I think your chain would have to be a 530 (which is what is on my 12). Your owners or shop manual will give a service limit length for a certain number of links (pins) beyond which the chain should be replaced. You can also look at the rear sprocket and see if the ends of the teeth are starting to get pointy which indicates it's shot. Wear is much harder to detect on front sprockets but it's best to replace chain and both sprockets at the same time unless you are just re-gearing. They used to say if you could reveal 1/2 a tooth on the rear by pulling a link pin by hand after adjusting the slack properly, it would be time to change the chain and sprockets, but the service limit measurement is a much more accurate indicator.

If you have a stock setup it's a 525
(I'm not positive on the length but I think it's 110)
Stock gearing is 16-43
(That's if you ride a 99 ZX7 like your sig says)


I'd also suggest a Xring type chain

i saw the number 43 on the rear sprocket. i will count the teeth on my front sprocket when i get home! if it was stock what would the number be for the front one?

if it is stock should i change it. i do not plan on wheelies i just like to cruise around and rev my engine!! jk

For a complete cross reference look here:
http://www.powersportrider.com/cgi-bin/zcatjpg
Pick the street catalog from the list.
Then type in page 1218 in the page space at the top center.
This is the cross reference dealers use for your bike to establish what went on a specific year bike.

For reference the three digits do have significance...

The "5" is the pin center to center distance in 8ths's....so 5/8" center to center.

The next two numbers 20, 25, 35 etc at the width of the roller in 100th's.... .20", .25" .30" enough that your could measure it carefully and see the difference.

IronPony has had some sets on clearnace on ebay for like $80. You can piece a set together for less than $150....if you want to take the time that is. Lots of merchants are scrambling to sell off inventory this time of year.

2fat2fly gave the same cross reference page I would have...the tucker rocky catalog. You'll find the ZX family bikes share rear sprocket mounting pattern, and most of them share the front sprocket as well (if you were to look at all 520 sizes that is).

It's always recommended to change your sprockets too whenever you change your chain.

Absolutly. If your chain is warn at all, it'll wear your sprockets and vice-versa. So If you just change one you may not be eliminating the problem completely and cause premature wear on the remaining/new component. I also know what It feels like not to have the money to do both, but a lot of times you can find deals that will run you ony $10-$15 extra for both, so it isn't to bad if you look.

15/45 will wake the pig right up! At the expense of fuel mileage, of course.

I would just add don't jump at what seems like a great deal. There is one seller on eBay selling a low-priced kit consisting of some no-name chain and a couple of Vortex sprockets. The price is low for a reason. Stick to name brand components and if you have to, order them individually and make up your own "kit". A few extra bucks is worth the piece of mind you'll get knowing the chain isn't going to snap and rip your leg off or destroy your bike.
