King X750 Cupface Titanium Custom Golf Driver:
With the King X750 Golf Driver (Callaway® XR™ Style) Speed is everything, and it's the driving force behind the KING X750 Driver. That means speed comes from an aerodynamic crown, from the MOTO HIGH M.O.I. face, from a maximum shaft load, and the list goes on and on.
Our engineers traveled down a new path to make a driver that's a proving ground for these great technologies. If it increases speed, it's in KING X750 Driver, and that's why it's our fastest titanium driver ever.
Speed from Speed Step Crown
To reduce drag and maximize speed through the swing, KING X750 features a Speed Step Crown and combined it with an optimized aerodynamic head shape. Everything about this driver is optimized for aero efficiency, which is critical to add speed with less drag.
Speed from KING MOTO Face Technology
X750 increased ball speeds across the face by reducing 10% of the face weight to make it thinner. MOTO leads to more energy efficient energy transfer all over the face, allowing Callaway to put the center of gravity (CG) 17% lower where most golfers want it, therefore delivering higher moment of inertia (MOI).
Improved head shape gives you more ball speed on shots hit on the center of the face and on -off-center shots as well.
Cup face design enlarges the effective face area and sweet spot. The benefit is increased rebound effect for more distance.
