Abstract
A motorcycle front fork assembly is disclosed in which a hollow damper rod is connected at its lower end to lower end of a hollow fork leg which telescopically receives an upper hollow fork tube and with a piston at the upper end of the damper rod engaging the interior surface of the fork tube. A float is positioned within the fork tube to float on the fluid within the fork tube. A float tube in which the float is positioned can be provided above the damper piston rod and including a fluid regulation valve. At least one compression port can be provided for fluid communication between a compression chamber defined between the fork leg and the damper rod below the lower end of the fork tube and a valve provides one way communication from the interior of the damper rod to the compression chamber during extension of the stroke of the fork assembly. The valve can include a slide that can close off or open a replenishment hole and a fluid passageway in the slide which is spring biased closed but can be opened. A slide is disclosed that is positioned between two springs which permit the slide to move to opposite directions on compression or extension.
