--------------------------------------------------------------------------------------------
Offering exceptional trajectory consistency to all golfers. Featuring Yamaha’s unique adjustable weight.
The RMX VD weight system allows adjusting the impact stance while maintaining the 5,820 g・cm² moment of inertia, the maximum allowed by rules.
It makes an ideal square impact and high trajectory consistency available to all golfers.
New functionality offers exceptional trajectory consistency
Featuring the “RMX VD Weight System” (* Patent Pending)
“Offering a square impact to all golfers.”
Using Science and Feel to Hit the Ball Where it Flies the Farthest
Golfers subconsciously tend to try and hit the ball at the point they think is the vertical center of the club. Therefore, considering that tendency, Yamaha designed the crown and face shape so that the area that is subconsciously recognized as the center matches the location that results in the longest flight (optimal impact point), which is slightly above the face center.
In addition to increasing the overall head height by making the crown slightly more bulbous, adjustments were also made to the crown-face boundary design and to how the score lines appear. The head was designed so impact points are centered in the upper portion of the club face.
Higher kick velocity (1)
BOOST RING Technology
The series of ribs from the crown to the sole is integrated with the hosel to form a ring that is secured near the face. Ensuring the deflection from impact is distributed uniformly in all directions concentrates the energy at the ball to increase kick velocity.
Higher kick velocity (2)
Lighter Face
The face weight was reduced 12% by optimizing the material thicknesses in the face area. That reduced residual energy in the face and increased power transmission efficiency.
