Okay, I know you have a ZX7, I don 't know the year...
I know the front is a 520-16...what's the rear? I'm guessing 40-42... BTW my guy doesn't have any but there are a ton on EBAY! I saw a chain and rear sprocket for $32 BIN.... You shouldn't have any problems finding a deal but if you need help, I'll be glad to assist you!!! On your sprocket, it should say how many teeth are involved.
