KIBBLEWHITE - 40-40143T - Tensilite® Titanium Engine Valve - '07-'16 Kawasaki KX250F
Shed reciprocating weight in the valvetrain with Kibblewhite's Tensilite titanium engine valve (40-40143T) for '07-'16 Kawasaki KX250F, CNC machined from a one-piece forging of 6AL4V or 6-2-4-2 titanium alloy instead of a heavier steel blank. A CrN PVD coating with a low coefficient of friction adds impact, abrasion, and corrosion resistance on top of titanium's natural weight savings, which is what lets a race-bred motocross or off-road engine rev quicker and hold higher rpm without the valvetrain fighting itself. Made in the USA.
