I'm changing my sprockets to -1+2 on my 2011 zx6r my question is my buddy needs a new set will my stock sprockets and chain fit on his 2001 zx6r?

you would have to use both sprockets and chain because the 01 is a 525 and the 11 is 520, not sure if the countershaft sprockets are the same, but the rear is the same lug pattern just not same tooth count

Yea he would get it all both stock sprockets and chain.

the gearing will be off and i'm not positive but im pretty sure the counter shaft sprocket is different all togeather...i think stock 01 is a 15/40 and i think 2011 is 16/43... try it, worst comes to worse he has to get sprockets
