my son has a 2009 st deluxe need to know how many teeth the stock rear pulley has want to get him a chrome one for xmas

 

I'm quite certain it's 66 tooth for the newer rides.

 

2007-2010 use a 66 tooth rear sprocket.

 

sounds right ^ Thats a fine lookin k-9 man

 

" what a long strange trip it's been . . "

Your Fuking right about that.

 

09" takes a 66

 

+1 on that.

If your getting a 3rd party sprocket you may have to get it fitted and measured for a pulley spacer. A stock chrome Harley pulley probably will bolt right in. I had to use a .200 spacer for my chrome pulley from DNA for my '07 Heritage.
