Maximum MOI for StabilityThrough advanced supercomputing, weight placement within the MAX-K head has been carefully optimised to maximise Moment of Inertia. By pushing mass low and back, the design resists twisting at impact, helping the face stay stable through the strike. This high-MOI construction supports tighter dispersion and more predictable launch, particularly on off-centre hits.POI-Focused PerformanceOPTM’s design philosophy goes beyond MOI, focusing on minimising Products of Inertia. By reducing resistance to twisting across multiple axes, the MAX-K limits side spin and directional variation. This results in straighter ball flights and improved accuracy without relying on aggressive draw or fade bias.Forgiveness-First Head ShapingThe MAX-K features a balanced, confidence-inspiring head shape that prioritises forgiveness over compactness. The refined profile helps reduce side spin on mishits while maintaining efficient aerodynamics, supporting consistent clubhead speed through the swing.Fixed Back Weight for ConsistencyA fixed 11g back weight positions the centre of gravity low and deep in the head. This placement maximises stability and forgiveness without introducing adjustability that could complicate setup. The focus is on delivering consistent performance swing after swing, rather than frequent tuning.Forged Face with H.O.T. TechnologyA forged face insert with H.O.T. Face technology increases face flex across a wider impact area. This helps maintain ball speed and distance on strikes that miss the centre, delivering reliable performance without sacrificing feel.On-Course PerformanceOn the course, the OPTM MAX-K produces a stable, mid-launch flight with controlled spin and excellent directional consistency. Centre strikes feel solid and predictable, while off-centre hits retain speed and stay online more effectively than expected. it’s a driver designed to keep the ball in play and build confidence from the tee.Who It SuitsThe OPTM MAX-K Driver is ideal for golfers seeking maximum forgiveness and stability. It suits players who want straighter shots, reduced side spin, and consistent performance without the need for adjustability. it’s particularly well-suited to those who value reliability and confidence over shot shaping.
