As usual, I'm with the Dogg. 30+ years of riding, never broken a chain. A lot of the time I was too poor to buy a good chain, bought a cheap one. Even then, I'd run it until it stretched, then take a link out and run it until that one stretched it's full swingarm slot length. Then change it. Never, ever, broke a chain. With todays o-ring chains going 20 thousand miles +, chain is absolutely no problem.
