ABSTRACT:
An improved protective boot particularly suited for use in protecting the shaft of a shock absorber for the front fork of a motorcycle. The boot is characterized by an axially collapsible tubular body formed of substantially impervious, resilient material having multiple series of annular convolutions of mutually unique diameters for facilitating mutual nesting, each series comprising two pairs of convolutions of a truncated configuration adjacently related to a cylindrical annular convolution characterized by opposite walls defining an annular orifice the axial dimension of which varies in response to changes in the length of the shaft.
