Form and Function

The Macho Negro seat hinge is a custom fab part for pro and home bike builders. The mounting strap bolts under the nose of most solo seats to provide a smooth, solid interface between the seat and the pivot bung that must be welded to the backbone of your motorcycle. Two long slots on its 4130 chromoly strap provide a broad range of fore/aft adjustability.

For added insurance, use a drop of your favorite threadlocker when installing the pivot bolt.
