Hi i have an earlier post about changing sprokets and have decided to go down 1 in front and up 2 in rear. So i went out to look at my bike and was wondering how many teeth o.e.m front and rear have cause I know they have been changed before and dont want to change them out if they dont need to be. I know some people will say that you would feel a difference but whats on it now is what im use to thanks o and its a 97 gsxr 600
thanks
thanks
