Completely new, the 465 Series represents state of the art high pressure gas monotube shock design. It utilizes a large 46mm bore and deflective disc piston for precise damping. The beefy 16mm hard chrome shaft rides on custom viton seals for low friction and leak free life. The 465 is custom tuned for each application and is completely optimized for each bike, from the damping and spring rate all the way down to the jounce bumper. Every shock is hand-built, tuned and dyno'd in our facility in La Palma, California.
