Revision as of 05:33, 28 November 2010 by Addicted2speed (talk | contribs)
A frame whose main structure connects the steering head and the swing-arm pivot, which the engine suspended beneath it. Spine frames are most often constructed of pressed steel, but can also be tubular construction. Often called a Backbone, "T", or "7" frame as this describes the shape of the frame.
