It fit on my 2009.
I bought the 12t too

 

Uhh correction. It shows it is out of stock until 1/30...

That would be my fault, they think I want one, and my luck is at work here.
Perhaps when anyone else looks it will be in-stock

 

Hello all first time poster here but I have been reading a lot of good stuff on here.I was just wondering to the people that has used the 12th How much top end did you lose and the same for you that have used the 13th? Just wanted some input before I buy thank you all very much these forms really have helped me out.
