Abstract
There is disclosed a telescopic front-end suspension system suitable for a motorcycle or motorized tricycle or the like. The suspension comprises a front fork assembly having a pair of top tubes telescopically received in a pair of bottom tubes or sliders. Spring means are carried on or in the tubes and means for damping the spring action including liquid or oil are carried in the tubes. A gas chamber or space is provided in connection with the tubes for permitting gas or damping liquid to escape thereto when the top and bottom tubes are telescopically compressed, the compression raising the level of the liquid in the top tube. A control means is provided for restricting the flow of gas or damping liquid from the tubes to the chamber upon application of at least the front brake, the restriction of gas or damping liquid flow resulting in the telescopic compression of the tubes being restrained.
