530, correct? not 525, 520, or any other oddball designation. You know ive never given alot of thought to this topic. Does it has to do with link length pin to pin or width or what. Someone here must have an answer
I just came across this as I was posting in another category, but I'll repeat it here anyway. The difference is in the pins and links, but the sprockets are the same. I was looking at a catalog that had D.I.D. as well as Regina, and they both had the recommendations for chain/engine size. They didn't get into 530 until you were into 750 to 1000 cc bikes. I don't care what the OEM was, if I can get by with a smaller, lighter chain that won't be stressed, I'll save the weight and money every time.
