KYB PSF Fork Pistons

New MB1 KYB PSF Mid Valve Fork Pistons for the 2013-14 KXF450 & 2013-15 CRF450. These pistons creates a more linear dampning curve and creates more low speed dampning. The piston decreases the high speed dampning spike that a production KYB PSF Fork has. The Piston uses a simple DU Bushing design instead of the std piston band to reduce friction properties and creating a smoother and plusher ride and feel to the rider. The piston comes WITH A 1.5MM bleed hole which is adjustable for any application.We also use a 25mm rebound shim instead of the std 27mm, to help increase the high speed oil flow that the stock piston suffers from badly.

Fork Mid-Valve Pistons come complete with shims and a setup sheet for the rider if your capable of doing your own forks. Available for the 2013-14 Honda CRF450 and Kawasaki 2013-14KXF450 with PSF Air Forks.

Retail: $169.99/set (comes with pistons and shim kit for each model) Required part for the PSF Revalve
