Use Max BMW's parts fiche. It will tell you diameter(width), pitch and length in millimeters.

From which source are you getting 55mm length for a K75 rear wheel bolt? That length differs in the parts fiche at Max and the pitch is right beside it.

There are actually two lengths for Y-spoke bolts. Those made after 08/90 are 60mm but regardless, the fiche discloses all that at the click of a mouse.
