Just asked Scott at Talon and they don't do a 12T. My guess is that you will have to buy one in from the States.

12T is cruel to the chain though cry

Hello Mate,
Thanks for the reply. I only want the 12t as a short term thing. Someone has put 44/13 on it and I wanted to get the life out the chain before replacing it if that makes sense

Changing your gearbox sprocket to a 12 tooth one will not save your chain any no - in fact the smaller turning diameter will wear your chain out quicker. hmm

I guess you are trying to gear down for the lanes?

There are a couple of 12T sprockets on US eBay but shipping will be the killer. See http://www.ebay.co.uk/itm/YAMAHA-N-O-S-COUNTER-SHAFT-SPROCKET-12T-TTR250-PT-610-12-/360731980109?pt=Motorcycles_Parts_Accessories&hash=item53fd4d314d as an example.

 hi, I am trying to put a 12t to make it closer to a 47t rear as I would rather use the life in the chain and rear sprocket already on it and then I will change the lot for a 14/50 or such like
