1mm oversized valves were designed for increased flow efficiency on both the intake and exhaust side. The stem has a thinner design for maximizing air flow rate within the port with the reduced air flow resistance. This design with the materials used also allowed for a lighter product as well.
To maximize the potential of the valves purpose each factor was addressed during the design process from the surface of the valve head (umbrella section) & the Valve Seat, from Stem to Cotter are all optimized with precision for optimum operating & sealing capabilities when needed most during extreme conditions.
