Head Diameter: 25.00mm / 0.985in. Stem Diameter: 4.5mm / 0.1756in. Tulip: 25deg. Overall Length: 3.125in. Remarks: Standard. All KPMI titanium valves are manufactured from solid U.S. milled titanium bar. The titanium bar is cut, forged and then the stem is pulled from the forging process and cross-sectionally reduced. After all final grinding and machining the replacement valve is encased in a hard titanium nitride shell. We have tested these valves in the lab and on the track. They have proven themselves time after time in many high-demand applications, from a dual stage nitrous motor to a recent Superbike from Hell.2004-2016 fits KAW KX250F
