DRIVER YAMAHA INPRES DRIVE STAR SPEEDER NX M423D

BoostBox

Maximizes impact energy and converts it to muzzle velocity.

Evolution of original muzzle speed-up technology "BOOSTRING" and "SPEEDBOX". The structure around the face suppresses unnecessary vibration at the time of impact and maximizes energy conversion to the initial velocity.

Science of RBI

You can hit with the most flying RBI by scientific sensibility.

Golfers tend to hit what they perceive as the "center of the head height" of the driver. Yamaha paid attention to this and designed the crown shape and face design so that the ball can be hit where it flies the farthest (= slightly above the center of the face).

COUNTERWEIGHT SYSTEM

Largest class lateral moment of inertia for women's models.

A total weight of about 25g is optimally placed on the back and heels, centering on the center of gravity. This achieves the largest class lateral moment of inertia for women's models, and creates overwhelming flight and straightness that is strong against mistakes.

"Good Face"

The shape and size make it easy for ladies golfers to set up and swing, allowing them to swing comfortably.
