The center bore isnt the actual size of the bloody hole I know that,what Im saying is that halfway from one stud to halfway to the furthest stud is how you measurer the center bore which is 120mm for a 5 stud pattern.This part of the wheel is called the center bore.
I didn't mean to start WW1V but the center bore I was referring to is the hole that sits over, (or locates on) the bearing hub. Bear gave the size as 69.5 for the VT and I believe the VS is the same except for the part the brake disc locates on which is larger. Pax. Maybe should have simplified it by saying "the hole in the center of the wheel"?
