I wouldn't be comfortable pulling the fork blades together by that much. It could stress the fork crown and cause serious problems. You don't your wife to have a bad crash.
I thought it was odd too because I figured these bikes would have a similar front spacing. So I googled it and on Sheldon's website He listed those spacings and they measured within a millimeter of what he said. This Panasonic was without a front wheel when I found it. The fork does not appear bent and everything looks straight and true but I suppose it's possible the front blades got squeezed together a couple millimeters at some point without the wheel in there. So maybe it's actually a 100 mm spacing?
