All KPMI® Black Diamond™ Stainless steel valves are impregnated by a special German process to a depth of .002, with a surface build up of .0002. This Black Diamond process improves wear properties, reduces friction, and provides resistance to corrosion and wear that is superior to chrome and nickel electrolysis plating. Each valve is designed using Finite Element Analysis software, and profiles are tested on our computerized flow bench. Black Diamond Valves are lightweight, strong, one piece forgings with profiles that provide excellent flow characteristics.

KPMI Titanium Retainers

All years of Hayabusa

KPMI® uses U.S. mill certified titanium bar for our retainers. KPMI® Titanium Retainers are engineered using advanced Finite Element Analysis (FEA) software. FEA stress analysis allows our engineers to lighten the retainer without sacrificing strength. All KPMI® retainers are inspected to insure correct fitment on the valve and on the spring. Correct fitment promotes longer component life and optimizes the Performance of the entire valvetrain.
