Fork swap bearing question
'12 versys, swapping a cbr929 front end on.
The 929 forks are too big for the verses lower triple. So if i were to bore out the verses triple I would not have to find new bearings. However, I have no idea how to that or where to get it done. The spacing is the same so this would be ideal as I can use the 929 axle and brakes without modification.
So Ill need to swap the triples from the 929. Heres my dilemma. The bearing dimensions for the versys are:
TOP- ID35/OD55/W14 BOTTOM- ID35/OD55/W14
The 929: TOP ID26/OD47/W15 BOTTOM ID30/OD55/W17
So I need a top bearing that is ID26/OD55/W of 14 or 15
and a bottom bearing that is ID30/OD55/W14 or 17.
So the ID and OD are easy enough - ID is the thickness of the steering stem, OD is the diameter of the bearing to fit the neck. Im assuming the W or width is the height or thickness of the bearing.
Any thoughts on the thickness of the bearings? Measuring from the top of the bottom races the length is the same for the 929 and versys, though the threading is different.
Or I can have the verses stem put into the 929 triples and use the versys bearings. A lot simpler but I don't have a press or tig welder to do the swap, not to mentioned the versys team is a lot thicker.
