 9400. not much difference, but every little helps.

The DID ERV3 X-Ring is what you want. This is a race chain and used by most factory race teams. They claim it is the strongest, but who knows. I've never had a problem and I switch sprockets regularly. On the downside it's one of the most expensive and it is gold in color. Can't go wrong with DID. Good luck.

did erv3 is only rated for a 750cc bike as well. If anything happens you're 100% on your own. the rk gxw and ek mvxz are both rated for a 1000cc bike. All the racers who are sponsored by DID and most likely every other chain manufacturer are required to replace their chain every race. What applies on the track when it comes to drivetrain doesn't apply to the street at all. Same with sprockets. They change them out every race. EK/RK are what I would recommend for anyone who isn't racing competively and if you are then go with the erv3 if you want to save 3 ounces of rotating mass, but that's all you're saving and they are the most spendy.

EK/RK are what I would stick with for the added stength and wear life. I'm not saying the ERV3 is crap as it's a damn good chain and great for competitive racers who want to save every ounce.

More so then ANY of this is maintenance. A well taken care of erv3 or even a weaker chain will outlast an ek mvxz if it's taken care of better. Too often a chain/sprocket gets a bad rep when the only thing that should have the bad reputation is the owner who never cleaned/lubed the set up or set the chain slack. this is the #1 factor on how long the chain/sprockets last.

fz1: call them and ask them what % any of their products are in titanium and ask for it in writing.

then call rk, did, ek, driven, drive systems, sprocket specialists, or any other reputable company and ask them about that chain, their sprockets, or even krause racing. I bet you'll get some shocking replies the minute you state "krause racing" and then you'll realize why not one street racer on the planet uses their stuff.

I will call today. I have never looked into the Ti setup other than to think it was a cool idea if done correctly.

I ran a did chain on my 520 setup and it lasted about 8k miles of hard street. I went back to 530 only because I was stuck at my folks place (800 miles from home)and couldn't find 520 sprockets and chain in a -1/+2 setup that weekend.

I spoke with the guy at Sidewinder Racing and will order a set of Ti sprockets and the Sidewinder 2 chain. I am getting the 16,000 version. The 16k is the lightest as it has the highest amount of titanium in it.

The chain and both sprockets came to $430. The sprockets come with a lifetime warranty and he said if they ever show any signs of wear, just take a picture and they will send me a new one. The chain is warrantied for 1 year not to stretch, he said he's had the same chain and sprockets on his CRF450 for 5 years now and the chain has never moved.

It's a little more than what I paid for my last 520 setup and got maybe 8k miles out of them. So if these go for at least 10k, I guess I break even.

Based on what the guy told me, the links are a mix of metals and the rollers are titanium. He said that the rollers are often too hard for regular sprockets, so they only recommend running the chain along with the lifetime sprockets.

The weight isn't listed, but they said the 16k is the lightest 520 chain on the market. If it's actually rated at 16k, that's what matters to me.

Since I don't have my R1 yet, I am putting these on my Speed Triple. Should be interesting. Guess I'll weight it when it gets here and see what happens.

weigh it before you install it if you would. Also weigh the rear sprocket please. I would like to compare it to a normal weight steel sprocket and name brand chain. it's an alloy rear sprocket and if it weighs the same as a steel rear sprocket then you'll know it's just a steel sprocket. I'm very curious on the weight of both of those. Been trying to get the weight of them for a long time.

Super Steetbike did a comparison a while back.

Sidewinder Titanium II
The Titanium II sprocket is 100 percent guaranteed not to wear out. Made of a Ti-moly material, it is enhanced with molecular boron for increased hardness. If it wears out, send it back for a replacement for the life of your bike. You can't beat that!
Weight: 1.85 lbs.
They list the stealth at 1.8 lbs. id that means anything.

Personally, I could give a damn what it's made out of if it doesn't wear out. They could use dead kittens for all I care if it means I get more than 8k miles out of it, I'm a happy bastard.

i just emailed them in reference to weight, strength and if they recomend running them on stealth. we'll see what they say. that 10K for 99 aint bad. ek goes for 100 on bay and rkgxw 96. heck even 12k for 119.

my 530 stock started showing wear after 4kmiles, a year ago, and its time this summer that it goes.

most people get more then 8k miles out of a normal alum 520 chain kit if it's taken care of. I average about 15k miles out of my 520 chain kits. with a steel chain kit the average is about 20-30k miles out of a 520 chain kit. That is unless you stunt then of course the lashing of the drivetrain doesn't make it last nearly as long. Unless it's all race miles or stunting something caused it to wear out that quickly and I would look for the cause of it. That's the one problem with steel chain kits...They can hide abuse well and often because the sprocket is so strong the chain will go instead of the sprocket and if that happens it normally costs a lot to fix the damage a loose chain will cause.
