The variation of the kinematic and dynamic moments of inertia and the bandhead moments of inertia $J_0$ systematics of superdeformed (SD) bands in the $A\sim 190$ region are investigated, which turns out to be helpful in the spin prediction of SD bands. The spins of about 70 SD bands in the $A\sim 190$ region are predicted by these approaches in combination with the usually adopted best-fit method. The $J_0$ systematics seems to be very useful to the understanding of the properties of excited SD bands and the implication of identical SD bands.
