csoto23,

If you go up three in rear, you will need a longer chain. I have gone down one in front, and the chain did not rub the guard.

ninjanick,

When I replaced the stock chain, I went two up in back with the brand new chain and sprockets. They fit easily with the proper slack. For the street, I like that change better than one down in front.

If you like, I will be happy to send you a nearly new Sprocket Specialists 42t aluminum rear sprocket.

ninjanick,

I am sorry I was unclear.

I replaced the stock chain with another of the same length. My point was that a new 108-link chain fits the stock front and a 42t rear sprocket.

My model year is in my profile but is irrelevant because all ZX-6Rs have the same stock gearing and chain length.

The standard aluminum sprocket is not hard anodized. I replaced it at a couple of hundred miles to fit a 520-size counterpart. Put another way, I would be worried about hastened wear on the sprocket, not the chain.

If you are unhappy with the sprocket, it will make a great (and quite light) paper weight. It is not only very reasonably priced, it is free.
