how many teeth does the stock rear sprocket have on an 03 636?
the front has 15 right?
what's the difference between a 520 and 525?..which does mine have stock?

You rear sprocket has 40 teeth.
The front is 15 teeth.
It has a 520 chain.

The difference between 520 & 525 (other than price) is that the links are wider on a 525. This makes them heavier.

I was so happy to see a 520 chain on the 636.

He's a fountain of knowledge. Now where did I put that rubber stopper?

Your chain says right on the side plates...and the rear sprocket also says 40 on it....just look closely & you will see it....for the future.

How much lighter is an aftermarket 520 chain compared to the stock one? Is it significant enough to want one? I just was considering one since the stock one seems to rust very easily in Hawaii. Yes, I lube it frequently.

I recently did a 520 converson using a DID 520VM chain, Renthal ultra lite front sprocket and Sprocket Specialist hard anodized aluminum rear sprocket. The total weight saving over stock was 2lbs 2ozs. Most of the savings was from the rear sprocket. I think the difference in chain weight was about 8 ozs. I don't know why a 520 chain would be any less susceptable to rust.

Most of the aftermarket chains I see has a gold plating to it so I figured it would rust as easily. I didnt mean to imply that the size had anything to do with the rusting. My bad.

oops again.

Only the side plates are "gold" plated. They probably won't rust as bad but the rest of the chain is about the same. You can also get them in colors including green. The '04 ZX-6RR is supposed to come with a green 520 chain.
