Abstract
A front fork yoke for a motorcycle where the yoke includes a parallel pair of posts rigidly maintained laterally spaced apart by a pair of parallel semi-circular arches extending laterally between the posts. The imposts of the upper arch are curved rounded-over shoulders. The front face of the yoke is smoothly rounded-over towards the rear face of the yoke. The arches are upwardly convex and support the motorcycle head tube therebetween.

A front fork yoke for a motorcycle comprising:
- a parallel pair of posts, each post of said pair of posts having an upper end and an opposite lower end, an upper arch extending from and between each said upper end of said each post, each said upper end being an impost at opposite ends of said upper arch,
- a lower arch paralleling said upper arch and mounted to, so as to extend between, said pair of posts adjacent said lower ends of said pair of posts, said upper and lower arches each having a vertice lying generally on an axis of rotation of said yoke when said yoke is mounted to a motorcycle frame so that a head tube of the frame coaxial with said axis of rotation is mountable snugly between said vertices of said upper and lower arches, said upper and lower arches each forming a corresponding concavity under each said arch which opens downwardly towards said lower ends of said pair of posts,
- wherein said pair of posts, said upper arch and said lower arch are one unitary rigid piece.
