Hey guys, I need a new set of sprockets and a chain for my '98 CBR 900RR. I've pretty much decided im going with a DID chain and steel JT sprockets. The dillema is that my bike originally has a 525 pitch chain and sprockets, but im not sure if its worth getting the new kit in the 520 size. I know its lighter and supposedly faster because its lighterweight. I know the steel sprockets and DID chain are rated capable of the 900RR's power even in the 520 pitch. Is there anything to lose by going to a 520 size setup?
