Abstract: A motorcycle fork tree assembly includes a steering axle attached to a top tree piece and a bottom inner tree piece. The bottom inner tree piece is pivotally secured to a bottom intermediate tree piece which is adjustably positioned within a bottom outer tree piece. The fork tubes extend through the bottom outer tree piece and are attached to the top tree piece via plugs having offset bores positioned in one of a number of threaded holes of the top tree piece. The degree of trail of the steering assembly for the motorcycle can be easily and quickly adjusted by the independent adjustment of one or more of the bottom outer tree piece relative to the bottom inner tree piece or the plugs in the top tree piece.
