The 60mm offset is from the center of the steering stem to the center of the forks. the 182mm is the width of the forks. center to center.
182mm = CB550, CB750 K/F
172mm = CB350F CB400F
60mm offset = CB350F CB400F CB750 K0 K6
50mm offset = CB750F
45mm offset = CB550
Less offset = slower steering, more stable in a straight line.
More offset = quicker steering, less stable in a straight line.
Dropping the forks in the tree= Quicker steering, same as raising the rear ride height.
That's all I got for now.
