Years ago, and things might have changed for the better, I bought a chain that rhymes with sooooobaki. New chain, new sprockets. Installed, started stretching immediately. At 3000 miles, started losing rollers. So I removed it and the dealer I bought it from sent it back. I got a reply that there was battery acid on it. So I looked under the bike, and the battery drain was on the opposite side away from the chain, and there was no battery acid damage anywhere on the bike, not on the swingarm, not on the battery box, not on the sprocket or the wheel, or anywhere else for that matter. They said I was SOL on the matter. So I bought the DID ZVM (I think that was the model, it was the most expensive one they had). I used the same sprockets. I never had to replace it again, it never needed adjustment (when I changed tires, I just yanked the axle and didn't touch the adjusters), and when I sold that bike at 60,000 miles, it was still cool. I put the replacement chain on at 25,000 miles.
Now to my current Ducati, and the YZ450F that I just got rid of. Same thing, put the DID ZVM on both bikes, the Duc had 12,000, the Yamaha stock chain went away in less than 200 miles. I put Stealth steel over aluminum sprockets on both bikes. The YZ went 2 years before I sold it, and the chain was still tits, the Ducati is coming on 25,000 miles, and it hasn't needed to be adjusted, and is looking good.
I won't use anything but the best DID they make. And yes, years ago, I had a chain blow through the cases on an old dirtbike I had, I tend to keep a close eye on chains now.
