The Yamaha Inpres Drive Star TYPE S men's iron set 2025 (4-piece) includes the following golf clubs:

• Pitching Wedge (PW)

All clubs are equipped with the SPEEDER NX for Yamaha M423i carbon shaft.

Product features :

• The INPRES DRIVESTAR Iron TYPE/S is a distance iron that goes beyond conventional distance irons and lets the ball fly far without overspinning.

Maximized recoil efficiency through “3-Point Resonance Technology”:

• Traditional irons have a center of gravity that is far from the actual point of impact due to their design. This makes it difficult to fully exploit the efficiency of the shot distance. Yamaha has moved the center of gravity closer to the point of impact by adding a rib on the toe side of the clubhead, thereby maximizing rebound efficiency.

New material "X37" for increased ball speed:

• Thanks to the high-strength and tough X37 material, the initial speed of the ball on impact is improved. A precise casting process made it possible to achieve a sole thickness of just 1.1 mm. The rebound area of ​​the sole has been expanded compared to the previous model, which has significantly improved the deformation of the sole and the rebound performance in the lower area of ​​the club face.

Large tungsten weight in the rear sole area:

• A large tungsten weight (TYPE/D: 41g, TYPE/S: 77g) ensures an ultra-low center of gravity and thus exceptional distances and a high trajectory (center of gravity depth: 6.8 mm, center of gravity height: 18.1 mm).

Shaft & Handle:

• The SPEEDER NX shaft, specially developed for the INPRES DRIVESTAR, offers optimal performance and control.
