FRONT FORK
GENERAL
The front fork consists of two telescoping outer tube/inner
slider assemblies. Each tube/slider assembly has an internal
compression spring which supports the forward weight of the
vehicle/rider. The compression spring extends and retracts to
cushion the ride over rough or irregular road surfaces. An oil-
filled damping mechanism controls the telescoping action of
each tube/slider assembly.
