    Interesting, I wouldn't have thought there would be a huge amount of weight difference between the two chains and sprocket set, but in racing every gram counts.

    Thumbs up Chain weight?

    IF, you're racing use 520 non O-ring chain and an alloy rear sprocket

    For the street 525 O-ring chain and a steel rear sprocket

    With 525 the weight difference between the heavier O-ring chain and the non O-ring chain is about a pound
    520 will be even lighter

    There is a bit of an advatange to the 520 in the $$$ department too. I've used 520's on both my other RSV'ss without issues, but I also take really good care of my chains and sprockets too.

    Re-firing on this thread as I'm about to get sprockets and chain. Again, former EK guy and Renthal sprockets, but not sure that's the right answer here. Think I'm sticking 525, bike has 15/42 w/520, but I had read 16/44. That still the right answer for a twisty road street bike (for now)? Likely stick steel on the rear, but open to suggestions. Superlite R7 has had mixed reviews as has Supersprox. AFAM is always good? Remember them from years ago and helped form my opinion on French Manufacturing, but I guess over 20 years things change. AF1 seems to be somewhat limited in selection, any advice?
