RMX VD40 Iron

A new generation of iron that breaks the mold in every way, both in terms of performance and shape.

A truly good-looking iron is one that sticks the pin.
It compensates for mishits to minimize flight distance losses and inhibit deviations to the left or right. It hits the green so consistently, it’s boring.
Introducing a new iron with a huge 4,000 g・cm² moment of inertia from another dimension.

The innovative shape results in a 4000 g・cm² moment of inertia that offers a whole new level of performance.
It sets a new standard for irons.

The huge 4000 g・cm²* moment of inertia, unrivaled by any brand, was achieved with an extreme weight distribution that concentrates the club mass at the toe and heel, which are the farthest points from the center of gravity. That greatly eliminates mishits, which leads to hitting greens in regulation more often.

  • *7-iron moment of inertia measured by Yamaha Golf was 4,041 g・cm².

A breakthrough in course management.
The 4,000 g・cm² moment of inertia enables aiming directly at the pin.

Even if the ball is not hit at the ideal contact point, the 4,000 g・cm² moment of inertia, the largest available, significantly reduces any distance losses and inhibits left-right deviations to prevent losing due to mishits.
Machine measurements of a 7-iron indicated left-right deviations of about 9 yards and vertical deviations of about 13 years at a distance of 150 yards (according to a Yamaha Golf study), which confirms the claim of always sticking the green.

Both the left and right figures indicate machine test results from hitting the ball with the impact point shifted 5 mm below the sweet spot or 15 mm toward the heel or toe.

  • *The figure on the right indicates average values calculated from five hits at each point (centered at 150.0 yds)
    (according to a Yamaha Golf study).

Revolutionary Shape Offers a Beautiful Orthodox Look the Moment You Address the Ball

The neck shape appears to protrude significantly when viewed from the back face side. That form is the result of pursuing function. However, that prominent protrusion completely disappears to provide an orthodox appearance when addressing the ball, resulting in a somewhat larger face size that inspires confidence.

Rib delivers a satisfying hit feel

A solid rib structure positioned in the club cavity increases body rigidity and provides a satisfying impact feel.

Caution

External pressures can dent N.S.PRO 850GH neo(R), which can cause bending damage. Handle such shafts carefully to prevent external pressure forces that could result in dents or other deformation.

In particular, beware that pulling clubs out of caddy bags at an angle could cause deformation from the grip catching on the bag opening.
