1Higher Initial VelocityBall’s initial velocity boosted by 1.7 m/s

The club head is equipped with the Multi-Beam Cup Face II, which bends inwardly uniformly across the face at ball impact and provides a large sweet area to impart a consistently high initial velocity to a ball regardless of the point of impact on the face. In addition, the power-spring body is designed to make the most of the rebounding characteristic of a ball. As a ball stays on the club face for 20% longer at impact than on conventional club faces, the ball gets compressed to the core before rebounding into shape after release, which makes it possible to hit a ball with an initial velocity of up to 1.7 m/s higher.

Up to approximately 7 yards the initial velocity of the ball has improved by 1m/s.

2Reduced BackspinBall’s backspin rate down by 900 rpm to create a boring flight

The MAXIMA driver boasts RYOMA’s patented club head structure, which features a low-spin unit, an anti-roll power booster, and an under-press crown and has a center of gravity lowered to the extent that is roughly equivalent to the space between two grove lines on the face. The lower center of gravity of the head and the extended time that a ball stays on the face at impact combine to reduce the ball’s backspin rate by up to 900 rpm, compared with conventional driver heads. This makes the MAXIMA driver one of the lowest-spin drivers in the industry. A low-spinning ball released with a higher initial velocity and on a higher trajectory has a tendency to stay on a boring flight before making a gradual descent at a gentle angle toward the ground, on which the ball rolls longer.

Meeting three conditions of high initial velocity, high trajectory, and low spin, the
“boring flight” of longer runs is produced.

Flight Performance
What is a boring flight ball?
It is the same kind ball as the flier shot made by an iron. Since the spin rate is extremely small, the ball flies forward without rising excessively.As a result, a big run is produced by virtue of the slight angle of descent.

3Optimum Launch AngleOptimized and consistent ball launch angle

The combination of a low-spin unit and an anti-roll power booster enables the player to hit a ball consistently at an optimum launch angle. Even on a horizontally off-center hit, the power-spring body minimizes the wobbling of the club face; on a vertically off-center hit, the bending characteristic of the power-spring body helps optimize the ball launch angle. The MAXIMA driver ensures that the ball is launched consistently at an optimum angle regardless of the point of impact on the club face. Aided also by the driver’s ability to hit a lower-spinning ball with a higher initial velocity, the player can experience a significantly longer distance on driver shots.

4Reduced SidespinReduces backspin by 60% to lower the severity
of hooks and slices by half

With conventional drivers, a ball stays on a club face for 4.7 ten-thousandth of a second at impact. With the MAXIMA driver, which incorporates the power-spring body, a ball stays on the face for 20% longer—for 5.6 ten-thousandth of a second. This deeper, longer impact of the ball on the face results in up to 60% reduction in the ball’s sidespin rate. Even on an off-center hit, a hooked or sliced ball will lose its sidespin during the flight and return to a straighter flight path toward the target. A diverse range of players—from average golfers to serious and professional players—will have a better chance to improve their scores by taking advantage of the superb directionality that the MAXIMA driver offers.

Even in cases of intentional shots such as hooking and slicing, the width of curve
arising from the head will be less than halved.
