I know there are plenty of 520 chains with tensil strengths that equal and surpass that of the stock d.i.d. 530 on the DS, and the only downfall I can think of going to 520 on my bike is accellerated front sprocket wear. I already hook teeth after 100 hours as is, my question is how long does a high quality tool steel front sprocket last on a stage 2 DS that loves to slam wheelies with an accelerator pump everywhere it goes running the narrower width of a 520 chain?
Thanks,
