Does anyone know the torx size to remove the triple trees from the frame neck? I know for a fact it's not a T70 or T50.

 

Just walked out to my bike and checked. It is a T55 on my 2013 Iron, should be the same for you. I have also taken my tripple trees apart to repack the steering head bearings so Im sure that is the one you are speaking of.

 

Thank you. It's the largest Torx bit I have besides a T70 that I used for my screaming eagle comp bolt. Glad I didn't have to run out and buy another socket/bit.
