What is the difference between a 525 pitch and 520? Is there any gain to either one? I want to change the gearing on my 06 gsxr600. Any one familiar with Loudon if you have a recomedations as to what i should use it is really apprecated. THANKS
Wear, yes. A 520 chain on a ZX-10R will last about a season. Two-and-a-half seasons on a ZX-6R. Strength isn't really an issue, either. As for the other part of your question, that'll depend on the ratios you pick.
