Caliper brake bleeder size?????

I'm going to install Goodridge Speed Bleeders on my 2004 Yz450f. These replace the regular brake bleeder nipple, with a unit that has a checkvalve so that you can bleed the brakes without somone else to assist you.

My question is what size are the threads of the stock bleeder nipple??

Goodridge shows:

7 mm x 1.0

8mm x 1.25

10mm x 1.0

I'm guessing the Yamaha uses the 8mm x 1.25, but I'm not sure.

Any help appreciated.
