The Titleist 907D1 is a multi-material 460cc driver with a high moment of inertia (MOI) for increased DISTANCE WITH FORGIVENESS and outstanding playability.
MOI is the clubhead's resistance to twisting on off-center impact (i.e., heel, toe, high, or low). A higher MOI value means more resistance to twisting. The benefit of a higher MOI is longer distance (better energy transfer from club to ball) on off-center impacts.
