I would not trust any information on that website, too many errors.
you can measure for yourself like this:
Take a string or narrow slip of paper, wrap around the fork where you want to measure, mark where it overlaps.
Lay the string or paper out flat and measure from the edge to the mark in mm.
Divide your measurement by 3.14, result is the diameter.
43mm is the correct answer for a Vegas or Vegas JP. Hammer and Kingpin are larger.
Every day is a good day to ride. Some days are just better than others.
