Try Chris tombleson at Grumpy 1260. I got mine off him in the past

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.

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

What size of rear sprocket did you use ? And what length of chain?

CMSNL has the rear sprocket at 41 teeth but i dont see the number of links in a standard 630 chain.
No matter, to convert a 41 tooth sprocket from 630 to 530: divide 41 by 5 and then multiply by 6.
That gives you 49.2 teeth for the replacement rear sprocket at the 530 chain size.
The front sprocket at 15 teeth would be treated similarly and dividing 15 by 5 and then multiply by 6 gives you 18 teeth for the front sprocket at 530 chain size.
You are looking at buying a 17 tooth replacement.
A complete guess at the chain links number for a Unitrak 1100 is 110 links at 630 size. 110 divided by 5 and multiplied by 6 would give you 132 links for the 530 chain size just as an example.
Substitute your own number above.

Mine is not a Unitrak 1100 so not very relevant.
