Editing Spine frame

[[File:Back-bone-frame.jpg|thumb|left|Back bone frame]]
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.

This type of frame is made up of a combination of pressed steel plate and steel tubing.
This basic frame design is used mainly on scooters and some of [[Honda]]'s early motorcycle designs. Back-bone construction allows added freedom in the overall design of the vehicle and relatively economical production.
