Abstract
Abstract A pipe frame for a two or three-wheeled vehicle is formed by joining lugs having pipe receptors to other frame components such as seat rails and back stays. The parts are dimensioned so as to provide a slight clearance into which thermosetting resin is inserted. After assembly and finishing of the frame, the resin is set simultaneously with the baking on of the finish.
