I´M TRYING TO FIND A SET OF USED UPPER FORKS FOR THIS BIKE HOWEVER IT SEEMS TO BE A DISCONTINUED PART THROUGH HARLEY, SO I WAS WONDERING IF ANYONE COULD TELL ME WHAT SIZE MM THE FORKS ARE SO WE COULD TRY TO FIND A USED PART OF SOME SORT THAT COULD BE USED IN PLACE OF THE PARTS THAT ARE ORIGINAL TO THE BIKE??
