I created this awhile ago to help me place the correct origins for the bike Jm's
It's nothing special but it will allow you to correctly place the pivots and orientation for the frame, swingarm etc.
It's pretty straight forward to use, line the cylinders up with the points the pivot then assign the orentation to the cube attached to that.
Any Questions, just ask.
Special Thanks To:
JVDL for the pivots diagram.
