Mike, those 21 and 23 agitator wheels look pretty dang close in the pictures.
I am pretty sure a 21 could be run with nothing more than lower the front an inch, and maybe a slight tilt of the stock front fender.
I think from what I read Pickard makes a triple tree so you can run a 23 with out cutting the neck.
I would love to do the 23 on my 13 CVO Anniversary King. I want to hear some reports of how well they handle with this set up. I have a done some work on the motor in the bike.
I do not want to loose handling as I live in East TN, the Smoky's and the Dragon are my back yard. I know I loose nothing the a properly set up 21 as I have that on my fatboy.
What are your thoughts, would I loose handling with the 23 over a 21?
