Center of gravity has both a horizontal component and a vertical component. The
vertical
center of gravity
(VCG) lies along a line 38 inches (~97 cm) from the bottom edges of the fork pockets. Similarly, the
horizontal
center of gravity (HCG) is located 8 inches (~20cm) from the front edge of the vertical support.
