A low profile, wide footprint driver that looks noticeably larger than its measured 460cc. An expanded CORTECH Chamber and 54 grams of back weighting combine to create Mizuno’s most stable ever driver, with exceptional straight-line performance across its wide, inviting clubface.

The ST MAX 230 driver unveils two new engineering enhancements to ensure that stability is backed with impressive ball speeds – a next generation CORTECH Chamber and new Bet rich LFS Ti clubface.

Delivering an impressive ball flight that stays on whatever line you set it.

Features & Benefits

MAX STABILITY

Wide profile, massive 54g back weighting and 40% larger graphite composite for extreme twist resistance to off centre strikes and a straight, predictable ball flight.

NEW BETA RICH TI LFS

A new lighter, faster face material - measuring 9% higher in tensile strength (compared to SAT2041) for a complex multi-thickness face geometry. First introduced on Mizuno's 2024 Tour driver the ST-G 440cc.

EXTENDED CORTECH CHAMBER

A dense stainless steel weight with elastomeric TPU - taking stress from the clubface and creating an additional energy source. Lengthened in the ST MAX and shifted closer to the clubface to maintain ball speeds across a wider portion of the clubface.

LONGER 45 ¾ INCH SHAFT FOR FASTER CLUBHEAD SPEEDS

Possible through the additional stability and off centre performance of the ST MAX head.
