Do you mean 15Tooth?? If you are changing over to 530 then a 15T will be tiny, ok if your building one of those stunt bikes that lives on the back wheel though!!

Dug out the receipt for the ones i bought from M&P but un-helpfully they dont have the part number. The sprocket number is 528.17 or JTF528.17
A google searh of this number will find you any number of suppliers for about £20.
example https://chainsandsprockets.co.uk/produc ... nEZTnqlnzn
This is the 17 tooth, 530 chain size, approx. 12mm offset, dished standard sprocket for a ZZR1100C or thereabouts. I have had three of these sprockets and they are perfect but slightly too narrow at the mounting so you will need to order three of the castlated locking washers. Two for behind and one for in front!!!
Genuine ones still available if you want to go that way
